So I've gone from a MKIV .:R to an B6 s4. I need some advice on my new setup. What can i get away with when it comes to Audi. I'm going on air, so that covers ride height. I ran a 215 on a 8.5 and a 225 (factory 225 tire) on a 10 inch wheel and had no issues. My concern for the 4 motion vs the quattro is the drive line itself, does it use 50/50 on a quattro? I know the haldex is like 70/30, which is almost pointless. Will running two different wheel sizes cause issues on these? I've looked high and low for threads going over this and no one comes to an exact answer. With what widths and et can I go? Thanks for reading my novel.
