So how is longevity of aluminium drums? Do they get wear marks from steels inside? Whats your experience?

I only knew of a couple racers with alum drums. They said no problems with over 400 runs in 10 second cars. Mine had over 200 runs when I pulled the pan to have a look see. Pan was clean as a whistle. Kim
