With the Pfadt Camaro Solid Subframe bushings you can completely eliminate subframe movement. By solidly mounting the rear subframe you will find that the car feels more precise and reacts to your steering inputs more quickly. Drag racers will find that their launches will be more controlled and wheel hop will be drastically reduced if not eliminated. When launching the car before we found that the subframe would violently oscillate and cause a drastic reduction in traction. Now with the solid subframe mounts the launch is substantially smoother and more controlled. Auto-crossers and road-racers will find that the rear end is more controlled and the car is far more stable and predictable. After the installation of the solid subframe mounts the chassis and subframe are no longer acting as separate structures so the rigidity and strength of the rear subframe and chassis is also improved. One of the common concerns with mounting the subframe solid is noise, vibration and harshness in street application. We are excited to say that this product is very acceptable in each area. Because the control arms and differential are still isolated from the chassis the noise and vibration increase is minimal and is a great street upgrade. The Pfadt Solid Subframe mounts are precisely machined of 6061-T6 aluminum and lightly press into the subframe for an easy and secure installation.
