Sure, man. I had M3 offset bushings in before so the geometry won't be different, but hopefully they're worth it in terms of sharpening things up. IMHO, I'd go with the Bimmerworld "TrackCABs" because the paint job on the Treehouse ones are ****ing horrible. They came in all banged up. I'm not the first person to have this complaint if you read reviews on them. They're also a few bucks cheaper than the Treehouse ones too.
The only reason I didn't was because I ship to a US address and have my parcels forwarded to Canada. Bimmerworld wouldn't accept my order because of that and I'm not paying UPS brokerage fees.
