Gach To back up your numbers a friend of mine has an 83 camaro with stock design suspension (torque arm). He has Spohn
components under his car. Last year he went 9.38 @ 146 on drag radials. He did a few things to the car already this year. Should be in the high eights. the way this car hooks and launch's is un real that is what has me interested in this suspension set up.
rear axle to with torque arm set up = 2000
adjustable spohn torque arm = 400
double adjustable lower control arm = 250
lower control arm drop brackets for anti squate = 85
double adjustable pan hard bar = 200
anti sway bar = 370
coil over shock of choice = qa1 = 400
s&w direct fit rear frame rails for coil overs = 190
custom front connection point of torque arm = 50
custom front connection point of lower control arms = 50
total rear suspension = 3995
this is bumping everything up. yeah it is expensive but if you take out the 2000 for the rear, it' isn't that bad. and for some one who can fabricate it will be cheaper yet.
