Once you install all the parts and have your sled set up, take note of all the clutching specs that you used and post them on here. This is a helpful board, and the people here will help you get your sled running at its best, they will also help you fine tune your clutches if you describe to them what it is doing. This generally can not be done when you use an aftermarket "kit" due to the fact that these companies will not release and of the specifications of the parts used. I guess this may not apply to heavy hitters, heel clickers, etc. as i have read many good reviews on these products and most people seem to have very good luck with them.
