Launching harder, reducing wheel hop, and adding cornering consistency to your S550 Mustang is easy with polyurethane bushing vertical links from BMR Suspension. Stock stamped steel vertical links with soft rubber bushings deflect under load and absorb power instead of transferring it to the tires. BMR?s tubular, poly bushing vertical links (TCA048) are manufactured from 0.75-x1.5-inch steel tubing. This design gives you a strong vertical link that greatly improves performance with zero deflection.
