[QUOTE=Phimosis;74379 .......The stock front sway bar in the 370z is pretty close to optimal for agressive street use, but the rear sway bar is just too soft for aggressive street driving or track use......
-Phim[/QUOTE]

the balance of the stock 370z is a bit understeer. for auto-x, i would prefer a more neutral feel. for track, it's actually not too bad. the stillen front bar is 27% stiffer than stock and rear can be adjusted to up to 70% stiffer than stock. but you're saying that even with the stiffest setting in the rear, it's still understeering? i dont understand.

what i would guess based how the car feels to me is that the rear needs to be about 15%-20% stiffer relative to fronts for a neutral feel. (all else staying the same). in other words if the front bars increase by 27%, i would want the rears to increase by 47%.

70% would be big time oversteer, it would seem. but sounds like this is not your experience.....
