Recommend 5mm spacers for track

Hey Bimmerpost fam, can anyone recommend quality 3 or 5mm spacers that I can safely run on track? I'm fairly certain the front EC-7 wheel will need some clearance from the M Performance suspension.

Thanks

I use 5mm spacers by Turner, tracked numerous times... no issues.

By far, the best "thin" spacers are the Turner ones. They have a unique design that leverages the scallops in the hubs to provide full hub centric support. They are more expensive but well worth it.

I run Apex with no issues https://www.apexraceparts.com/accessories/spacers.html

Maybe it's just the 666M wheels, but I have a hell of a time getting the wheel to rest/balance on the hub without spacers, let alone with. Not sure why BMW altered design from E9X gen. Stud kit with spacers makes things a whole lot easier.

Agreed. The Turner design looks superior.

2.5 lbs., not bad... I'd take 2.4 and E9X style mounting positivity.

I've been waiting on those 5mm extended ones from Turner for months lol! I had 5mm BW ones that were only going to be used for street due to the non-extended lip design. I finally quit waiting for the 5mm and just got the 7.5mm extended ones from Turner and like the additional room they gave me off the strut compared to the 5mm. They made my 437m's look way better!
