Relief Valve

I know this was a issue on the Z4M coupe.

Anyone change this on the 135 or 1M?

A few people have. I've never had issue with it on my car though. In fact one of the smoothest shifting cars I've ever owned.

If you don't feel like you need it then I wouldn't mess with it.

I did mine a few weeks back, worthwhile and cheap (in fact free) mod, an easy DIY.

Sorry for the obvious dumb question, does it really change the shifting that much?
