I was just wondering if any of you have rubber strut boots on your struts. When I put on my coilovers I had to get rid of the factory metal one. Now I have ordered a set of KYB GR2's and was wondering if it is necessary to use these or if it even matters.

YES!!!!!!!! if the strut/shock rod becomes dirty, it WILL damage the seal. Resulting in, guess what? A nice leak & now you need a new strut(no warranty) because of a $15 part. Now is a good time to replace the upper strut mount bushings as well.

Don't forget to cut the bump stops in 1/2(shorten)

KYB makes both - www.tirerack.com

Why cut the bump stops?

Why cut the bump stops?
The bump stops should be cut to increase suspension travel reduced by lowering. You don't want to leave them off because you run the chance of bottoming out - metal to metal. Not only can it damage the suspension parts, it could hurt some one in the car.
