I have an 02 viper er . mods are : hartman 136" tunnel exstension,1.250 track ,rear heat exchanger,bender tripple pipes,head mod,air box mod,24/38 gears,162.5 jets. sled is very fast and reliable, but clutching would bring it all together! I have a set of heel clicker weights from a viper kit, but need to know what weights,shims,and spring i should use inthe primary. what helix and spring in the secondary?

4 grams heel , empty middle, 4-5 grams in tip, red primary h/c spring, no shims, secondary clutch run a 50/40,48/40, or a 50/38 helix with a green spring around 70-80 twist, test for rpm and post results we can fine tune from there.
