Give your pony some backbone by installing Stifflers brand full length subframe connectors from Innovative Performance Technologies. Engineered to be the stiffest, lightest and easiest to install weld-on subframe connectors on the market today. Due to its one-piece design and pre-masked welding areas, installation is quick, with no extra gussets to weld or powder coat to grind away! Stifflers greatly reduce the inherent flexing and twisting motion of the unibody experienced during hard acceleration, cornering, braking and road inputs by adjoining the front and rear subframes. Eliminating unibody movement allows the suspension better control and puts more horsepower to the ground. Get the most out of your Mustang, go with Stifflers!
