Aluminum brake drums for GM vehicles

I bought a pair when they first came out from Kirban Performance/ Mike's Montes. They are a really nice piece. Worth the money.

I run those drums on both my cars. I was able to cut 2lbs of weight out of each drum.

I would be very careful running aluminum brake drums. I put a set on my car probably 15 years ago. I close friend that worked in a muffler shop told me they were noted for cracking on daily drivers and told me to keep a close eye on them. I pulled them off after attending a couple of races and both drums had cracks in the inner iron sleeve. You have an iron inner sleeve and aluminum outer, two metals with very different rates of expansion. I know of a fellow racer here in Div. 3 that had one shatter and put his car in the sand trap.
