I can save you $$$$$$$$$$$. Ready, Alignment, offset, deflection, venting. Gear it down to M8 gearing or lower and switch to the 046 belt! The 060 belt is an exploding, crank busting POS. You are correct on the non-floating secondary, and you can align "at speed" using the black pen trick as others have done. Do all this before you start changing weight and springs and you will get results.
What is the "black pen trick" and how do you align these clutches?
