  1. RACING coilovers adjust height by screwing into or out of the lower mount. Other types of coilovers, like Pedders OLD eXtremes, use the lower spring perch to adjust for height. This creates a litany of issues in car set up. The most critical is the lower you set the vehicle the less jounce / bound travel there is. This adversely alters ride quality. Lowering the car decreases the pre-compression on a coil. Raising the car by spring perch increases the pre-compression on a car. Having uneven coil pre-compression at each wheel after corner weighting in not desirable for optimal setup. Pedders Xa and Supercar coilovers adjust ride height like a RACING coilovers screwing into or out of the lower mount while preserving coil balance, and ride quality.
  2. Some brand-x coilovers do NOT use OEM mounts for their coilovers. An example would be removing the rubber bush from the rear upper spring perch and converting it for use as the load bearing point for the rear coilover. The shock bush in the Camaro upper spring perch was not designed or intended to be used as a load bearing point for the rear spring. ALL Pedders coilovers use the OEM mounting points.
  3. Inverted coilovers require maintenance. What cause failure of the shaft seal? Dirt. Debris. Abrasion. In an inverted coilover the seal shaft seal is pointed down to the pavement, mounted in the lower control arm. The most delicate wear component is exposed to the harshest operating conditions with an inverted design. That is why inverted coilovers are best suited for track use -- limited exposure and miles. Does your customer want a coilover that requires seal maintenance? Does your customer know the inverted coilover seals require routine maintenance? Can ANYONE tell the customer what the expected shaft seal life will be for an inverted coilover on the street? The answer is no. Do they drive down dusty roads? Do they drive near the beach where sand blows on the road? Do they drive in the rain? It will be different by customer depending on driving habits, road conditions, climate variables and more. NONE of Pedders coilovers are inverted and do NOT require routine maintenance like an inverted coilover.
  4. The clevis on Pedders Xa and Supercar coilovers are 10mm wider than OE to allow for increased negative camber range WITHOUT any additional parts. This also help balance the front and rear track to reduce understeer
  5. RACING coilvers have independent bound and rebound adjustment. If you are a racer, if you are a wannabe racer, if you autocross, if you drag race, if you are an enthusiast you want a coilover to be able to adjust, to tune your Camaro. The hands down class leader for the Camaro is Pedders SUPERCAR coilovers. It adjusts height by screwing into and out of the clevis. It has bound adjustment. It has rebound adjustment. It is not inverted. It does not require routine shaft seal maintenance. It has 10mm of extra clevis width to allow for great negative camber. Pedders Supercar Coilovers have independent bound and rebound adjustment.
  6. The bigger the piston diameter, the smoother the function. Pedders Supercar coilovers are 52mm. Our Xa range and most coilovers on the market are 46mm. The larger the diameter of the piston, the larger the volume of oil the SMOOTHER the control will be. This is a rule of fluid dynamics. Pedders Supercar coilovers will deliver the smoothest, the best possible ride quality you can get out of a Camaro. Supercar coilovers will be a superior ride for the owner to OEM because of the fluid dynamics and independent bound and rebound adjustment.
  7. Pedders Supercar Performance, alliance with GM and GMPP make Pedders the Camaro leader. Every GM owned Camaro at SEMA 2009 was on Pedders. Jay Leno's Camaro is on Pedders. All the 2010 NASCAR and INDY Camaro Pace Cars ride on Pedders.

These are the facts and nothing but the facts.

Issue #1 is what I'm running into with the Pfadt's. Also, #2 is a problem because I had to remove the rubber bushing for the Pfadt's.

Would you happen to know the part number for the rear upper rubber bushings?
