It depends on what track you are driving on. At Daytona and Talladega, I use 3.5 turns of wedge and 30 psi in the tires. At Bristol and Martinsville, I use -1.0 turns of wedge and 22 psi. Use whatever you want, or try tinkering with the setups in practice 1 change at a time until your car feels right.
