Hey guys im new to the forum, and also new to setting up torque arm suspension.
The car is a 2000 Camaro. LS1 w/ nitrous. 6 speed manual, ford 9". 4.30 gear, 28x10.50 weight is 3300 with driver.
Strange coilovers on all 4 corners.
Adjustable lower control arms, adjustable torque arm, adjustable panhard bar,and an anti roll bar.

My question is, how do i find instant center on this style suspension.
is there a formula i can follow?
