I have taken the oz's of and replaced them with borbet 17inch wheels, did anyone else with a big wedge fit different wheels? If you do i would be really interested in a picture! I like the oz's but prefer bigger wheels as the 15inch are just a bit small..
Will look nice on your brother's car as well! What do you want yourself? They are very difficult to get hold of, but the OZ's also exist in 16". The long Kenian just bought a set, may be he knows of another set.
Found out that 225 or perhapse wider is possible on 7,5J..... Going to exchange the 205 toyo's i ordered for the 350i for wider 225 toyo's and perhapse fit spacers at the back.
The dims are a bit awkward for a 400 with 17s. A 215/40/17 is fine or you may wish to take the Stainless approach and fit 235/35s. 225/40s are a bit tall and 225/35s are a bit small.
