Ok, so today I am putting on my 4x114.3 conversion in the front. Everything mechanically goes "perfect" so to speak, everything came off and bolted on with very little to no problems. The conversion came from a 99 Civic Aerodeck (same as the four lug ITR's (Prelude vtecs and Accords for all practical purposes), and quite a nice upgrade from the civics, as you can see.... Anyway, once I got it all together, all the rims were mounted except front passenger side. So I go to put it on and start torqueing down the lugnuts, and then I notice that hte caliper is rubbing. I am using four lug ITR rims. So, I flipped out for a minute and then go to trouble shooting. Took drivers side front off, and put it on passenger side and it fits fine, and then viseversa with the passenger side rim on the drivers side, but no dice, still rubbed. So I lay them down down and start looking at the insides. both 15 6 50. Then we notice that between the mounting surface and the insdie of the cast where the lettering is is a different hieght, as seen below... So me and the guy at the shop figure that there must be a casting difference between the years, as three of them are the same one this one is different, even though they are all four lug ITRs. So, my questions are, has anyone heard of a difference between they four lug years (96-98?)? What route should I take to correct this? Washers? Grind down the saddle a couple mm? Spacers(not sure if they make them that small) Thanks guys.
