I just bought the DMS LCAs and brackets. which of the three settings on the bracket is best for traction?

 

Start with the bars parallel to the ground. The lower the rear of the LCA is, the harder the tires will hit. Too much can be as bad as not enough. It's a trial and error adjustment that depends on your car.

 

The lower control arms don't do a whole lot for traction on a 3rd or 4th gen. The torque arm is what takes most of the heat of planting the tires. The control arms will help a little, though. Here's what I've read on the subject since installing my BMR LCA Relocators. The top hole is same as stock naturally, the middle hole is for improving traction with a stock height vehicle, and the bottom hole is basically for lowered vehicles only to correct for the control arms being angled upward at the back after the car was lowered. The trick is to have them angled slightly downward at the back so that when the rear diff tries to turn the opposite direction of the tires, it will push them down, helping to plant the tires. If the control arms are angled upward at the back, when the rear diff tries to turn the opposite direction of the tires, it will lift the tires off the ground instead.

 

thanks, ill keep you guys posted after I go to the track
