Ok, I have been looking for a lowering kit for a while, finally won a set of coilovers of ebay, extremely happy, but the only issue is that the kit lowers between 55mm and 85mm......my concerns are that I have 17" Audi S3 alloys which I think are 7,5J, will the tyres scrub againt the arches as 55mm might a bit too low?? The reason I ask is becuase on standard suspension the rears touch if I got over a bump too fast or could that be because my shocks are worn out??? Thanks
