weird issue with my f82

PapaSmurff82 · 03-23-2018, 08:04 AM

under hard acceleration, the rear seems to rattle really bad. I'm not sure why it only happens under hard driving. I have a 6 mt.

I had the same issue. Its so common that BMW has a service bulletin for it lol. The parking brake lines apparently hit/touch the driveshaft under hard acceleration.

Car exterior rattle or interior?

If it's not due to the service bulletin, then you could have a bent rim; also if you're lowered you might have an issue there- I had a similar issue on my lowered S2000 and the fix was drive shaft spacers, and it road perfect after install. I haven't seen this on the forum yet so this would be the last place I'd look.
