430 scuderia warm clutch problem

Hi

On my scuderia that I use on the track and fast road there is sometimes some short clutch slippage when warm when shifting at full throttle and high rpm from for example second to third gear.

I know it s probably the clutch that should be changed because used or glazed but it really
makes it only when warm and driving fast on the track and was wondering if something else could cause that as clutch fluid or f1 pump or other as when cold the clutch seems to bite really well and shift well and fast.
