Square setup

[craiginuk]

Hi, does anyone know the sizes for a square setup for the Z4 coupe please? Would 225/40/18 on 8j wheels with et40 offset work? Thanks.

You don't want to go square mate. Bumpy as hell!
Round is definitely your best bet.

Right, back to the vino.
Sorry. :roll:

Yes Craig, they would work fine.

The OE wheels for SE Coupes were Style 200 8J x 17 ET47 front and rear.

I ran E89 18s on my previous Coupe with standard Sport suspension that were 8J x 18 ET29 front and 8.5J x 18 ET40 rear with no issues.

I'm running a 8inch square set up on my coupe. Last year ran standard ET47 on the front and ET40 on the rear. Have now fitted coilovers and although the fronts cleared they looked very tight, so put the ET47 on the front and fitted the ET40 on the back with 15mm spacers. Resulting in a track increase of 14/15mm front and back. Both set ups worked well.

Thanks Guys, I have a set of wheels with 225/40/18 on 40mm offset on the way

They will be fine.

Now I think about it I sold a set of CSL Reps that were 8J x 18 ET40 to another forum member and I've seen a few photos of them on his car!
