Launching harder, reducing wheel hop, and adding cornering consistency to your 1999-2004 Mustang is easy with lower control arms from BMR Suspension. Stock stamped steel control arms with soft rubber bushings deflect under load and absorb power instead of transferring it to the tires. BMR?s polyurethane, non-adjustable tubular control arms for New Edge Mustangs (TCA015) are manufactured from heavy-duty 1 5/8-inch DOM steel tubing. This design gives you a strong control arm that greatly improves performance. The integrated spring perch is built from heavy-duty plate steel for loads of strength. Greasable, 95-durometer bushings add a solid, more responsive feel over the stock rubber bushings. BMR?s bushings are internally fluted, which allows grease to evenly coat the inner sleeve. These flutes also direct grease to the outer edge of the bushing, keeping the thrust surface lubricated. This efficient lubrication ensures quiet, reliable operation over the life of the bushings.
