It looks good without the bars. I assume you prefer the bars for a safety margin. Like Mike says, I would go tight on the compression, and about middle on the extension on the front shocks and start there. I assume your bars are directly on the rear end; ie you do not have a four link to attach the bars to. Without the four link, when you get tighter on the converter just prior to launch, the bars move down. Mine are considerably higher than yours. I started @ 14" to the center bolt, and raised them to 15" trying to stop the front end from coming down and I was also getting a momentary unloading of the tires. Just enough unloading to demolish a trans last Friday night. I am going to lower the bars, but I am going to soften the springs on the bar itself so it hits and rides and does not push down so early. My car is a 68 Cuda with a 500 in low hp/high torque motor about 3400 lbs and runs 10.20. 1.40 60 ft. We have another car that is a Duster T/STK car and it is a 9.50 car small block 600 hp. We normally are about 13" to the middle of the bars, tight compression, and adjust the extension to suit the track on the front shocks. We are not at minimum weight, and when we are really desperate, we take the bars off and have total control with just the shocks. We have Cal Trac system. 1.26 60 ft 2900 lbs. These have worked for us, but the GM suspension might be different on the rear.
