I recently upgraded the wheels and ended up with 2 full sets (20 pieces each) of lug bolts from my A4. They're 14x1.5 thread pitch and 28 mm long. These are the OEM lugs. One set is the ball seat that works for Audi OEM wheels. The other set is ball seat too but uses an adapter to convert from conical to ball. VW wheels tend to use conical. They're just sitting around, so if you want to paypal me some $$ to put them in a box and ship them, let me know.

I'm in San Diego, CA (92037). So shipping will vary, but my guess is something like $10-$13.

Thanks,
Matt
