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. |

In the northeast most of the SPU cars are 7/8ths pro-stocks or Baby Grands.
Raising the rear pickups can be done several ways. Starting with a chassis jig is nearly essential when doing it from scratch. Some people have moved the stock mounts but the amount one can raise them is limited. Others have developed complex spherical bearing mounting arrangements that are expensive and time consuming to implement. I developed an economical kit that makes it a pretty straightforward procedure to go up as much as 3", retaining the stock trailing arms. It can be done with the chassis set level up on jackstands. The instructions are on my website and are linked on the chassis page. As I mentioned, there are many benefits to rasing the rear pickups. In conjunction with altered trailing arms it is possible to lower the car drastically and obtain very good rear suspension geometry. On thing I didn't mention earlier is the benefit to the toe curve. With your current setup the toe changes pretty quickly in both bump (toe-in) and droop (toe-out). On my car the toe hardly changes through a 6" range of 3" up and 3" down. I keep saying I will finish development of the horizontal fan, then putting it off again. All that is holding me back is that I don't like the shroud design that was provided to me. So I just need to create a shroud I like and the rest will be cake. I actually have all the primary parts to build one more just like the two I have on my race engines. |
