its here!! rob made me a psk just for the c3 users. i installed it last week and so far it works flawlessly. my goal was to eliminate the pulleys that keep failing on me and this is the real deal. install was easy and the no more grinding bearings!
heres a video and a couple pics

my impression is the tensioner is a bit over halfway on install but as it stretches it should loosen a tad. spoke with rob and he thinks it will be fine. not as much belt wrap on the c3 as hoped but it will do for me.
if any c3 users want this simply contact needswings and they can hook you up!
thanx rob for being patient with me and woody for his great ideas.

300+ miles som far with no issues. some hard launches along with a few high speed runs (140mph+) and it just purrs!
