Depending on the brand of spring they should have the spring rate noted somewhere. Hypercoil etches the spring rate on one end of the spring...you'll need to remove it to see though. Eibach stencils a spring rate code on the side of the spring that is pretty easy to decipher. What color are the rear springs?

Thats from the paper work I have, and their black. |

QUOTE Rears are 165 lbs. progressive rate. Thats from the paper work I have, and their black. I wouldn't change anything now, just go have fun. My guess is that ultimately you'll find this setup too stiff on the front and you'll deal with understeer issues when you really push the car. Not a big deal to change at some point and certainly every driver is a bit different in what they want for a setup. Autocross is all about getting the car to turn in/point so you'll really want it at least neutral to mildly loose. 914-4 is a momentum car...your setup needs to allow you to get on the power early. Like I said earlier, just have fun right now and learn your car. |

Like I said earlier, just have fun right now and learn your car. Try to get an instructor to ride with you every time you can. That and seat time is what will get you up the learning curve. I've said this 100 times here on this site, but the best advice I ever got was from Rich Bontempi, who said just concentrate on seat time. And by the way Bontempi has probably beat more big, fast, 4x more HP cars in SCCA competition, with his 914, than anyone else in the 914 world. He goes down to Laguna and drives his mostly stock Viper (another one of his toys) and does lap times in the 30's, so knows how to drive. |
