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. |

Hey Neilca, From what I've read, you are getting very good feedback on the issue of ride height! I started out lowering my car as low as I could go and the car was a nightmare to drive. I ended up RAISING it back up to 5" because lowering the car SCREWS UP the suspension!!! Please go back to other posts on "suspension setting for V8 cars" (mine is one!) and you will see that I did bump-steer measurements front and rear and found that the car is DESIGNED to run at "about Stock" ride height or we end up in ALL the wrong parts of the suspension arcs. The issues are not only Camber but more importantly TOE CHANGE, especially in the rear. Basically, the suspension is for the STREET and NOT the race track. I have to keep reminding myself that the car was originally designed to run on those tiny 165 radials! As far as how to set spring & swaybar rates for a 411-motor 914, I can't help...but for data on what the suspension does in compression and droop, I can. if you would like the data I measured, feel free to email me: porschepiloto914@verizon.net. I believe it is important to have a basic understanding what the suspension is designed to do, before we dive into big changes. Hoping this helps, Terry |
