    While waiting, why don't you try the Legacy Wagon and GT86 rally car ?

    Legacy Wagon - in my opinion it isn't something for me
    GT86 rally car - Maybe later , now I'm having fun with your Gallardo GT3 and non-officially tuned Aventador LP750-4

    I think that is to exit the corners quickly as you can. ;)

    It means understeer, usually caused by too much throttle / speed when exiting a corner and not enough front grip / rear has more grip. Running high LSD initial and accel can cause understeer or oversteer when the rear break loose earlier. Most tuners will use low value initial and accel to lessen understeer and outside tire losing traction, it's easier to get on the throttle with near open diff, but traction will be less optimal. I think low / close to open diff value are chosen for ease of driving :)

    Well, I can't say you didn't warn me about this thing. I just finished my first lap around Nordschleife and I'm pretty sure I totalled the car! LOL! First of all, I haven't a lot of experience driving on CH tires. So, I had to contend with that. Also, I should have payed more attention to your notes where you mention taking it easy on cornering speed. With the weight balance being what it is and the poor quality tires (CH), the back end was trying to come around on me more often than it was staying straight during my lap.

    I have no doubt that with repeated driving I could learn to enjoy this car. The whole reason I love your garage is because I'm trying to experience what it was like to drive these cars, as they drove in real life. Many people who play GT6 have their Ferrari GTO's handling better than a modern day C7 Corvette and that's just not how it would be in the real world. I want to experience these cars, warts and all.

    Don't get me wrong, I absolutely love tuning up a car for quick lap times and having a go with my friends - especially in the Seasonal Events. But there is something a lot more satisfying about finishing a lap at Nordschleife with a car like the 1981 512BBi Replica, massaging your forearms because you were sawing wood for the last 9 minutes and thinking "wow...that car really IS a handful like they say..."

    You definitely want to get your braking done before turn in with this Ferrari. She will want to come around on you otherwise. And don't be surprised when you let off on the brake pedal and turn that wheel, you're going to have to immediately rest your foot back on the throttle to keep the car from transferring all its weight around on you. It's not the most natural feeling in the world. I would imagine the old style 911's were very similar.

    I'll give the 1980 512BB Replica a try at another date. Tonight I want to just do some driving with this crazy animal. I don't think I'll ever be able to tame her, but hopefully I can convince her to stop trying to kill me EVERY chance she gets!

    :scared: I just killed a test driver in a horrific accident at the Ring :lol: Would you be surprised if I tell you that comfort hard still has higher longitudinal grip / straight line acceleration grip than the real car ? I tested 0-60mph and 0-400 performance, and the replica still a bit quicker by a few tenths. The lateral G limit is similar on CH though, comfort hard on most sports car in GT6 has very good lateral peak G's - high 0.80 to a little over 0.90 G.

    I think the rotation caused by the higher front ride height is one of the factors that make the 512BB rear end swing around wildly ( GT6 reversed ride height ). You can try to lower the car and have the front slightly lower like in the White 512BBi pictured on the replica post. Increasing front and rear toe in also helps a lot. From my research, there's a reason why Ferrari used very high toe in on front and rear. The 512BB back in the day with factory tire were a handful when driven hard on the road, it can snap back violently if running near to zero toe all around. Which is why all came from factory with very high front/rear toe in, at least 5mm for the 512BB and 3.5 to 4.5mm for the 512BBi ( rear ).

    A good place to used to the car is Red Bull Ring :) You can also try comfort medium/soft, most 512BB/i IRL now have high performance wider tires that has immense grip compared to the original Ferrari tire back in the 70's and 80's, they would be crazy to fit same skinny tire :lol:

    CH tires have higher straight line grip, really? Wow... I believe you, I just am shocked because I could have sworn that my 1981 512BBi Replica was spinning the tires in 1st once the revs got high. I just didn't expect that from the power to weight ratio and gearing. Like I said in my OP regarding this car, I enjoy the challenge of respecting what this car's limits are. I'm as guilty as the next average GT6 player who spends more time riding SH/SS tires than he should and therefore get used to an unrealistic level of grip all around.

    I'm going to take her up to the Red Bull Ring right now and see how she handles on that track. I expect to make it out of the car with my life this time... :D :lol: :tup:

    EDIT: I drove several laps around Red Bull Ring with the CH tires and then threw on a pair of CM tires. The CM tires are still a handful, but worth about 3.5 seconds off my CH time. I like this car!!

    :D Good to hear :p If you want to run a simple test, go to SSRX, stop at start line, and do a full throttle run to 1000m. Watch the replay, go to bumper cam, press R1 to bring up HUD, pause at 60mph, and at 400m and 1000m.

    0- 60 mph at avg 5.6s, 400m at 14.2s, 1000m /1 km at 248kmh/154mph at 25.1s. The 0-60, 400m and 1000m time are valid for both 512BB and 512BBi. There are range of times for 0-60 from flat 5s as reported by R&T test in 1978 ( US DOT 512BB Carb ) to 5.8s from 512BBi.

    I've always wondered how accurate 0-60 times are in this game. For some reason, when I'm playing, 60mph seems to come awfully fast. I'm not just talking about cars that I've modified and increased power by 150hp and 100lb/ft of torque. I've tried using SSRX to measure 0-60 times but it's impossible to reset the timer to 0.00 before I launch. Frankly, I'm a little confused as to how you measure 0-60 times. You mention stopping at the start line, but the timer will continue to run, won't it?

    When you do free run ( test drive ), the timer sits at 00:00.00 while the car is auto driving. Stop before the start line inside the tunnel, timer will not run as long as you are not passing the start line. Get as close as possible to the start line, use bumper car to do this. You can then launch the car, and run until 1000+m mark. Exit then play the replay, bring up the HUD and bumper cam, pause it when you hit 60mph :p

    Thanks I'll need to practice on a track I'm used to. I used to play GT5 alot with AIDS though, then when GT6 came out the handling and tire grip was alot different and the brakes were horrible but with a patch the brake problem was fixed but the AI either don't know our cars are on the track or only scripted to run a certain lap time compared to ours AKA Rubberbanding :banghead: So I took a long break then finally decided to play again took over 3 hours to update and intialize the updates that was insane :mad: I still can't believe the beast that is the 2014 Camaro Z/28 best track car Chevy made and 2014 Camaro ZL1 the most powerful Camaro produced are not in the game yet :confused: It's a shame a replica is our only option, to begin with the 2010 Camaro SS is poorly programed weight distribution is wrong 48/52 backwards very weird

    Quick Question.
    Would a Live rear axle be setup in GT6 as an open diff (5) or a locked diff (60)? I can't figure out where it belongs.

    Depends on what the real car has. Having live rear axle do not mean it doesn't have some sort of limited slip differential. Live axle doesn't not mean always an open diff. For example, early Caterham 7 uses variety Ford and Morris live axles that were fitted with Titan LSD by owners, some were upgraded with Quaife LSD. Quaife sells drop in / direct replacement ATB Helical LSD for live rear axle ( Ford )

    Brake Balance:
    8/7 ( personal BB) or for ABS 0 wheel : 6/5, 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 8/7 brake balance as starting point.

    Notes :

    The Audi R8 GT is the sportier version of the vanilla R8, with lighter weight and more power, it can be said that the R8 GT is like Superleggera version of the Lamborghini :p

    This replica is aimed to replicate the lap time posted at MotorTrend 2011 Best Driver's Car. For this build, I provided 2 suspension setup. The main suspension setup is based on H&R Coilover for Audi R8 GT, while the 2nd is based on stock suspension. Both are running the same camber and toe alignment.

    H&R Coilover Kit comes with 742lb/in or 130N/mm front and 571 lb/in or 100N/mm rear spring rate based on infos gathered. To accommodate the softer rear springs, damper and ARB has been tweaked to give better balance.

    For stock suspension setup : the Audi R8 GT uses Eibach Springs, the front spring rate is known at 110N/mm or 628lb/in, ID 70mm and 200mm length based on a report from an owner who took a look at the spring markings, unfortunately no such information available for rear springs. I have to make an estimation on the rear springs by cross referencing Eibach ERS catalogue and decided on 120N/mm or 658lb/in spring. I taken into account the Gallardo stock spring rate ratio :) The chosen spring rate works very well for the car, and I tuned the damper to be firm, precise, yet easy to ride on the edge. The Audi R8 GT features sports manual adjustable coilover system with 10mm lower ride height than stock vanilla R8 as standard from factory. The R8 GT factory alignment also has higher base camber front and back at 1.5, with similar toe alignment as stock R8.

    The LSD is 2 way at the rear, similar in arrangement as Lamborghini Gallardo with mechanical locking differential at the rear axle that provides up to 25 percent lockup when accelerating and up to 40 percent on the overrun/coast.
    I have no confirmation on the front LSD, the GT6 stock LSD has the front with some locking, so I decided to use LSD setup with 25% lock at the front axle ( 1 way ) - this will be the main LSD setup, with optional open front LSD listed as well.

    The rear wing of the real R8 GT can't be replicated as there's no rear wing available in GT6 :(, but the fixed aero values makes that moot, the R8 GT replica has more than enough downforce to make it stays planted at high speed, one of the key differences the Gallardo SL replica :D

    I tuned and tested the Audi R8 GT H&R at Tsukuba, Red Bull Ring and Laguna Seca. The main goal is to replicate or beat the Randy Pobst lap record at Laguna Seca during the MotorTrend 2011 Best Driver's Car event. Randy posted 1:36.39s while the replica driven by me, managed 1:36.256. I have included the replay for reference.









    UPDATE 1.15 : Corrected toe values.

    Interesting project :D Building your own car :tup:, you are already halfway, knowing inside out of your own target build.

    Thank you, it's different than the stock R8 GT posted before, I like H&R spring rate better, well suited for the car.

    I will post these 2 tomorrow :

    Ridox, I love all your No drivers assist tune . Can't find a RUF BTR '86 in your tuned garage... I hope can get a fine tune from you with 450hp 1240kg with sport medium tires for Brand Hatch GP Circuit. I''ve tune one myself but really hard to drive fast. Timelap is only 1:36.2 with my DS3. ( All drivers assist OFF) Is it OK or not with this timelap? I temporarily can't use my G27 due to my arm injury. Hope you can guide a help tune a little if my laptimes is too slow.. Thks Bro!

    Sorry mate, my hands are full at the moment, and won't be free anytime soon :( I have limited play time during the week and need to post finished cars. The time I think is quite good for the car and tire if using replica based build ( rear heavy 39/61, stock gearing ) I suggest that you try to adapt the Porsche 996 GT4 ( RUF RGT ) "stable" suspension + LSD and gearing, it might just work :)

    So I'm new to here(both the game and racing in real life)and as a guy who don't own a car,I must give a big hand to Ridox for giving me the opportunity to try the cars out!Thank you very much;-)
    And hopefully we can see more of your tunes in the future,especially replica of supercars(one for huayra will just make my day) and racecars(maybe some Le Mans and Group C cars?).Maybe it's just me,or is that the default settings of cars in the game actually don't match the real life tunes?O.oSometimes it feels way different to drive a stock car in gt6 compared to the videos showing how the stock cars are.

    Thank you for visiting :) I'm very busy at the moment, can't promise on Le mans and Gr C cars, they are expensive too :p For default settings, most of car stats in GT6 have errors, mostly weight distribution, some are HP figure, torque, gearing. The most annoying part is suspension spring rate, I think over 90% cars in GT6 has incorrect spring rate, either too stiff ( common ) or too low ( less common ), and even worse, the correct stock spring rate often can't be reached as the adjustment range often can't get low enough :grumpy:

    Anyway, those are the main reasons, most cars do not drive realistically, apart from higher grip tires :D
