E30 Zone

Just building my m52b30 and was wondering where is the best place to get main,bottom end bearings and piston rings from ?.is it best from main dealers or motor factors .car is going to be used for track days so it's going to get some stick .

I'd go genuine brands, but shop around for who has them at a good price, some after market guys sell genuine, which you probably already know.

I live in Australia and I never go to BMW here unless I can't get it elsewhere, cheers.

Turner motors port, ECS tuning and fcpeuro I believe all sell them.
