Most of you already know that Riley Tech has been selected as the EXCLUSIVE builder of the Camaro for the Grand Am Challenge GS Camaro.

What you don't know and I can now say that Pedders worked with GM on the development of this vehicle. The Grand Am Challenge Camaro will run the circuit using what Pedders considers to be daily driver bushes and bits. The OE Camaro will arrive with hydraulically damped radius rod bushes. The OE radius rod bush performs well on the street for most drivers. For the enthusiast driver a hydraulically damped radius rod bush is about as useful as the wrong size driving shoes. They are too compliant. GM asked Pedders to develop a radius rod bush that would withstand the demands of track use. You will be able to buy EP6560C Camaro Radius Rod Bushes, the same bushes we developed for the Grand Am Challenge. It is the same bush we will be using as a basic component of the Camaro suspension.

The Grand Am Challenge is a full on race car. It does not use street style dampers and there are other revisions to the suspension and drive-line. These cars will also be using Pedders eXtreme Castor Washers in addition to the full on hard mount strut bearing with Castor and Camber adjustment. In the rear suspension Pedders EP7267 Toe Link Bushes, 5422 Toe Link eXtreme Washers and EP7266 Rear Control Arm Bush. In testing at the Milford Proving Grounds GM determined that our Pedders Bits met or exceeded their engineering and driving expectations.

Pedders is a unique company. We do not make parts for race cars. We do make some street parts that just happen to perform incredibly well on the race track. Our warranty is also unique. Pedders does not have a racing exclusion. You can take your Pedderised street legal Camaro to the track, flog it. If a Pedders part fails within 24 months or 36,000 miles it is covered under warranty.

We were absolutely thrilled to be invited to work with GM on the development of the Grand Am Challenge GS Camaro. We consider it an honor to have been selected for such a special project. Working with http://www.rileytech.com/ is another honor. I can't even begin to imagine a better way to introduce Pedders to the Camaro enthusiast community.

This is some pretty promising information. Especially the ZR1 quote...I think that'll be going in the signature.

I'll only be there on Sunday, but I will have a ProCharged, Pedderised G8 with a Corsa exhaust for show and tell and probably a few test rides. It is a close as you can get to driving a Camaro unless your are a GM Project Camaro Staffer.

Any chance you could make it to the "Back at the Brickyard" event Sept. 19-21 in Indianapolis? I would like to check out the suspension on the G8 and possibly go for ride.

I think this forum needs an "IRS/Camaro Suspension Guide".

I know quite well how the 4th Gen front and rear suspensions work, and which parts go where, but with such a change in suspension design, I am confused as to which bushings go where and how they will affect performance/street ride...

I know there might be other 'IRS Explanation' guides out there, but we need one specific to the Camaro, maybe with a drawing/rendering of where each bushing and suspension part is located...

I am glad to see that Pedders helped to design the Camaro's suspension; in fact, I even remember Pedders posting some info about the Zeta chassis a VERY long time ago, hinting at their involvement.

EDIT: For example, I can't tell if the picture with the two suspension arms and the Pedders stickers is for the front or rear...

One more thing: are the pedders suspension arms built with the strength of the OE Manufacturer (GM). I know on the 4th Gens, that aftermarket K-Members (front subframes) and A-arms were weaker than stock and had a tendency to fail under street driving stress and mileage...

The arms are front radius rod arms. GM did the arms. Pedders did the bushes. The OE architecture known as ZETA and ZETA II is simply outstanding. Excuse me for being a cheerleader, but it really is good. There are constraints of price point and corporate suits that get in the way of taking the ZETA family to virtual perfection. That is where a company like Pedders fills the void. GM did all the heavy lifting and hard work. Pedders is just helped polish an already existing diamond. Pedders just a small part of the Camaro TEAM, a very small, very proud member of the TEAM.

Good suggestion on the diagram. We have a great one for the GTO.

We need a similar one for the Camaro.

That term confuses me because I don't have much knowledge yet about the ZETA II platform.

On the 4th Gen's there were upper and lower A-arms, and that was about it...

The ZETA II Camaro may well be the most structurally sound vehicle in the GM line-up exceeding the strength of the 322 / CTS. Keep in mind the CTS is as strong or stronger than the alleged best of the best coming out of Europe.

The Camaro as delivered from the Dealer will be the best of the Modern Muscle on the road and with modification to the engine and suspension capable of running with anything short of the exotics. There is a reason Chevy built the ZR1. It is called the Camaro.

bump.....

From what I hear about SEMA 2009, there will be some monster Camaro that will test the limits of everything on the vehicle. I can't wait to work on some of these projects.

Not long as we already have product here in the USA.

We want to fit our Xa kit to a production Camaro to be absolutely certain there have been no changes that impact the fit and performance of our bits. When we do release the kit, you can expect to get results as impressive as this.
