Stock stamped steel control arms with soft rubber bushings deflect under load and absorb power instead of transferring it to the tires. BMR's non-adjustable tubular control arms for 2008-2009 Pontiac G8 (LCA357) are MIG-welded and constructed from DOM steel tubing, with laser-cut mounting plates. This design gives you a lightweight, strong control arm that greatly improves performance. BMR's Poly bushings add a more responsive feel over the stock rubber bushings. BMR's bushings eliminate bushing deflection, ensuring more power get to the tires.BMR's suspension designed the LCA357 to work well for street performance and drag race applications. The stock control arms flex under load giving you inconsistent launch characteristics. Combine this with soft bushings that have massive amounts of deflection and you're left with poor performance. The LCA357's lightweight, yet strong construction eliminates control arm flex, giving you much improved repeatability on the street or starting line. BMR's poly bushings eliminate bushing deflection and transfer the maximum amount of torque and horsepower possible. This means better throttle response, quicker 60-foot times, and improved all-around performance.Trailing Arms (TCA033)Launching harder and reducing wheel hop, on your 2008-2009 Pontiac G8, is easy with trailing arms from BMR's suspension. Stock stamped steel trailing arms with soft rubber bushings deflect under load and absorb power instead of transferring it to the tires. BMR's spherical, non-adjustable trailing arms for G8s (TCA033) are manufactured from heavy-duty 1.25-inch DOM steel tubing.
