Hi. I just acquired a 1987 325is that I will be turning into a track rat. Car still has the stock 14" bottlecaps. I happen to have a set of Kosei K1-TS wheels with the correct 4x100 bolt pattern, 15x7 with et38. Will these wheels fit? Are spacers or lug bolt extentions needed?
What is a recommended tire size (specifically looking for R-compounds for track use).
Thanks for your help.
