o.k i thought i would make a POST FOR setup and issues that almost everyone has with caltrac..also a place to start from for the first run/test pass along with how to adjust after you have a few passes. start at the front and make sure the front control arm are not binding. this is one of the biggest issues. you can do this with after market bushings or control arms or just elbow grease. the control arms should fall on there own without having to push them down. the front springs need to be of a drag style that will give you the best weight tranfer you can AND MUST HAVE ATLEAST 5" OF UPWARD TRAVEL IN THE FRONT END. shocks should be of a good drag style i like d/a afco's. AFTER DOING ALL THE ABOVE SET THE SHOCKS AT FULL LOOSE FOR THE FIRST FEW RUNS. FOR THE REAR same thing binding is the number 1 issue most the time it's in the shackels and the front leaf spring mounting bolt.. every car i see the bolts are over tightened you should be able to push the rear down 5-6" easy without the shock or caltrac mounted. lube all bushings well and don't over tighen. know that theres no binding, any adjustment later will work.. i always start in the upper hole and preload of 1/16 gap. this will give you a lot of pressure over the rear tire. shock settings ON REAR, i always start at full tight on extension... know that the car is setup for a test pass have someone video it.. THE CAR WILL DO ONLY A few THINGS NOW. IT WILL HOOK AND PULL A HUGE WHEELIE, IT WILL HOOK AND DO WANT YOUR NEED, IT WILL HOOK AND pull left or right, IT WILL HOOK AND SPIN 20FT OUT...IT WILL KILL THE REAR TIRE BY HITTING IT WAY TO HARD IF YOU HAVE DONE EVERYTHING UP TOP I'M 95% SURE IT WILL ONLY DO ONE OF THESE THINGS.. IF IT HOOKS AND PULLS A HUGE WHEELIE THEN TIGHTEN THE FRONT SHOCKS THIS SHOULD BE THE ONLY REASON TO TIGHTEN THE FRONT SHOCK....IF IT HOOKS AND PULLS TO THE RIGHT OR LEFT THEN PUT A LITTLE PRELOAD ON THE SIDE IT PULLS TO.. IF IT HOOKS AND SPINS 20FT OUT START LOOSENING THE EXTENSION ON THE REAR SHOCKS 1-2 CLICKS AT A TIME TO IT HOOKS AND STAYS ON THE REAR TIRE.. IF IT KILLS THE REAR TIRE YOU NEED TO PUT THE BARS IN THE LOWER HOLE AND ADJUST THE SAME AS YOU WOULD IN THE UPPER HOLE. IF YOU HAVE LOWERED THE CAR A LOT THERE OTHER TRICKS TO DO BUT FOR 98% OF THE CALTRAC CARS OUT THERE THIS WILL BE ALL YOU NEED.. if your running a dragradial with big power and a 2.3-2.5 fisrt gear ratio in your trans and a rear gear taller then 3.60 good luck!!! you will chase you tail for ever..
