The best way I have found for big slick cars is to plumb the line lock into the rear wheels. When driving out of the water box, push the button in and hold it before hitting the brakes. This blocks fluid from going to the rear wheels, then you can apply as much pressure to front brakes as you need to hold the car. When done with the burn out let go of the button and roll out. This takes away all the wear and tear from the rear brakes on the burnout. Works great for me have had it like this on the last 3 cars.
