There are plenty of good clutches for $250.00. Just be aware of the 9 14" kits that turn up lately. I bought a clutch kit for just over $100.00 on a close-out deal that is giving stellar service.
All clutch kits have their origin in the original Valeo clutch that was standard in the SHO. It is a nice compromise between long life and performance and I think they got it just right.
All variations of the original, center around altering the pivot point of the clutch fingers which affects life duration.
The Throw out Bearing eating through the pressure plate fingers is the single biggest reason for having to change a clutch. Not a worn out clutch disc. I have never worn a clutch disk out, but I have changed lots of clutches.
Towards that end, my last kit install included a Ceramic Throw Out Bearing (TOB) with the hope that it will last longer.
I am not saying the Clutch Master series, or any other series is a bad idea. But because of the labour costs and aggrivation associated with a clutch change, I am thinking how long will the system last when I pay the bill. If that is not a concern, there are plenty of radical clutch systems you can choose from.
