You should have someone experienced evaluate how you're shifting. Are you comfortable on track? Are you sure you're not preparing for downshifting into a corner and riding the clutch with your left foot (applying slight pressure)? This could certainly overheat a clutch.

Again, I've tracked a bunch, never done anything to the clutch aside from high temp brake fluid and it's always been a rockstar.
