Pedders 2010 Chevrolet Camaro Suspension Evaluation- Page 5 - Sub-Frame Bushes

Continued from Page 4

There is a noticeable rear end step out in turns while applying power or brakes and dealing with bumps in the 5th Gen. This is due to the voids in the OEM Sub-frame bushes. It is not unique to the Camaro. It is typical of IRS systems installed with rubber bushes to isolate the passenger area from road noise. The larger and stickier your rear tires the more pronounced the sub-frame movement becomes. The same is true with increased RWHP.

The Camaro features much larger sub-frame bushes than the G8. These were improved to handle the higher loads created by larger rubber and high RWHP found in the Camaro. While they are an improvement, we do not feel they are stable enough for the way we drive a Camaro Sub-Frame Bush Inserts EP1200

Camaro so we designed two solutions.

Pedders EP1200 Sub-Frame Inserts are good up to 500 RWHP. The inserts fill the OEM voids in the rubber sub-frame bushes from both the top and bottom. The control surfaces are dramatically increased. Since the OEM bushes remain in place, this is more than just a great upgrade. It is relatively easy to install the EP1200. These eight pieces transform your Camaro and are probably the single biggest bang for the buck modification you can make.

For those taking the Camaro beyond 500 RWHP, drag racers and hard core corner lovers the best solution will be Pedders EP1201 full urethane Sub-Frame Bushes. With these robust bushes installed and well over 500 Camaro Sub-Frame Inserts EP1200

RWHP your Camaro will launch cleanly and track true under load. In these photos you can almost feel the improvement in performance. For ease of assembly there is a 3/4" OEM ferule holes through which a 14mm bolt is passed. Those sloppy OEM ferules are replaced with Pedders and holes suited to the 14mm bolts used to secure them. This change means there is no possible movement in the assembly under any load that doesn't bend or shear a sub-frame bolt. The increase in control surface is nothing short of MASSIVE. Your rear sub-frame will now follow your Camaro and not attempt to steer your Camaro. Switch backs are tamed. Drag launches are harder and crisper with a more efficient transfer of power. OEM and Oedders Sub-Frame Bushes

For ultimate in IRS control Pedders has developed the EP1201HD. Racers use Delrin bushes machined from stock. These are hard plastic suitable ONLY to a race car. They require frequent replacement. Pedders EP1201HD is a urethane of high dura that when captured by the Camaro sheet metal performs like Delrin, but has the durability of all Pedders urethane products.These bushes do transmit more road noise than the EP1200 inserts or the EP1201 full bushes. EP1201 Sub Frame Bushes with OEM In the Pedders USA, LLC Camaro we barely notice a difference because the aggressive tires we run. The EP1201HD is not a typical Pedders bit. It is designed for ONLY the most dedicated enthusiasts. In the video, you will see that there is NO visible sub-frame movement, even with a 3 2 downshift with wide open throttle.
