I already have a 3 Step Revv installed along with a 3 Step Retard. All my electronics are in and installed. Not going to go after a new set up just yet.
The line lock will work without a doubt! Only difference on putting the solenoid in the rear line is it interrupts flow to the rear wheels so you can SMASH the brake pedal with your left foot as hard as you need to hold the car without engaging the rear brakes..... All my buddies have their cars like this and it works very well. Stick car.... You would be doing some fancy foot work. Lots of guys don't even use the line loc.... They just power brake it and let it fly.
