I am setting up an EP 914-6 for SCCA regionals. I have 22mm front torsion bars and 350# springs in the rear. How low can I set the ride height? I have found the bolts that hold in the front sub frame to be the lowest point of the car and I can adjust the bars till it hits the ground. The rear I use the jack points on the back corners of the tub. I can lower these down to 2" off the ground. I have a set of the 23mm front bars also and can get heavier rear springs if needed. Any suggestions? I am runing cantilevered slicks from Goodyear. I will be running tracks like Road Atlanta, Barber, Roebling and CMP. How low can I go? Thanks, neilca. |

Thanks for all the feedback. My car is far from stock. I have:
Lengthened the lower control arms 2 inches, then changed the strut angle to compensate, which gives me one degree of negative chamber per inch of bounce. This also allowed me to tuck the ball joint into the wheel so I have almost a zero scrub radius. I spent a lot of time fixing the bump steer from all these mods, but I got it down to 0.03 through the entire arc. The inserts are Bilsteins for a Scirocco. These are a lot shorter than the 914 inserts. I made my own sway bar from 0.080 wall 4130 1.25 in diameter. It mounts in the usual place. The rear upper mount has been raised and I use a set of aluminum Pro shocks. The engine was raised in the chassis in order to improve the driveshaft angle when the car is lowered. The car weighs about 1800# with the driver. Any suggestions on spring rates or shock travel? neil |
