This is probably a really stupid question but anyway..
So I have an R34GTT which come with 17 x 7.5 wheels standard (as we all know..) my question is when I fit new wheels (Front 17x8 - Rear 17x9) is the overall diameter of my wheel+tyre going to change..?
Someone said it would, hence my car will sit higher etc..but my thinking is, if its the same size rim (in diameter - 17") why would the profile get larger..?
