These came equipped on my E90 328XI M-Sport. They estimated to have 8-10k miles. I don't know for sure. I replaced them. I didn't have any issues with them, I just wanted something less sporty and something more aligned to daily driving. They just need to be cleaned up. I didn't spend any time wiping them down.
Local pick up $350. Shipping will be considered if they don't move locally.
Serious inquiries should send PM.
Thanks
