So i got a set of kyb gr2 struts a week ago and my ground control coilovers just came and dont fit. i have read that the "washers" need ground down in order for the coilover sleeves to fit around them but im confused on if this is just the front or back struts. the front and back have different washer pieces that i beleive are just for the original dust boot. are the sleeves supposed to fit down around the strut body or up on top of the washers? any help is appreciated
