Does anyone know how wide of rims the a4 will fit without modifying the wheel wells? I thought about a 3 piece offset rim.

 

8 with a 36-39mm offset. also depends on what size tires too. 235/40/18 is the largest i've seen people run without rubbing usually. of course each tire is a little different.

 

Yep different tire designs have different shoulder curvature. Mine are 19x8 and a +37 offset (+42 offset built into the wheels and I'm using 5mm spacers). The tires clear the suspension and spindles but only by a very small margin. I don't know if I'd go any more than a +38 even on a 225-section tire though just to keep a margin of error.

 

I'm running 19x8 as well, with 235/35/R19 tires. I used to have pretty major fender rubbing issues in the front (lowered on Eibach springs) until I got those fenders rolled. The back is/was perfect.

Not sure what offset the wheels have, I bought the car with this setup.

 

I'm also on 235-35ZR19 tires and I'm lowered 2.5" up front and about an inch out back on coilovers, and rolling the fenders is a must. But the offsets above will allow the combination to work. It's tight but it works.

 

18X9's all around.

Rub everyday.

 

Hahaha Krip, I'd love to see your tires. I'm getting some 17x8.5's soon so I should probably roll my fenders soon.
