I've always believed when it came to drivetrain components, you should shoot for over your targets, rather than under. I looked at the JWT setup for my TT build that's upcoming, but I was recommended by Joe@ZSpeed to go Southbend because of the torque holding capacity.

What did you find out as far as torque numbers for the 370 JWT?
And what does 1200kg of clamping force really mean?[/QUOTE]
My research cropped up lots of numbers, low as 350wtq or as high as 500wtq. But, I also considered another aspect of that rating which is very crucial - performance under duress. I glazed my previous clutch over due to me drifting the car and performing hard clutch kicks, as well as drag strip launches and power shifting the car. Even though I only made 305whp and 270 or whatever tq, the clutch couldn't handle the duress I put it under.
Hence why I went with the strongest, most driveable 6-puck offered by Southbend without costing a stupid amount of money like the twin-disc lineups or anything. Even though I do see the reason for the twin-disc setups and it's performance, my personal budget and requirements made me concur with Joe and I went with the Southbend setup.
