Launching harder, reducing wheel hop, and adding cornering consistency to your 1979-2004 Ford Mustang is easy with upper control arms from BMR Suspension. Stock control arms with soft rubber bushings deflect under load and absorb power instead of transferring it to the tires. BMRs polyurethane, on-car adjustable tubular control arms for Mustangs (UTCA015) are manufactured from heavy-duty 1 5/8 inch, 0.120-inch wall DOM steel tubing. The center adjuster is CNC-machined from chrome-moly steel with rolled threads for the ultimate in strength and durability. The arms feature TIG-welded chrome-moly tube adapters. This design gives you a strong control arm that greatly improves performance. Spherical bearings offer the highest levels of strength and articulation. When the highest levels of performance are required, BMR uses heavy-duty Teflon-lines Viking Performance spherical bearings.BMR Suspension designed the UTCA015 to work well in street performance, drag race, and road race applications. The stock control arms flex under even light cornering loads giving you inconsistent handling characteristics. Combine this with soft bushings that have massive amounts of deflection and youre left with poor performance. The UTCA015s heavy-duty construction eliminates control arm flex, giving you much improved repeatability on the street, starting line, or in the corners. BMRs spherical bearings offer tons of articulation for great handling, whiles remaining strong enough to stand up to high loads of any performance environment. These are the perfect upgrade for the enthusiast looking for max performance at an affordable price.
