Hey! That Sounds Great! It's Something It Wouldn't Do Before. It's Been Awhile Since I Drag Raced An Automatic. Is It O.k. To Let The Rears Spin? The Fronts Are Holding The Car. 1000ft-lbs Of Torque? Cool. If You Want The Rears To Hold, Also, Then We Have To Increase Caliper Size. Adjustable Prop Valves Only Turn Down Pressure, Not Up. The Rear Caliper Pistons Need To Be Larger To Clamp The Rotor.
