Bought the car recently with bilstein shocks/struts, not sure what springs (red springs--maybe eibach?). The car sits pretty level, and currently has 255/45/17 tires all the way around. The front has a slightly larger gap and this week im changing wheels/tires to 275/35/18 OR 275/40/18 in the front with 305/35/18 in the rear. The 275/40 will help eat up the extra gap in the front, but is like .2" larger. I'm thinking it might be easier to just lower the front a bit or raise the back a bit--but not sure how. It looks like both iso's are in the fronts and rears. Is there anyway to raise the rears maybe .25 - .5"? Maybe thicker isos or something? not looking to do anything drastic, but wondering what my options are....
