pinion angle
 

on my s10 w/leaf springs, i have 5* angle. should i keep this angle if i preload my slapper bars? or should i either let the bars come up to the spring on launch or change the angle to less than 5* and preload the bars? in the past i preloaded the bars and had 1.57 60' times, but now i've removed the lowering blocks and 1 spring leaf to lower it. the bars are the type you clamp to the springs instead of using the spring plate to mount them.
