Rear Coil Overs... I has them!
And this is BTW, how you run MM rear coil over kit on the street. You purchase a Hypercoil helper spring, and a spring spacer from Eibach.
As you can see at full droop shock length is longer than the spring that came with the kit. What the helper does, is keeping the spring in place, by putting a very slight tension on it. When the car is at normal ride height the helper is fully collapsed, and has no effect on how the car handles. Backing out of my very steep driveway, I've had no problems with spring coming loose at all
While I was there I also bumped the front spring rate as well, so the new rates are 350 front and 250 rear. One thing I can tell immediately, is how much smoother the car rides now, even though that the conventionally located MM track springs (415-515 progressive which turns to 188-233 coilover rate) is technically softer than the new 250 coil over spring. Hoping to see some improvements at the track this weekend.
