Default Which clutch for track use?

I have done some searching, and looks like no easy answer yet.

Is there a clutch replacement for our GT3s that is more durable for track that has risen above the others?

Car: 2010 GT3 997.2 non-RS with 4.0 LWFW and pulley, 14,000 miles, at least 2/3 track, not used as a street car at all. Also need new clutch actuation arm (fork) as well--somehow (not obvious on inspection) this one has an unusual gouge in it.

Thanks for any help. Transmission apart now.

First 1/3 was non-track, last 9-10,000 track; now all track, no street, ..., if that changes recommendation.

I have ERP double carbon and is great on the street, was worried it would be too abrupt. Tilton is good except I've heard hydraulic TOB is a week point in the Tilton metal or carbon setups... For track, Tilton or ERP, they can take the compressive stress of less than perfect rev matches better than the OEM...

Hardcore track use is going to require clutch maintenance regardless of what you use.

I think the carbon clutches have certainly become more "streetable", but you just shift the wear/stress to other components, when using rigid hub discs and high grip disc materials. The gear stacks, throw out bearing, and clutch release fork take more abuse, and the release forks are already becoming culprits in more and more clutch related issues.

I just replaced my clutch with the OEM .1RS setup, but I believe the aftermarket segment for these cars will continue to grow, as it always does when cars become older. Hopefully by the time I need a new clutch, more products will offer a solution which addresses the additional wear concerns, rather than just adding ultimate clamping force as the fix.

We spend $$$$ on tires, brakes, motor and gear oil changes every 6-10 days, but then expect a clutch to last a lifetime. Doesn't work that way.

They offer flywheels, and if I remember correctly, their kits use the stock Sachs throw-out bearing. ERP is a nice setup, no doubt, but not cheap either.
