ok i was reading all over on this board about NOT TO DO THIS>...well i did it. i put Ground Control Coil Overs on KYB AGX's and I LOVE IT> it rides just as good if not better then when i had my Neuspeed race springs on there. there was one problem though...they told me to trim all but the metal on my dust cover and leave it on there like as if the spring was going back on. well i knew from past experience from other coil overs i have had on my other car you dont' need the dust boot. but they said do not skip this step...so i didn't. well i start to do the test drive and everything settles... well i go out on this road that is pretty bad to see how good it was from stock. well i hear this clangin and banging shit. so i look at the strut and notice the the metal part of the dust cover was hitting were the strut rod starts to go down into the housing. so i rip everything apart and pull the dust covers off leaving the washers that were there in place. and put it all back together..no noises and even better ride. it is just awesome. i never thought it would ride as good as it does. well i just had to say that because most poeple are like don't do it. personally i think that agx's and illuminas are not htat far apart from eachother..along with konis...they may be ahead of the game a little...but kyb is right there with them..just my opinion with experience. thanks.
