you cannot be a penny wise and a pound foolish when it comes to parts. You're not in the position to buy a new clutch every month or two (not to mention pay to have someone put it in if you don't do your own work). So, you have two options: expect to buy new clutches (because you're going to burn them up if you're a "regular" at the track) or don't race. I don't mean to be a dick, but you need $$$ to race.
