You are unlikely to need an uprated clutch.
Stock ones last for fairly huge mileage and the only difference is in resistance to heat (plus the uprated ones may not last as long, as competition cars replace things like this more often).
The clutch you have must be able to transmit all the power of your engine. If not, then when pushing to this level you will simply be wearing out the clutch. If this is not happening, then the clutch will not be wearing out except when you slip it and only will heat up while that's happening. Rarely an issue. But the clutch must be able to transmit the engine power, you only want the clutch to slip when you want it to. Which is all about peak engine power.
