Tuner Comments

The car was tuned to tackle the Nurburgring online without spinning out every 5 turns, and it does that. In addition, she probably wouldn't make that bad of a daily driver. The car does slightly oversteer if you brake hard and turn at a high angle.

The car was tuned to tackle the Nurburgring online without spinning out every 5 turns, and it does that. The car is able to powerslide if you use the feint technique. In addition, she probably wouldn't make that bad of a daily driver. I haven't bothered with anything like Clutches or flywheels as they wouldn't affect cornering, but the car would probably be faster with them.

Good formatting, easy to read. The flywheels can have an effect on cornering, it can be detrimental in some cases, best option can be stock or sports flywheel. You have to test each with each car you do, semi-race may work best on speed circuits but show touchier handling in slow cornering scenarios. Single plate clutch is most often fastest for rolling lap times on almost all cars over stock and twin plate; twin plate tends to be benefiical for first lap starts from a stationary grid, but slightly slower in shifting and off throttle inertia after momentum has been achieved.

I also like anyone who posts a tune using Sport Softs... I get tired of seeing everything with Race Softs.

Hear, hear. More production car tunes on Sport Softs please. Can't stand regular cars being clad in slicks. Racing tyres on racing cars only, ta.

Zhu8, I'm curious to know your reasons for not installing a FC LSD. Is it because you didn't want to configure one, or do you think the stock diff is better?? I ask, because I'm looking to have a go at one of the Legacy B4s, and I've read that some of them have sophisticated diffs already installed. I've also read that the suspension has been given a good going over too.

I don't have the real world resource that I can refer to when considering what I should and shouldn't put on a car. I don't want to be a nub who just throws everything at a car, and then wonder why I spend most of my time spinning into hedges..!!

Thank you...

I didn't install a FC LSD because I don't really know how to configure one yet.

make your own then

I do already, check my tuning thread...

In some cases, cars that possess unique features in real life have had them implemented in the game; electronic spoilers, the veyron that lowers itself at high speeds, other features can be more difficult to detect but it's possible some stock differentials are more sophisticated than simply glimpsing at the numbers included in their gray out adjustment. See the following regarding the 2010 Impreza...

Driver Controlled Center Differential (DCCD) All-Wheel Drive exclusive to WRX STI: DCCD uses an electronically managed multi-plate transfer clutch and a mechanical limited-slip differential in conjunction with a planetary-gear-type center differential to control power distribution between the front and rear wheels. Featuring manual and three automatic modes, DCCD splits power 41% front and 59% rear. Sensors monitor parameters such as wheel slippage, steering angle, throttle position, and braking to help determine torque distribution and direct it to the wheels with optimum traction. DCCD also features a limited-slip helical front and Torsen® rear differential.

Don't know if it's been commented already, but I can guarantee you that the car will handle better with a higher ride height than what you're using, in fact it will handle better with the stock height compared to the low setting you have. With that low of a height, and with that soft of springs, you've compromised the handling ability of the car as it came at stock because you're inhibiting the springs and suspension from performing the best they possibly can. This is my favorite car on the game, so trust me, I know. I wouldn't go any lower than -15 for front or rear.

me too..

I also want too see some reference times of your tunes and the track the car is tuned for. ;)

Yeah, I thought about that, but I typically drive with DS3 pad and AT shifting, wheel drivers around here easily run 2" faster laps than me on my own tunes. When I get a wheel I may add some for reference, but at the moment, to be honest about my own they just don't look that impressive. Generally, I tune towards consistency so whatever your pace or skill is you'll find you get repeatable times. If you're asking this guy... my mistake, but he's probably in the same boat. Damned if you do, and damned if you don't, tuners might not be the best drivers is my disclaimer :P

If this setup handles like the bone stock ´04 Sedan WRX STi spec C then the setup is ok. ;)

@budius I drive with DS3 too (D-Pad/Buttons).I don´t have a prob if someone drives 2" better with a wheel.
If I can do better times with the stock version of the car then the setup is crap.;)

IMO, the car will turn MUCH better if you modify your LSD settings:


LSD: Initial Torque: 6/9
Accel: 8/15
Braking: 5/5

Then give is a go ;) If you are unstable under braking, bump that up to like 7/6.

Also, more rear spring - 13.0.

I mentioned in the original post that it's set up for the norschedlife online.
 
So....all I need to do to screw up your car at Nordschlife is have ASM prohibited in the regulation settings?? 💡

Take the ASM off and adjust your settings to compensate. 👍
 
I mainly tune for drift but, you should get handling if you raise ur height by 5 and make your rear shocks... Actually I will do everything you did and see if I can make improvements, I dont see how people can be 100% positive just by looking at stats. Reason why is because if everything Down to diff's are modeled what else is there.

I'll get back with you when I do it. Hopefully tomorrow.

Nice find... I completely missed that when I skimmed over it.
 
I ALWAYS study what the competition does to the last detail, no matter how big or small the tuner/tuning garage is. ;)
 
Tune Updated, I managed to get a 7:44 after spinning out, But I'm not a good driver in any way.
 
With the risk of sounding stupid, can I use this tune when my car is race modified?

First post here, yay!

Never got around to trying that, I do have a RM Impreza laying around somewhere, I'll get back to you soon.
 
Hi Zhu8

I was looking for a tune setup for the Imprezza 22B and used a combination of your setup and powell145 thank you both :)

I used this setup to do the Seasonal Nurburgring and I managed to win JUST!! I ran it a few times with a laptime of 7:36 using AT transmission (not a good driver) lol. The car sticks to the road like glue!! It turns in brillantly and is well balanced with no understeer/oversteer. I managed to keep it of the grass!! lol!! I found that the LSD Brake Sensitivity setting set at 8/7 when braking after a long straight the backend becomes abit unstable, hence why I have adjusted the braking sensitivity to 10/9 but have not tested it yet. Thanks Zhu8 and Powel145 job well done 👍
