I have a 6 puck semi metallic solid hub clutch on my 3.4l Boxster which sees more street duty than track, and I hate it. I've demolished 3 axles so far on upshifts ( at DE events and autoX, not the street ), and traffic is brutal once the clutch gets a little heat in it.

My 951 is going to need a clutch soon, and its going to be something like a cup clutch disc and a kep pressure plate. Im not installing a clutch that will have my car jerking and shuddering in traffic while the clutch disengages.

I'd recommend everyone to choose their clutch wisely.

However, whenever there is an drag style start for an autoX... I do enjoy slipping the clutch out at 5000rpm on racing slicks without so much as even a complaint from the clutch...

Cant recommend Clutchnet as we had purchased 4 discs from them but they turned out not fitting an S2 as we asked for as the hub was too large. We tried many times to email them and even called them a few times and they were not interested at all in fixing the problem.
