I have had the time to try this 4 shoe clutch and for sure it is an improvement over stock.
I certainly believe that the stock clutch starts loosing performance when it gets hot and easily overheats on a high hp motor.
On a stock 23cc engine with a DDM side pipe and billet air filter it works great. Been there done that. My friend´s TT is also set up like that and works fine.
When the clutch gets hot, the spring loses tension making the clutch to grab early. Even the 8k spring. If you see that, stop the car let it cool and when you re-start it you will see that the clutch works fine again.
I highly reccomend this upgrade.
