Spend the money and get a McLeod. It's expensive but when you break it down by pieces, its reasonable (remember, it comes with its own flywheel along with the clutch assembly). This is the clutch that HVAC uses and it has proven it's ability to hold up. The jury is still out of others like the Sachs, but as testing info comes in, it may work well also. There are mixed emotions on the Centerforce Dual Friction. Some have used it and lost it in 10 miles. I have had mine for 25000 miles with just a PowerMax2 and another 5000 with the PM2, VanAken, and 275 injectors.
If you have some mild hp upgrades, the McLeod may be overkill now but will allow you to make additional increases without having to replace the clutch again.
