Anybody else here ever run the GR2s instead of the AGX's. Whenever I hit a bump the rears make a pretty loud clunking noise. Sounds the like the mounting plate is hitting the strut tower. Im running the GC 300/200 setup as far as springs. Any ideas...also one thing I did notice..when I installed my GR2s..the rear nut in the center of the shock goes all the way down but for some reason the black rubber bushing that used to compress and sit right up against the nut doesn't anymore. Any ideas guys?
