I suffered catastrophic wheel damage and needed to get replacements quick. I found a very cheap solution with OEM Audi wheels - A5 wheels. 18x8.5, ET29. That's 1mm difference in offset! They won't be the lightest wheels but they're factory OEM and for $98 a piece shipped I think I won on the quality vs price ratio.

Gears turning in my head, and someone mentioning that there is a LOT of space in the rear...how about a staggered setup? Stick with 18x8.5 up front, but go 19x11 in the rear with 295/30 R19 tires? Who knows with real world variations between brands, but theoretical tire calculators show only a very minute difference in rolling circumference and diameter between stock sized 255/40R18, and 295/35R19. If it fits, that'll be pretty cool. I do have to wonder about what effect that would have on handling. Would it worsen understeer?
