I have read here how bad it is to use anything but the Autoexe springs since they are designed specifically for our car while the others are not. But I now see two people (p5freek and now Jamespeed6) using non-Autoexe with no problems in a competition environment (autocross and drag racing). It is staring to look like these other springs may be worth the money, I cant spend 500+ dollars to have the other springs imported especially when these other springs seem to be working. Any thoughts??? Any comments p5freek and Jamespeed6??
