I have just removed these from my 400E, and they are available. They are OZ Racing 17" x 8" X 35 mm offset wheels, with Pirelli MA V1 235 x R45 x 17 rubber, with 55% - 65% tread wear remaining (measuring 3/16" - 1/4" tread wear depth). They were scrubbing under hard driving. They were fine under normal driving. If they are installed on a 124 with stiffer (not lowered) springs, or stiffer shocks they should not scrub at all. Asking price for all is $500....Am told be previous owner that they cost him $3000. One wheel only has some curb rash and one wheel has some light face scratching. Bolt pattern is 5 x 112 mm.
