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. |

(IMG:style_emoticons/default/popcorn[1].gif) I believe the concept and creation of cantelevered tires is to allow a larger tire WIDTH to be used on a specified (smaller) rim. It,s deffinately a competative advantage for the user and tire manufacturer. Lowereing the car (any car) can be a tricky business. Primarialy you want to keep the suspension in a range of vertical travel, bounce and compression so the suspension does not "bottom out", meaning has no more travel. Thats when the car gets out of control quickly, and all this usually occurs at the most critical points on the track. A suspension with too stiff springs essentially replicates this situation. A too stiff suspension gets less traction in turns and down the strightaways. Other people on this forum have given some very insiteful reasons why lowering too much is detremental, relative to (ackerman effect) suspension toe changes in movement, both compression and bounce. You may want to consider approaching the ideal ride height, lowering, by having shock travel indicators, sleeves on the shocks to determine actual suspension movement when on the track in practice or a race. getting some real time/ use information. Having a car with a too stiff suspension,and lowered into a range that is determental to the suspension design is easy to do. It may well be the most common reason for a poor performiong car.The best engine, and tires cannot overcome a lousy suspension setup. ...this for your consideration.
