The same is not true in the rear suspension. The upper rear control arm bushes are relatively soft and highly compliant. We feel strongly they should be replaced with Pedders
EP7322 Urethane Upper Rear Control Arm Bushes. These higher durometer bushes control the loads generated by an enthusiast behind the wheel of a 5th Gen. With the upper rear control arms and sub-frame Pedderised, we move to the Toe Link, Trailing Arm and Knuckle Bushes. All of these will benefit from Pedders EP7323 upgrades. This is how Pedders delivers track like handling with OEM like ride. We take a little compliance out here and a little there. No one part is doing all the work.
A lot of incremental upgrades deliver a driving experience that is far greater than the sum of the individual parts. The only control arm weakness left to address is the inner rear control arm OEM bush. We upgrade that to a Pedders EP7264 Steel Jacketed Urethane Bush. The rear suspension is almost fully Pedderised at the foundational level.
The last element is the differential. The ZETA II differential is mounted with three steel jacketed rubber NVH voided bushes. The Camaro has a long history on the track. It covers
both strip and road course. While the overall setups for these types of cars are different in many ways, a stable differential that efficiently delivers power is common to both. Pedders addresses this need with a set of three high durometer urethane bushes in our EP1167kit. The EP1167 works extremely well up to 450 RWHP. You'll experience crisper launches and stronger shifts with the EP1167 installed. For those who like Pedders choose to build their Camaro well past 450 RWHP our EP1167HD is the solution. The HD version
does not have the voids found in our Sports Ryder version. The durometer is higher, for the loads delivered by higher output engines. There is a difference in cabin noise level with the EP1167HD. This is directly related to the elimination of voids and the increase in material hardness. It is a trade-off for ultimate performance with Delrin like performance, but with Pedders durability. Even if you run OEM spec power, but you hit the track HARD, you'll find the differential bush upgrade allows you to have a finer edge of control in the application of the loud pedal.
Caution: Test driving any Pedderised vehicle can be dangerous. Pedderised vehicles have been known to induce suspension envy and sleepless nights filled with longing. Before test-driving any Pedderised vehicle, check with your banking and accounting professionals. Pedderised vehicles are known to induce credit card bills and reduced bank balances. There is no antidote. Only genuine Pedders can cure Suspension Envy.
