How much shipped? [ http://www.pstds.com/ ] I've been interested in this too, I loved the flywheel, and looking forward to the Fisher pully, and this seems like it has the potential to make the most difference. They use their carbon fiber drive shafts on their 7.4 second mustang drag car...seems like they are tring to say they are pretty sturdy. I didn't see anythign abotu a warrentee though. Eitherway, what price are they quoting you?
