is there a clutch guru in the house i have a ppp spring in my primeary(30 preload,3.0rate,128 force)what will be the affect if i put in a ysy spring(35 preload,2.5rate,118force) :confused:
 
how is total force figured? the reason im asking is my engagement is 3500 giving real slow throttle, giving faster throttle engage drops to 3100 my wot in 1000 ft is ok and im runing the ppp with two 40 tho shims i would like it to be 4100/4300
