18s from F87

Mintsopoulos · 01-22-2024, 02:29 PM

I have a local selling a set of wheels that they claim came off an F87. The specs are:

18x8 ET30
245/40R/18

Any reason why these wouldnt fit my F80 w/ Std Brakes? It would be nice to have a set of beater wheels.

Any insight would be appreciated.

OEM 513M front wheel is 18x9et29 and the rear wheel is 18x10et40. F87 M2 uses the same wheels as the f8x.

18x8et30 is ~0.54” less aggressive (wheel sunk in more into wheel well) and the rim is narrower by 1”. 245/40 is 10 mm narrower than stock 255/40 tire.

On the rear, it sits ~0.62” less aggressive and the rim is 2” narrower than stock. 245 is 30 mm narrower than stock 275/40 tire.

IMO, this isn’t even a good winter setup due to rim and tire widths. These may have been used on a M2 but they don’t match OEM wheel sizes.
