help with suspension setup
I have a stage 3 permabuilt 4l60e with a Precision Vigilante 3400 stall and strange 12 bolt rear end. 150hp plate kit, and the rest of bolt on you can have.
I would love to set it up to have a killer 60ft but still be able to drive it comfortable on the street.
On the rear I just switched to the strange single adjustable with BMR springs. I haven't ran it at the track yet. For street use I run the middle setting. I used to run stock springs with comp 3 ways set at 50/50. Best 60 on motor was a 1.48 last season and 1.51 this year. I'll let you know if the strange shocks helped and how I set them if the rain hold off Sunday.
Rear control arms are set in the middle hole and pinion angle is at -2*. Depends on how low the rear is but I asked the same question recently and was told as long as the control arms are running downhill from front to back you should be fine. I have no complaints on the street.
I'm in the testing stage with mine so if I find anything that works better I'll pass it on.
When I was running stock springs and comp 3 ways it would pull the front 6 inches or so and went 1.52-1.53 on motor. It's too little a difference for me to say that it wasn't track prep, weather, tire pressure, weight difference, etc. So for now the settings I listed earlier should be just as good as what I had and a good starting point to work from. Try those and see what your car likes. You may need different settings on the rear shocks since the BMR springs are a little stiffer than your stockers.
