    Recently driven this car at Red Bull Ring on comfort soft to racing hard, much better than in pre 1.09 :) Please try it and let me know if the 599XX needs improvement :)

    Awesome car! And I no idea that there were other variations as well. From my few minutes with the 'standard' 670 Hp car, I can tell that it handles pretty well, it does have some turn-in understeer, but I get that with almost every car in your garage, so it is just our conflicting driving styles. But it more than makes up for it in corner exit traction and really rockets out of the corners. I only made one little change and that was switching the Sports computor and Sports exhaust for a racing exhaust, it gives the exact same HP and Torque, but a much more 'racey' exhaust note. I don't have much time today, so ill try the others tomorrow. Overall 9/10, Great car.

    I am with Pete on this Ridox, you are the most in depth tuner on GTP with the detailed notes. I love reading these and it adds a connection between the car, the tuner, the game and us the drivers. I am more than happy to wait (after all I am a GT kinda bloke and heaven knows we know all about that hahahaha) and prefer to get the proper goods Ridox. Make like INXS and don't change a thing Pleeeeeease! :-)

    Will do one, this is of my favorite tunes of yours R, will add to my b tune as all my tunes are c tune so the original is there. Will test both and report back however it may be a few days now 1.12 has arrived and as my ps3 is on life support it only sees night duty when temps are down and humidity has subsided a bit

    Hey just wanted to say that your tunes are great, always fun, maybe not always my cup of tea for driving but they all force me to learn something while driving them that helps make me a better driver, and tuner. :cheers: keep up the great work!

    Nice car,but more oversteer - only 0,3 s faster than stock R8 @ Madrid Full

    It showed me that GT6 psychics are not perfect - How this 4WD is harder to drive without burning rear tires than some FR ?

    I'm taking my time, will keep doing the notes and pics :p

    Thank you :)

    It's a replica, most of the time will be harder to drive than stock GT6 setup that often wrong / unlike real life counterpart. Most of the time power + torque, spring rate, camber and toe, LSD, weight figure and distribution are wrong in GT6, some even include the gearing. The oversteer is correct for R8 GT, I've read articles about the car, even Audi states themselves, the added camber alignment, upgraded suspension was to allow controlled oversteer when all electronic aids disabled. Stock R8 in GT6 do not drive like an R8 at all IMO :p, too many things are wrong, from LSD, weight distribution ( affect handling ), camber and toe alignment ( 0.60 toe stock is not always correct, rarely road cars have 0.60 rear toe in :lol:, some Ferraris like F430 have 0.50 rear toe in from factory, but it was necessity to combat snap oversteer as the rear wheel gain toe out when loaded )

    Try the R8 GT replica with 0.60 rear toe in, and you will have more stable rear / less oversteer.


    I will also be releasing H&R R8 GT, the H&R suspension kit allows more neutral handling IRL.

    Hey Ridox, if you wanted one car to be tested 1000 miles by someone else, which car would that be?
    I might just do that. :D

    Hmm I'll take the F40 and drive it for 250 miles at Monza, Sierra and two tracks of your choice. ;)
    This will take some time though. :D

    There are 3 version of Ferrari F40 replica, I choose this version

    - The Auto Motorsport Mag 1989 version, please use the recently updated suspension setup ( Best Motoring ride height + stock spring ratio and no fuel weight figure + replica LSD 30/36/36 ) Mmmm. the 2 other tracks would be best at Red Bull Ring ( very enjoyable there ) and Suzuka. You are free to use comfort soft or sports tire :D Good Luck and God Speed :cheers:


    I have updated the replica :)

    Sierra fuel economy:

    Realistic driving style (100km/h speed limit): ~5 liter per lap (~18.5 liter/ 100 km)

    Racing driving style: ~15 liter per lap (~55.5 liter/ 100 km)


    The F40 is really fun at Sierra on Comfort Softs. The track is very fast and the car is somewhat predictable. It takes slow corners nicely and fast corners can be taken in a sort of power slide in a low angle. Countersteer and you are dead!

    Braking is look-free until about 150km/h but there are many sharp corners that you approach at 250+km/h. It is however very stable while braking.


    That's my summary of my first 170km at Sierra.

    I'm using no aids at all and driving in an online lobby with real grip and tyre wear.


    Next goal at Sierra is a sub 10-minute lap. That is an average speed of 162km/h! Rain will be used too in my next session. If you got any specific questions, feel free to ask me.

    Nah, I am on a DS3 and had some time to kill. :dopey:
    Did about 7 laps, that is how long the track is (27km).

    Acceleration Sensitivity: 20
    Braking Sensitivity: 5


    Brake Balance:
    7/9 ( personal BB) or for ABS 0 wheel : 5/7, for ABS 1 - feel free to use your preferred brake balance.

    Recommended setting for DS3 user :

    Steering sensitivity at +1 or +2, all aids off, except ABS 1 ( if not comfortable with ABS 0 ) with 7/9 brake balance as starting point.

    Notes :



    This is one of rarest FF tuned in GT6 :)

    For this build, I used Silk Road RM/A8 coilover damper kit with 5kg/4kg spring package. Toyota VITZ factory alignment range has also been implemented. The coilover allows nice drop at 1 3/4" front and 2 3/4" rear, this gives nice stance and visually level appearance.

    LSD uses TRD Helical Type 1 Way. I retained stock weight and distribution, but I fine tuned the balance via weight reduction and ballast to achieve closer to 62/38 of the real car. With only rear seats removal and spare tire in real life, weight shifted forward to 63/37.

    As the real car and in GT6 is equipped with 175 wide tire and 14 inch diameter, comfort soft will struggle for traction with the amount of power and torque on 450PP, thus sports hard is highly recommended.

    Gearing has been changed from CCVT to 5 Speed Manual, taken from Toyota VITZ RS Manual Ratio. The gearing is well balanced with enough top speed for medium speed track.

    The VITZ F 450PP was tuned and tested at Red Bull Ring Short, Tsukuba, Nurburgring GP/D and Big Willlow. At Tsukuba, it can lap easy 1:06s on CS tire, not bad for a VITZ :) Not as quick as my J's Racing Honda FIT RS Turbo as the VITZ retains stock ratio 5 Speed :p




    UPDATE : Added race alignment setup and some fixes to the toe values.

    Brake Balance:
    6/8 ( personal BB) or for ABS 0 wheel : 5/7, for ABS 1 - feel free to use your preferred brake balance.

    Recommended setting for DS3 user :

    Steering sensitivity at +1 or +2, all aids off, except ABS 1 ( if not comfortable with ABS 0 ) with 7/9 brake balance as starting point.

    Notes :

    This is one of the most challenging replica I ever made, even at the moment of posting, I'm still not satisfied with the handling :p

    The car is based on Paul Cain built BMW 3002 TTii, a 2002 Turbo undergoing modern transformation.

    First, the engine was swapped for bigger size with more power, more efficient, lighter and more advanced in technology. A Dual VANOS 6 Cylinder M54B30 engine from BMW 330i 2001 model. To make more power, yes, Mr Paul Cain craved for more power to humiliate the poor folks who look down on the old banger at the lights. He added 2 KKK turbocharger, a TT package that runs on mild boost of 6-8 Psi, but capable of producing 335HP at the wheel - that translate to 370+HP at the crank with 10% loss on the driveline :eek: He reckons that with lower compression, upgraded pistons, the M54 engine will spit out close to 485HP, possibly at the crank with 12 Psi boost :bowdown:

    To accommodate that much power, the chassis, driveline and suspension needs some serious make over. The BMW received extensive weigh saving, chassis strengthening, custom wheel hubs, custom suspension linkages, custom sub frames, and special custom roll cage for safety and added rigidity. The real car wet weight ( no driver + full fluid ) at 2740lb / 1243kg. The BMW 3002 TTii has 8 US gallons fuel tank positioned at the rear axle ( half of original tank ), I have calculated weight at 1220kg without fuel and fluids. I also have included a variety of ballast + position. The car with driver and full fluids ( fuel and oil ) has 50.2% / 49.8% distribution, this is reflected in the ballast position of -4. Without driver, 1220kg, the distribution should shift rear ward at about 0.5%, reflected in ballast position of 2 ( 49/51 ).

    The suspension is custom built by Jeff Ireland, employing Eibach Race Springs and custom valved Bilstein Damper all around. The spring rate is unknown, so I have to give my personal touch, with handling aimed at good balance, the real car is said to have almost no understeer / neutral turn in at low to medium speed. Ride height has also been visually replicated, with lower front to achieve level appearance like the real car.
    I have tuned the damper and ARB to maintain balance on low speed, while medium speed needs good throttle control, while the real car has good handling even at higher speed. This is hard to achieve consistently, as the BMW 2002 Turbo in GT6 has stock skinny tires, while the real car has much wider 17" 7.5" wide front and 8.5" rear tires ( Michelin Pilot Sport ). Nevertheless, the replica should handle well on comfort soft with good throttle control :)

    The transmission is another part that needs serious attention, a 5 speed Getrag 265 from E30 BMW M3 is used, with final drive at 3.710 taken from E34 BMW M5. The gearing is perfectly matched to the car engine, giving good acceleration and decent top speed. I have included 2 methods to achieve the ratio, both gives the same result, feel free to try them both and pick one that you prefer.

    The LSD is torque sensing Quaife 1.5 way with 25% lock on preload taken from E34 BMW M5. The LSD is tuned to give stability on low to medium speed.

    I have also provided a 450PP power figure spec, simply remove the high rpm turbo kit and adjust power limiter accordingly. I also highly recommend to fit sports hard or sports medium if you have hard time with throttle control.

    The BMW 3002 TTii was tuned and tested at Tsukuba, Silverstone GP, Red Bull Ring, and SSR7 :p At Silverstone GP, with Comfort Soft tires, stock 4 speed, 370+HP, 1220kg, -4 ballast, it managed 2:30s :eek: A good time for such an old vintage car. I have included the replay for your enjoyment and reference, witness how smooth the BMW 3002 TTii carving the track :D something about old vintage look graciously eating up corners that never gets old.

    Recommended setting for DS3 user :

    Steering sensitivity at +1 or +2, all aids off, except ABS 1 ( if not comfortable with ABS 0 ) with 7/10 brake balance as starting point.

    Notes :

    The Ford Focus ST 2013 is one of the car in GT6 that is a stat disaster :lol:, wrong weight distribution, torque figure, spring rate too high and broken gearing.

    For this replica, I made a corrected version, not really perfect, but as close as possible replicating the real car.

    The Ford Focus ST 2013 has 270lb-ft torque, while in GT6 stock value is too low, I have installed intake tuning to get closer at 267.8ft-lb. Power limiter used to get 252HP stock value. Now, onto the weight distribution, the real car has 60/40 distribution, GT6 once again wrong, so I installed weight reduction stage 2 and put some ballast at -50 to get the proper distribution. Curb weight officially at 3223lbs / 1462kg.

    For suspension, the stock spring rate is too high in GT6, and the real life stock value can't be reached ( not low enough on GT6 ). I chose to use the spring ratio instead and set the lowest possible spring rate on GT6.
    The real car has 30N/mm or 171lb/in spring rate at the front and 32N/mm or 183lb/in spring rate at the rear, based on Ford Official documentation, but when tested by well respected suspension company, the actual rates are =

    Front : 29N/mm or 166lb/in
    Rear : 31N/mm or 177lb/in

    Slightly lower than official stats.

    For GT6, I used 4.77kg/mm or 267lb/in spring rate at the front and 5.11kg/mm or 286lb/in spring rate at the rear. This retains stock spring rate ratio, and I have tuned the damper and ARB to maintain balance similar to real life review, nimble with surgical precision while still can bite back on the limit.

    I have also used Ford factory alignment ( camber and toe ), the alignment value used is recommended value by ST experts, while for daily driving factory alignment range are as below ( OPTIONAL ) :

    Front
    Camber ( Driver Side ) : -0.83 +- 0.75
    Camber ( Passenger Side ) : -0.93 +- 0.75
    Total Toe In : 0.20 +- 0.20

    Rear
    Camber : -1.35 +- 0.75
    Total Toe In : 0.38 +- 0.20

    The overall range of values are similar, but the one used on this replica offers better performance at the track.

    Gearbox is another one that needs fixing, the real car uses Getrag MMT6 with dual output shaft which result in 2 different final drive, 4.063 final drive for the 1st to 4th gear, while 5th and 6th uses 2.955.
    GT6 incorrectly set the 5th and 6th, which result on overly long gearing and useless. I have set the 5th and 6th with calculated effective ratio when 4.063 is used instead, this will replicate real life vehicle speed at max engine speed on all gears from 1st to 6th.

    For LSD, I have setup in conjunction with brake balance to achieve similar effect to real life electronic based LSD and torque vectoring as well as cornering understeer control. I have use low preload and medium lock rate to give some locking action which reduce inside wheel spin and give some stability on mid corner, while the rear bias brake balance will help to give illusion of brake based system at the rear axle.

    The real Focus ST uses several electronic system in synergy to maintain handling balance under heavy cornering, there's no mechanical parts that acts like limited slip differential. First is the brake based LSD, which relies on traction control system to maintain traction by applying brake pressure on each front wheel to reduce understeer. The Enhanced Torque Vectoring Control and Cornering Understeer Control work hand in hand on both front and rear axle to maintain balance, encourage oversteer, apply inside and outside brake pressure according situation. With trail braking, the Focus ST can be easily shifted to oversteer on entry, up to certain degree. When the car is really pushed hard at track pace, the brake based system is proven not really reliable, often resulting in overheated brake after several hot laps. When this happens, heavy understeer will slowly creep in which will show the Focus ST true colors.

    Here is a quote from Randy Pobst on his experience at hot lapping the Focus ST at Laguna Seca MotorTrend Best Driver's Car 2013 :


    Several tests review also shown that after several laps, the Focus ST tend to lose it's charm and starts to understeer as the braking performance reduced due to heat build up in the system.

    I mainly tested the car at Tsukuba, Big Willow and Laguna Seca. At Laguna Seca, it can easily lap in 1:48s on comfort medium. The Best Driver's Car lap record is 1:49.30, driven by Pro Driver Randy Pobst ( MotorTrend )



    Below I also provided a picture with detailed gearing and speed stat for the Getrag MMT6 on the Focus ST 2013, and a replay of the run at Laguna Seca for comparison to Randy Pobst lap :p

    Watch it, to find out the similarity and difference in cornering as well as speed at braking points. Drive the Focus ST replica at Big Willow and Laguna Seca and hopefully you'll find pleasure like I do.

    UPDATE : Added optional LSD with low lock to better reflect non mechanical LSD of the real car.

    LSD - 1 Way TRD Helical LSD

    Initial Torque : 17
    Acceleration Sensitivity: 20
    Braking Sensitivity: 5


    Brake Balance:
    7/10 ( personal BB) or for ABS 0 wheel : 5/8, for ABS 1 - feel free to use your preferred brake balance.

    Recommended setting for DS3 user :

    Steering sensitivity at +1 or +2, all aids off, except ABS 1 ( if not comfortable with ABS 0 ) with 7/10 brake balance as starting point.

    Notes :

    The Yaris RS Turbo in this build is a mild modified setup at 400PP, utilizing TRD parts.
    Weight distribution at 61/39 with some weight saving employed.

    Suspension is based on TRD Street Pack Coilover with Fixed Rate Damper, the spring rate are quite soft but gives good natural balance, with stiffer roll bar to reduce body roll under extreme load.

    LSD is based on TRD 1 Way Helical LSD, this ensure good stability and traction even at tight turns.

    Gearing remains stock as I felt for the power and speed, the gear ratio spread is quite good with decent top speed. The Yaris RS Turbo TRD is best suited to low to medium speed track.

    I tuned and tested at Tsukuba, Red Bull Ring Short, Nurburgring GP/D and Autumn Ring. At Tsukuba, with CM tire, the 400 PP Yaris RS Turbo can easily lap in 1:10s.

    Had this bad boy built last month, GT500 and Super Snake, with various Shelby Options :p The GT500 is just as quick as Audi R8 GT if not quicker at Red Bull Ring on CS tire :D

    Mmm, interesting, haven't tried to tune it to full power, long header + no cats = 1100HP IRL :p Let's see if I can find more info.

    I tried that a couple of months ago, The GT500 in game goes to 1015 HP. Unfortunately Shelby keeps their cards close to their chest so there is no info on the suspension. So i just multiplied both spring rates by 1.5. It does handle pretty well, but is very 'lively' on SH, which i think are pretty close to the road tires.

    The Shelby GT500 springs are very soft and not reachable in GT6 :grumpy: There's only one spring set that can be used, and it's an aftermarket springs by the same brand as Shelby used on their cars :p I'm guessing the Shelby 1000 will use similar springs, too stiff on live rear axle is bad IRL :D If the suspension on my replica can handle Super Snake on CS tire, it should handle 1000HP, besides the Super Snake has much higher torque spec if going by real life torque figure.

    The real question is can the torque figure be replicated ? I doubt the GT500 can reach 1000HP with lower torque than 850HP Super Snake :(

    At 1000HP, it has 922Lb-Ft, and i am using the normal Gt500's weight at 1747kg (@55/45) because I could not find any info on weight.

    Edit: I also found a dark blue that gives black stripes, it is Interlagos Blau Metallic, from the BMW Z4 M Coupe '08. It is not an exact match but i think the black stripes make up for the difference.

    Shelby documentation has 2014 GT500 and presumably Super Snake at 3845lbs - Super Snake has more lightweight parts to compensate for added weight from additional coolers, structural rigidity enhancement, power upgrade parts etc. Road test review by Road and Track says 3852lbs. Weight distribution is at 57/43 based on Shelby documentation, the Super Snake will be much closer to 58/42 with more parts added at the front ( coolers, bigger supercharger etc )

    The Shelby 1000 only have 750lb-ft torque :) I also came across magazine article that states most Shelby Super Snake and 1000 weighs about 4000lbs - may include full tank of fuel :p Shelby 1000 uses specialized coilover kit with camber plates and adjustable dampers.

    Found conflicting torque figure :( Some says 852lb-ft :/
