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

[shimmy]

just OEm rear 9.5J

9 might be ok at -2 camber

my front rims are et37 9,5J and i managed to only put 3mm spacers on to clear the strutt. If i hadnt have chnaged the strutt follower spirng i may have needd 5-7mm spacers making it et30-32 which with 9.5J i still think will fit with -3 camber as well as -2 camber

et27 9.5j doesnt fit with -2 camber 9hits the arch lip)

So.... would a good setup with my 9J's all round with 265 Cups on , be to run a 10mm spacer perhaps on the rear and the fronts straight on, or will the front rub do you reckon mate?

[DuncanR]

Nah you wont need them at the front. What ET you thinking at the rear Duncy?

Well I have a set of 10mm spacers all round at the mo running OEM wheels back and front, so was thinkin i would need to spacer the rears a bit as im dropping from 9 und half J down to 9J:bigcry:

Cool. if you just rubbed at 9.5J et27 I should be OK with ET26 9J as i will have 5mm more clearance and an extra -.5 degree. :thumbs:

So Im guessing you mean ET30 all round? Otherwise an ET15 at rear is perfect or a 12/15 mm spacer at rear only, to get the rear out wider than the front and for cosmetics of course. Fill those arches!!

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 ?:smokin:

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.

You may have a problem - the CP5575 calliper was created so that 18 inch M3 rims fit over them. IF you have CP5555 they may be too large diameter so your 18s wont fit!!!! - no spacing will fix it (maybe)

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. :thumbs:

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
