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. |

Terry,
Thanks for the spread sheet. You are correct the bars have to work harder with the longer arm. I need to spend a little time with your sheet. Is the effective wheel rate the same as the spring constant of a coil over? Truth is I lengthened the lower arms because I didn't want to spend the money for wheel spacers. I am an engineer so, I am very cheap. Once I did that my camber went way out of wack. I always planned to make my own struts so I went with the radical angle. I was shocked, pardon the pun, to find I was now gaining negative camber. Plus I had the zero scrub radius. When i worked on a national GT4 car we used plastic ties on the shock shafts to moniter travel. I think I will do this before I start changing springs. Since Blake was restricted to 5 inches I guess anything lower is goodness. As for having the lower arms parallel to the ground I understand the reasoning however does a lower CG offset the low roll center? |
