Track suspension setup questions
Track suspension setup questions I posted this in the suspension section, but posting here as well hoping to get a response.....
Im heading out to the track again tonight and I'm looking for some advice on improving 60 foot times.
Suspension mods are KYB adjustable front struts with QA1 275lb springs, UMI TQ arm, Spohn Panhard bar, and Lakewood Lower control arms with pre-load bars. Running M&H Racemasters 26x11.50x16 @ 12-14#
I had the car out a few weeks ago and the track was very cold and we were having issues getting traction on most passes.
Does anyone have experience with these lower control arms? I had previously put the car on the ground, installed the pre-load bars and then pre-loaded them so there was little squish in the rear, is this correct? I have considered raising the car and supporting the body and letting the rear droop and then pre-loading the control arms at that point, is this something to try?
Car has a best of a 1.64 60ft on motor, but I personally think it can do better. Any advise on setup/suspension is welcomed.

Haha thanks for trying, doesn't matter. During warm up idle the engine developed a knock, metal in the oil. Damnedest thing, ran great when the 60's were installed a week ago....
No preload on the LCA
To start, set the car up on level ground as if you are going racing with you in it wearing all your gear.
Then you want the LCA to be about 2 degree up at the front attach point. You will have to adjust the rear attach point so that the rear attach point is about 1/2" to 3/4" lower then the front attach point to get about 2 degrees.
Then disconnect the rear drag bar on the driver side.
Then if you have scales you would adjust the front left or right rear spring to have about 10 to 20 pounds more weight on the right rear tire.
Finial reattach the rear drag bar with no preload.
Go racing and make small adjustment to the rear drag bar to make the car go straight on the launch.
