How bad is this? ( Clutch Drum )

The car will be raced as much as time will allow :)
Im improving the engine alot with new rods and pistons and a new cam so i figure it would be unwise not to strenghten the trans :)

I have actually spoken to Chris Andrew via mail several times and was planning on giving him a call next week for new bands and dishes and everything else, but thanks for the tip anyway :)
