RIMS: Will A6 18" 5x112 43 offset fit?

Hi,

Will A6 wheels - 18" 5x112 with 43 offset fit on my '07 A3 S-Line? I think the 5x112 size is the same, but the offset is a little off (?)

Thanks!

Probably. A 43 mm offset wheel will be 1/2" farther to the outside than stock 56mm offset Ronal wheels. Using 224/45-18s might just clear if you're not lowered, and you may have to remove the fender liner screw at 12:00 in the front.

You can also install 'crash bolts' on the front struts to add a degree or so of negative camber that will give a little bit more clearance. Crash bolts will likely give you better turn-in and more front 'stick', but at the expense of tire wear and a tendency to rotate under drop-throttle in a corner (power-off oversteer). Unless you're an autocrosser, I'd avoid that.
