Stock front torsion bars, 100lb rear springs, Bilstein HD shocks and oem size sway bars make for great handling that is still very comfortable.
It's very common to see people up the spring rates because they think more is better but you don't get grip when the car is so stiff it bounces off the ground on every bump. It happens a lot in the 911 world because guys don't realize how increasing the torsion bar size ramps up the spring rate. So both ends get increased by 50-100% with just a couple mm change. Big sway bars also affect the ride as well as stiff bushings. I've also lowered my tire pressure over the years since most psi suggestions are for heavier cars. |
