265/35 or 25/35 on 9" up front

New wheels are ET30 all round for the changeability thingy, and then im wondering what spacers would work best, as in, do I run my 10mm ones ALL round, or leave them off the front, and put them on the rear, or do I need to buy some thicker ones for the rear? Solutions ?

Been there done that, trial fitted with Nitron. First up was the 12s then 15s on rear only (ET30), I can cut you time by saying they definitely need spacers on rear. Had no issues with rubbing but IMHO you will need more than a 10mm, but thats me. You wont want spacers on the front.

Hm, I remember this from AP's website that they won't fit with 18 inch M3 rims.
I thought the problem was the clearance between caliper and wheel spokes.
I am 100% sure that CP5575 are 'thinner' because they fit without spacers with stock CSL wheels while the CP5555 needs at least a 5mm spacer.

If you could measure the diameter of the 18" M3 wheel, I could check what is the clearance that I have now and be sure I won't have a diameter-clearance issue.

Check the clearance I have in the 19" BBS CH wheels.

Yeah, i fugured 10mm would be on the thin side, so 15mm on rear for you at the minute then Alex?

Will try get some pics if needed. But yes, tested both & opted for 15s over 12s, giving a wider rear track and an extra 2mm over the 12s giving it a more flush fit with the arch. Not a lot in them but enough.

et15 look spot on on the rear (et30 + 15mm spacers)

et30 no spacer on 9J should be a match on the fornt as KK says
