So I just recently purchased a set of Rota Slipstreams that are 15x7" w/ a +40mm offset. I test fit them on the front and they have enough room. On the rear however there isnt really enough room between the stamped piece of the spindle that contains the joint for the upper control arm. The very inside edge of the rim has only an 1/8th of an inch of room. I talked w/ a very well read car guy (and honda guy) and he suggested that it should be ok even w/ that little room. This makes sense since the actual stamped piece is a part of the spindle assembly that moves w/ the wheel therefore that 1/8th" should be constant (in theory). I am still worried about this though since they are a brand new set and would HATE to ruin two wheels by hitting a large bump etc.. and it hit. Heres a pic of it I made in paint. And yes my paint skills are horride. Your thoughts?
