The 235s up front do not rub at all with the exception of a small bit of hard, sharp cornering caused by some body roll and dive. I really need to upgrade to some M030 sway bars, and that should take care of it. Other than that, 99% of the time they're fine. I'm also running a degree and a half of negative camber now which should also cure it (haven't driven much since the alignment) You may be able to run 245s with a bit of negative camber, but I couldn't say for sure. You don't need to run any spacers as long as you've got the proper offsets, ET50 up front and ET65 rear.

Hello!
I had a small question for you please....i have a 87 944 turbo and i'm about to buy my02 wheels.
Did you need any spacers up front with your 235/40/18 setup? Will 225/40/18 work or will i need spacers.i guess i'm really looking for the best tire fitment up front,without having to run spacers and wanting to be as flush as possible without rubbing.
I'd love to hear your feedback and i really appreciate your time.
Thanks a lot
David
