More!!! Please!!

These help quite a bit.

Now I can start picking out parts for my 5th Gen.

To me, suspension first, then power (unless I get a Z28)...

EDIT: Is there a front upper A-arm on the Zeta, and where does the tie-rod(for steering) attach?

no upper control arms,
Tie rods connect to the knuckle in front of the strut

So, was the purpose of the upper control arm to bear the load from the wheels, or was it just to align the shock in correct direction?

Also, how does Zeta II get away with no upper control arm, there has to be a different supporting/alignment piece...

The upper strut mount is the load carrying part of the suspension, the radius rod and lower control arm are not load carrying. (Load Carrying=holds the car up) The strut is a structural part on these.

Good question, throw me the keys and we'll find out

550 at the crank or the wheels?
Auto or stick?

550 at the wheels with an Auto will probably be ok,

550 at the crank with a stick, not so much.

With that said, until we have a chance to beat on them we won't have a definitive answer

Pete's G8 is approaching those numbers with a stock driveline, and no problems.

Yeah im planning on 550 at the crank through a stick. You see i really dont want to replace the badass rear suspension unless i could get basically the same axle just more beefed up.

It depends on the suspension. Zeta doesn't use an upper a arm either. The difference in a strut and shock is the strut is a load carring component while a shock is just a dampner. Your suspension will work without shocks (though you'll bounce like crazy). But without struts the suspension would collapse.

If you look closely at the 2nd pic you can see the radius rod in the lower front(I'm not sure what the official name of the other rod is). it controls movment laterially. All of the vertical force on the suspension is carried through the strut. The remaining forces in the front/rear and side/side directions are carried on the radius rod and the other support torwards the rear.

As for the Hp numbers there are plenty of GTO's in that range doing fine on stock parts. You can distroy stock drivetrain parts with little more than stock power if you shock load the drivetrain.

WOW! To me, the shock and spring combo have never looked like they could really support a lot of load, like in Autocross and road racing application. They looked more at home on a Civic or Corolla, with the front of the car being a lot lighter.

So, between the spring perch on the shock and the 'hub mount' (where the shock attaches to the lower suspension) will take all the load of the engine and any extra forces placed on it during cornering... I hope those shocks are reinforced on the inside and not typical 1/16th" steel tubing!

Also, does the load bearing nature of the shock make them more expensive to produce, possibly doubling the cost of, say, a set of Koni shocks (the holy grail of affordable performance for 4th gens)?

The 3rd Gens all ran a modified McPherson strut, where the strut was the load carrying member in the front suspension, the 5th gen will be similar and will not be a weak point.

While i was a Koni guy with my 3rd gen, it will be far from the only option for the Zeta (II) cars like the G8 and Camaro, and the cost will be a bit higher for the new car simply due to the technology being a bit more advanced than the old style dampers.

The thing I like about my current 4th Gen Konis (3rd gens in the rear) are the adjustability and fact that they are built better than most other shocks. Bilsteins were almost as much money after they were revalved to the correct settings and with the Koni's you can change the rebound as often as you want.

Where are the Pedders struts going to be made, and what are your quality control processes like?

They are made in Australia, and the quality control is very tight.

Just to give you an idea of how the quality control is, Every single spring that we sell is completely tested, from ride height, to rate, everything is checked, and if the spring fails to meet our very high standards the spring it then it is thrown in the trash and the metal in that spring is sent to the scrapper not melted and reused.

Pete can tell you more about the quality control that Pedders uses,

I'm not 100% sure on that, I can tell you that we tested a Stock GTO at .83, and then tested my GTO (Complete Pedders Track 2, and Bridgestone Tires) at .96.

the most important things i got out of him were

1. the camaro with the fe3 suspension will pull .97g in lateral acceleration on a skid pad. in comparison a porsche 911 turbo does .96....yes thats right a chevy is better from the factory. getting over 1g is a matter of changing to grippier tires. just think what it will do with the pedders bushing set. Al also said he he thought the pedders hard bushings would give it alot more.


2. for all the people wanting to run power adders on the engine and were wondering about the rear end IRS. dont worry. All said they have run 650 WHEEL HORSEPOWER thru it and it was still pristine he figured the stock rear end could handle much more. how much more i guess would be up to you to find out....

i also sat at the same table with John cox the accessories manager for the camaro. He was super great to bounce questions off of.

1. the blade spoiler is alot better then the normal rsv6 and ss spoiler and has been wind tunnel tested.

2. the ground effects kit has little effect on the aerodynamic properties.

3. there will be a hurst short throw shifter option for the car that makes the throws even better then the standard car and will be available with a pistol grip, t-handle or standard hurst ball shift knob.




really when at the moment i am so excited i cannot process all the joy i feel about the car and its capabilities. its just so much more then we could have asked for in this price bracket. its just simply amazing


i will post my pics later but now i have to go to bed since i have to be up in 5 hours to catch my plane.

good night all, Today was an AMAZING DAY for all camaro lovers. this car is so much more then i even dreamed of and we should all be rejoicing.

Oh, wow to the above post! .97!!!! I doubt the 650RWHP statement, but you never know.

Will that Hurst be like the last factory Hurst-a lot more throw than aftermarket shifters?

This tubing is all that is needed. It's kind of like standing on the end of a pipe. It will support a lot of load as a column but it will bend easily if loaded from the side. Thats where the other rods come into play.

As for Pedders stuff. I had it on my GTO. There were a couple of minor problems with the design of it. It basically caused some noise. Last I heard pedders was looking into it and taking the very minor issues very very seriously. And thats a good thing.
