I bought a SUV to tow my track car around and will not be driving my M3 in the winter. I sold the tires from my winter setup to a friend. I have the rims to sell. The specs are below. They come with TPMS (currently mounted on the rims).
Beyern Mesh Silver:
18x8.5; ET30; 24lbs
18x9.5; ET30; 26lbs
The offsets work the way they are, but you could use 10mm spacers in the back to bring them closer to stock spec.
Pics of wheels on the car are here:
3 of the 4 of the wheels have curb rash thanks to the snow covered granite curbs (on the edge of the barrel--spokes are fine). Doesn't affect performance; wheels are straight as far as I can tell--no vibrations, etc.
Anyway, I don't really have the time to pack and ship this stuff, so local sale.
Keeping in mind the rims now cost $257 new each, and TPMS costs ~$180, ($1200 total new) I'm asking for $500 after discounting for the curb rash and used condition, etc.
