Are the synchros from DD or FLP's site the Viper synchros? I migth be doing a buildup of my tranny. While I am there I might do a new clutch as well. I should currently be in the 380-400rwhp range, and I am running the SLP clutch assembly (stock disc + LT4 PP). I plan on throwing 4.5-6psi on down the road along with 12bolt. I need a clucth that will handle 500-600rwhp. What do yous recommend? I have done searches and found mixed reviews abou Spec, Cenetrforce Dual Friction, and Mcleod. I would like people's opinions based on their experiences. Thanks for the help guys. Also, any got a flywheel they like too?

 

Any opinions from the lunch crew?
