OK, so I've just sold my Supercharged E92 and I should be back in a 46 M3 this weekend, thinking of getting some 18" ARC-8 rims.

Whats the best set-up on these for a 46? Width, offset etc. Would really like to run a 265 section front tyre.

10j et25 or 9.5j et22 are the most popular sizes for a square set up

I went with 9.5j ET35 on the EC7s, fronts fit perfectly, no spacers, flush with no rubbing with aslight bit of negative camber whilst lowered, rears I have on a 10mm spacer, but could probably go to 15mm, but still look good. I'm running 265/35 michelin ps4s all round as well.

Are you running 18ís? Didnít think you could get PS4S in 18ís?

Do the 10j fit with no issues of rubbing?

Have to run -2.3 camber or more and it also depends on your castor setup because they can hit your front inner arch

So safer to go with 9.5j?

I run 18x9.5" ET35 front and 18x10" ET25 rear. I personally think the 9.5" ET27 fits better on the front, if I were to buy again that's what I would go for. Cant say if they'd rub on a standard geo setup but mine clear fine with roughly 2 degrees of camber all round and quite low.

The car I'm looking at has adjustable top mounts on the front and adjustable rear arms too so I will be able to dial in some negative camber. What tyres do you run front and rear?

You'll be fine then, as you say you can adjust it to suit. Tyre wise I run 265/45 rears and 245/45 fronts.
