Hi
I'm just in this kind of situation right now...did a search and went on this website...
I have a Impreza GC8. Had the KYB AGX suspension and i just change to KSport. With the KYB i had an Oval Camber Bolt for the adjustment.
The guy from the garage, specialist subaru installed everything. On the first test drive, it was great btw, but the right rear tire coil was in contact with the tire...
So far it seem like something he forgot to chk. The next day, we fixed everything and i was able to put my hand between the tire and the coil of each wheel. Not 10 minutes later, my left rear tire just blew up because of the contact with the coil ...
The top mount of the KSport hole is slotted... (not like the KYB, thats why i needed an Oval Camber Bolt to adjust the camber)
We suspected that the Oval Camber Bolt, smaller in size, may be the cause, perhaps it was just not strong enought to keep it in place...
He replace the 2 rear bolt.... i've done perhaps 90 minutes of road with a spare tire, seem fine...
It smell a bit, but that might be just the rest of the flat tire, had shit everywhere.... we remove the biggest part....
The thing that piss me off is not the flat tire, its the fact that i had Perfect KSport and now both rear Coil is missing a 3 cm of rubber on one branch of the coil.... Were still putting a product that looks like rubber but still they aint perfect anymore
Wednesday, i'm changing my mags and wheels (of course) from 16 to 17, 7'' to 8''
but i'm afraid of that....anyway this will all be done in a subaru garage.... and i shoudln't need spacer
