Our Pedders eXtreme Xa Coil Overs have been race proven in a multitude of platforms. In Fact, they just won a major award for one of the best aftermarket accessaries in Au. We have several hundred already in the states on the GTO, G8, and Subaru.

So what are the Pedders eXtreme Xa coil overs and how are they different from the majority of the coil overs out there?
Here is an explanation of the Pedders eXtreme XA Coil over:
1. Mono Tube design
2. 30 Way detented adjustable damping
3. Separate coil trapping adjustment.
4. Height adjustment done by not playing with coil spring rates and height

So lets review them with more detail.
1. 30 way detented damper adjustability. Some struts out there there have a dial that you put a certain position for damping levels. Without having them detented, you are only guessing at the rates. When you have 30 specific locations or adjustments you can ALWAYS repeat any settings as long as you can count. When you are in the 15 and above clicks, you should be able to tell the difference between each click. Here are some general areas for detent adjustments:
a. 2-5 clicks will give you OE damper performance
b. 12-15 clicks will give you a general street/canyon run performance level settings
c. 21-25 clicks are all out race race levels and too firm for normal street.
d. 30 clicks you are popping or making hemorrhoids!
Adjusting the struts is as simple as turning a dial and counting

2. You will have some serious height adjustability, and to be honest, more height adjustability than the Camaro can handle to maintain proper geometry. Now normal adjustable struts you lower or raist the lower spring seat to raise/lower the vehicle. But this increases spring biases. So with our Pedders Xa coil overs, we preset the coil preloads and then leave them alone. Then to adjust height, you will screw in the strut in/out of the of the lower knuckle bracket. This allows you to change heights and still keep normal spring travel. This is a big deal!! It allows you to have more of an accurate corner weight balance. Height adjustments will be from the -.5inches to a very low 1.5 inches. We will have a selection of coil rates for you and am not sure yet what the sport coils will be for the Camaro. But the G8 is at 7 to 8 kg/mm front and 10kg/mm rear. conversion factors have errors in them but to give you an approximate rating you might understand, 1kg/mm will equal 55.88 lb/in

Now what does all this mean? Instead of going into a lot of explanation, lets talk about results.

We just recently did a major track verification day in New Jersey, using professional drivers. We tested 3 TrackII Xa coil over systems with 3 different types of tires on a skid pad test. They pulled a 1.01g with split configured tires, 1.03g's with Michelin PS2's, and a 1.05g with Forgeline 19x9.5 ZX3 Wheels Bridgestone Potenza REO50A Pole Position 275/35/19 XL W. As a reference, a stock G8 GT with 19s turned a .93g. The magazines rated the Camaro with 20 inch tires at .93g with FE2 and .90g for FE3. Yes, the V6 will out-handle the SS,. Now a Ferrari Enzo is at 1.01g at $250,000 plus.

Even a HHR with Xas turned a .97g!

So how did it actually perform on the Track? In a 10 lap event. Pete's G8 was almost 30 seconds faster than a Z06 and a Porsche GT, both with Track Tires. Now Pete's G8 is running a Pro Charger, and the suspension was was set up for a road coarse.

So where are we at with the Camaro? This week the Camaro Xa Beta struts were air shipped to us. They are currently going thru customs. We already have a special Camaro set up to install. More on this Camaro later.

So we are in great shape. Camaros are in transit to the dealerships right now. We have all the bushings already in stock, and will have sway bars and strut tower brace very soon.

More info on the Xas can be seen on our website at:
http://www.peddersusa.com/products/6

Now what is the best way to get Xa"s. Buy them with a system. We will have multiple systems very soon:
Street Xa
eXtreme Xa package
Street Xa Plus package which will include sway bars.

Buying a system will give you some fantastic discounts over buying parts individually.

The Track II info above is preliminary. The parts are correct, but the pricing discounts have yet to be finalized. Our merlin store lists the TrackII at $2599.99, but parts are iincomplete.

So here are some preliminary systems for you to look at. We will probably have a Street Xa Plus system that will include our sway bar kit. This has not been done yet. the pricing levels should be determined and accurate by the end of the month.

Now to give you some idea of the outcome of the eXtreme Track System, lets look at the 3 G8s with this system on it that we just checked in New Jersey. Now a stock G8 GT with 19 inch OE performance tires, turned a .93g on a skid pad. The 3 G8s with this system turned a 1.01g, 1.03g, and a 1.05g. The variations in the 3 has to do mostly with tire and wheel configurations, and alignment. As a reference, a Ferrari Enzo has a skid pad rating of 1.01g.

Now that there are a bunch of Camaros in transit to the dealers, we will have specific data hopefully on Camaro in 45-60 days.

Awesome info! Just made a blog entry about it...

Pedders eXtreme Xa Coil Overs Will Find a Home on My 2010 Camaro

 

Now I know this is a G8 and slightly different. But the before/after shots will be fairly comparatve to the Camaro

I just finished a Xa Street System on a G8 at Abel Chevrolet Pontiac Buick in Suisun, Ca. Its a new G8, the same color as Petes, with 19s. The owner wanted a slight old school rake and the fronts to have the fenders nearly equal to the tires. This is exactly what we did.

Originally the heights were at 652-655 front, and 650-653 rears. After installing the Xas, we set the fronts to 600mm and the rears to 610mm. The front dampers at 16clicks and the rears at 12 clicks. This is a moderately aggressive setup.

Here are the before and after pictures:






Now we have done a very serious amount of testing, and corner balancing of Pete's G8



Now Pete's G8 s corner balanced. Production vehicles with limited option lists are very consistent in weight distribution. Using the locking collar measurements as presets for your Xa coilover installation will get you close to a corner weighted vehicle. While the car would not be coner weighted, you starting point for corner weighting will be pretty darn close.

RF 33mm / FR 610mm
LF 29.7mm / FL 610mm
RR 30.5mm / RR 595
LR 38mm / LR 593

Now Pete and have have different goals in mind. Pete;s G8 is all about performance and it does exactly what what he wants. Me personally I do no like the back end look. but to get the G8 balanced correctly, it needs to be 15mm lower in the rear. ( GTOs and LXs are the same). But as long as the customer is not racing, I like the old school slight rake, and the stance of the G8 at 600 front and 610 rear.

Your thoughts.

Camaro Xa Kit #1 is in the building!!!

We have to validate the fitment from pre-production to production Camaro. As soon as we get our hands on a production version and verify there have been no changes we will turn on the production in volume. Anyone have a PRODUCTION 2010 Camaro in the Michigan area they are willing to let me play with for a day?

 

Oooohh! Oooohhh! Pick me! Pick me!!

Awesome, someone should have theirs soon!

 

Looks Great! Glad you finally got it. Can't wait to hear how production fitment turns out.

 

We really are waiting on the first available 2010 production Camaro. Anyone with an early release vehicle who wants Xa coilovers should call me as soon as their delivery date is confirmed.
