Motorsport rims on a coupe

[Force4m]

I've been offered a set of these. They're 8j on the front and 8.5 on the rears. The offsets are et34 front and et37 on the rears.

Does anyone know if these will fit on a coupe ok or will they foul? They're an 18 rim so tyre sizes are Ok, I'm just not sure about the offset as it's different from what most z4 rims are.

This is a very useful site: Clicky

Shows the standard as:
8Jx18 ET47
8.5Jx18 ET50
(though I'm not sure that's entirely accurate I thought it was more like ET40 on the back @ 18")

So you will probably need spacers, I believe there are people with ET38s on the front that rub on the inner arch lining

You won’t need spacers, these wheels will sit 13mm further out at each corner and will be more flush to the wheel arch than standard. Shouldn’t have any rubbing issues on standard profile tyres, although I stand to be corrected.

Agree with this ^
I have MV3s on my E85, 18 x 8 ET34 front and 8.5 ET37 rear. They fit absolutely fine, and indeed more 'flush' to the wheelarch. You may encounter some slight rubbing on the fronts only, just inside the arch where the bumper joins to the wing but only on high speed compressions or if your front shocks are past their best...I fitted Bilstein B4s just over 3 years ago and they haven't done so since

Quite right I had mixed up the direction of travel in my head when thinking about the differences
