McLeod clutches are, hands down, the best I've used. Give them a call and they'll set you up with a clutch to fit your needs. I got the basic single-disc street clutch, pressure plate, and steel flywheel, and it held 308 RWHP with no problem at all. 100s of track passes and my daily driver, and it's got 35,000 miles on it now and still going strong. A buddy has their twin disk setup and loves it compared to others he's tried. He upgraded to their ceramic friction material recently to hold his 636 RWHP setup. So far it's working perfect and still engages smoothly.
