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:

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.
