I just bought an '06 Civic LX with SI wheels and I noticed the brake calipers looks like they're touching the wheels. I checked the backside of the wheel and it's all smooth....no rub marks or gouges. Are they supposed to be so close??? The space appears to be about 2-3 cm.

 

I am not an expert by any means but i know for a fact that the spacing for wheels on a regular honda and a SI are different.. you may want to look up the spacing measurements

 

as long as there's no rub marks it should be good the calipers are not going to move from where they are
