Hey All,
I was cleaning up and checking my mag race wheels yesterday and found some cracks! Basically this means I now have a VERY expensive hose reel for the house.
However I am glad I found the cracks this way rather than out on the track! The cracks started from a hole with a cover over it on one of the spokes (see the pic's). Once I removed the cover to clean them the cracks were very obvious.
Bottom line is check out your equipment well now. Before you find out you have a problem the hard and painful way. It really sucks that now I have a big ticket item to replace before the season starts, but that's racing.
