I use this place to write my progress when tuning a car. I choose car that mentioned as having problem. You can write your own experience when tuning your car too. car: Nismo GT-R LM (R33) Civic CRX Si '91 Mitsubishi 3000GT LM '99 Ford RS200 Rally Car Alfa Touring Car Jagular XKR Lancer evo V '98 Skyline GT-R R34 V spec Corvette Stingray '82 Shelby GT350 '66 Ford Saleen Mustang Tuscan speed six BMW 328Ci RUF CTR Yellow Bird RUF CTR 2 Sport Test setting used on all car spring rate - 12/12 ride height - max/max damper b - 10/10 damper r - 10/10 camber - 0/0 toe - 0/0 stabilizer - 1/1 BBC - 24/24 gear default LSD - 1/1/1 supersoft tire. The track is deep forest or autumn ring. Nismo GT-R LM (R33) - "Heavy, sluggish to turn, and spins out every tiem you brake hard" Using test setting the car feel slightly understeer, with some rear jiggling in deep forest. Adjust rear damper (10/6 10/6). The jiggle is reduced, and the car feel slightly oversteer now, it reach 1:10 in deep forest. Next tuning should be the brake, but as I don't feel bothered by current brake I leave it as it is. Civic CRX Si '91 - "I mean, LOTS of understeer of all types" Using test setting the car feel slightly oversteer, I don't think it need tuning, it is already agile and drivable. Don't know why they feel it understeer. Mitsubishi 3000GT LM '99 - "This car understeers everywhere" Using test setting the car feel slightly understeer, with some side jiggling in deep forest. The acceleration is not smooth. Adjust stabilizer (7/7) and using higher final drive (auto 21 at 5.500). The acceleration is now smooth, but the side jiggling still exist, reverting stabilizer (1/1), adjust damper to lower value (6/6 6/6) The side jiggling reduce a little, the car feel more understeer, adjust damper to lower value (2/2 2/2) and increase rear spring rate (12/14). The side jiggling is reduced, but the car still bouncing, the handling become little oversteer, the next tuning goal should be reducing the bouncing which can be done by using lower ride height. At this stage the car reach 1:09 on deep forest. It turn out that I can still improve this car handling, 1/1 1/1 damper, 2/1 stabilizer to reduce mid corner oversteer. Ford RS200 Rally Car - "but the body roll in this machine is impossible to fully remove. Lots of it" Using test setting the car feel like using low spring rate, many body roll, the handling is understeer, the stock gear is weird, long at higher gear. Adjust spring rate (20/20) and using FC gear (auto 14 at 2.5) The acceleration become rough, the handling become oversteer with tendency to spin on each corner Using lower rear spring rate (20/16) and changing final drive (auto 14 at 4.5) The body roll mess the handling again Reverting to stiff spring (20/20) and raising rear LSD (1/1/1 56/56/56) The car is more drivable, still oversteer but not spin happy anymore, body roll still exist but not messing the driving. Increasing front stabilizer to 2/1 reduce oversteer Lower ride height will help reduce the annoying body roll more.
