I already had the two 10J ch's, I will test the new 9.5J on the front first then on the back with a wider spacers. If it works I will buy another two 9.5J then I can swap them around.

Tankslapper - Are those photos with the clubsport coilover? Do you get any rubbing anywhere with the 265/35 tyres

Yes there with KW clubsport coilover. their is no rubbing but I have not been on track yet.

The cup tyre size I'm using is 19 x 265/30

Thanks for the feedback. I am going to try with tyres that have 2cm larger diameter which maybe an issue.

Not good. I thought some people got away with 265/35/19 or even 255/40/18 which are pretty much the same diameter.

Do you think I stand a chance if I put 19x8.5 ET20 in the front ?

so same as standard except 25mm less offset and therefore pushed 25mm further out to the wheel arch. Based on the fact that with 15mm+ spacers the tyre seems to foul the arches my guess is on standard geo you will not be able to do this on road.

You may just squeeze the on with 3 deg neg camber for track work!!

I run BBS ch's 19 x 8.5 x et35 with a 12mm spacer on the front which is = to et23 with no problems at all.

The tyre & the wheel was inside of the front arch so 3mm more wouldn't make any difference.

The only down side is pushing the inside of the wheel a further out by 25mm over standard makes the car dart around particularly over bumps as it put more leverage on the steering and it tramp lines more.
