Camber are **** un Gt6
Real FWD race car are -2.5 to -4 Front, -1 to -2.5 Rear with hondas, sentras, Golf, etc. if you try to use that kind off setup in gt6 the setup is ****.
My Nissan s14 (real) are spring rate Front 10, 8 rear, (Camber -3 front, -2 rear) and in the game the car loose a lot off grip with these setup.
The true is the camber in the game is wrong.
Sorry for the english XD
Camber are currently bugged in GT6, zero all around gives max possible grip.
For spring rate, you can use real life coilover kits spring in GT6, fine tune the damper, arb and toe, and it should work well. I've tried variety of spring rates from aftermarket coilover for S chassis, they all work well when matched with properly tuned damper, arb and toe.
S13 coilover for example have a range of spring rates from 4,6,8,10,12. Most are front stiffer than rear, eg : 4/2, 4/3, 6/4, 7/5, 8/6, 10/8. But there are spring from certain manufacturer who uses same spring rate or stiffer rear ( depend of use )
10/8 used on TEIN SUPER DRIFT Coilover Kit, While TEIN SUPER STREET used 6/5 as well as ZEAL FUNCTION B6.
RSR Down Springs has 3/3, while Eibach and Whiteline Control has some that are rear stiffer : Eibach Sportline : 2/2.5, Whiteline S13 : 2.8/3.66, Whiteline S14 : 2.8/3.18 ( for street )
