Hey guys, yesterday I finally got to install the Energy Suspension coil spring insulator on my D2, man oh man, that's a whole world of difference now, no more weird noise coming from the front suspension just a quiet smooth suspension. The coil spring insulator diameter where a tinny to small probably not more than 1/8 of an inch so it ended seated perfectly once the car was on the ground. I just did the front one, next week-end I'll do the rear. I suggest anyone who has the D2 to do that you will be surprise the difference it make.
