Ok as we all know reducing rotating mass is a good thing and I think we all understand its benefits.

My quetion is plain and simple. Has anyone put on Rick's Billet Pulleys on their s2k?
Has anyone had any balancing problems, mechanical or any other issues with these, or is this just a useless mod to stay away from (unless you wanted that Bling factor)?

 

Contact "Fongu", who has these. He's in Ottawa, so not far from you. He and I have had discussions over the technical merits of such a mod.
