Get your flywheel balanced.

I’ve had pretty poor luck with Clutchmasters products, both in my own cars and customers alike. I just don’t use them now. I’ve also experienced near exact issues as Paul did with Fidanza with non fitting flywheels and BS remedy suggestions from the company. :wierd The only aluminum FW’s I use now are the 930-993 KEP single mass replacements, other than that it’s steel or nothing.
