Launching harder, reducing wheel hop, and adding cornering consistency to your Third or Fourth Gen GM F-body is easy with adjustable 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. BMRs poly/rod end, on-car adjustable tubular control arms for F-bodies are the ultimate is strength and adjustability. Manufactured from heavy-duty 1-inch, 0.120-inch wall DOM steel tubing, the TCA004 poly/rod end lower control arms nearly eliminate all control arm deflection. TIG-welded chrome-moly tube adapters with a center-mounted adjuster make on-car adjustments simple and easy. Greasable, internally fluted, 95-durometer bushings add a solid, more responsive feel over the stock rubber bushings. BMRs bushing design allows grease to evenly coat the inner sleeve, keeping grease in the bushing under high loads. 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. The other end features zinc-plated, X-series, heat-treated, chrome-moly, self-lubricating, Teflon-lined rod ends. It also features 304 stainless steel, custom designed rod end spacers.The stock control arms flex under cornering loads giving you inconsistent handling characteristics. Combine this with soft rubber bushings that have massive amounts of deflection and youre left with poor performance. The TCA004s heavy-duty construction and polyurethane bushings combined with heavy-duty rod ends eliminate unwanted deflection, giving you much improved repeatability on the street, starting line, or in the corners. BMRs polyurethane bushings are compliant enough to give you a comfortable ride and absorb NVH, while remaining firm enough to stand up to high loads of any performance environment.
