RL = 587.3mm (23 1/8") RR =590.5mm (23 1/4") Rear Average = 588.9mm

Tikamak's Ride Heights =
Front = 598mm
Rear = 585mm
I run Front average of 23 5/8" and Rear average of 23 1/4".
With front spring rate of 400lb and 245/40/18 tire diameter, at high speed compression, it will rub the fender liner. I'd love to lower the front ride height but don't want to chew up the liner.
Stiffer spring rate may help but not sure whether it will add more understeer during midcorner than what it is.
The weight distribution with me on the car (no ballast or passenger, half tank) is:
LF 853, RF 835
LR 862, RR 852
Total 3402

With your front 23 1/4" ride, what are front spring rate and front tire size you have ? Thanks
