It is all about balance. The reason we drop the rear is to be more composed when braking. Weight shift to the nose in most 'race' cars in highly desirable. In a 5th Gen it over loads the front tires and unsettles the car. Dropping the rear translates to less dive on braking.

In the front you have a linear suspension movement. The wheel goes up an 1" in the wheel well and the spring compresses an inch. Jounce travel is the distance from the top of the strut tube to the bottom of the bumpstop. For this discussion we'll say it is 60mm. If you lower the front 1" 25mm you have only 35mm of jounce travel. Going hard on the bumpstop unsettles the car in turns. In the rear there is a motion ratio. For this discussion we'll say the rear wheel moves up 1" the spring compresses 1/2". If we lower the rear a bit we don't lose as much jounce travel.

The 285s squared are mission critical to the handling of the 1LE. If you go to 305s in the rear and stay with 285s up front you are back to the understeer found in a SS or damn close. The Z/28 runs 305s squared. My Pedders USA Camaro ran 305s squared way back in 2009. If you add 305s to the rear, finish the job with 305s up front

This forum does not allow me t post pricing or links in the thread. I'll send you the links in a PM.

PS: The forum does allow C5 members to post links.

Well let's say I go 305 rear and run a Permagrin kit doesn't that compensate to a certain degree for what I lose with the loss of the square setup?

As far as the springs go I want to close up the wheel gap to a certain degree. I understand your point about the travel and also the loading of the brakes. So I'm not sure what to do then. I know Supercars is the real answer.

The idea of 305's all around is appealing but that involves new wheels. Or is there a way to pull it off with my stock ZL1/1LE wheels?

I think what will have to happen is either late December or early January. I plan to have Suspension and Aero done by mid year.

We measure fro the lower rim lip, up through the wheel center to the edge of the fender in mm. Why mm? 580 on one side and 583 on the other is a difference of 3mm. Very simple compared to 22.834645669291" and 22.95275590551153"

Do you mean 680mm for a 20" wheel? 580mm is awfully low...

OE is about 700mm in the rear so yes it should rear 680mm. GREAT GET!!!!

The price difference is not an issue per say it just means i will buy less at a time with one vs the other. Then there is the fact that i wanted to do and "SSXish" replica and that car has everything pfdat makes.

Pedders. Hands down.

[JusticePete]

The SSX is a show car that never ran a hot lap. Not a single one. Then there are the Pedders cars that have been the fastest late model muscle cars (Camaro, Challenger, Charger, Mustang) at every event I have been involved with going back to our first 2009 OPTIMA Ultimate Street Car Challenge.

I take these events and results personally. Starting back in 2009 we documented the build of our first Camaro. We published the test results along with our setup details here on C5. It is a how to book for the 5th Gen. It contained everything we did. How hard can it be to beat a team or car in a race when they have published a book for you to follow?

When we beat the other brands 5th Gens at the 2009 OPTIMA following SEMA they were shocked that we had 560 RWHP.They were shocked we had a complete suspension on the car. They didn't like my friend Paul Tracy driving my car. How could anyone be shocked that we showed up with the car that was built on the C5 forum?



We ran in exhibition class and felt great about our road course time until a killer Cobra race car nailed it. Since then I have invited everyone and anyone to come out and beat us. Come and take away our spot as the fastest 5th Gen. We still share our setup information on C5. We are still the fastest. One of these days we'll lose that spot and I'll tip my hat to the victor. Then I'll figure out what we have to do to beat them and reclaim our spot.

Imagine you are an engineer for TEAM Camaro. You are part of the great crew that built the Z/28. You did your homework. You did the testing. You end up with 305/30/19s on your favorite project... just like the 305/30/19s I ran back in 2009. My 305 fitment that some other suspension company made jokes about in 2009 when we posted this thread and said we can run with a Z06 Vette.

Have a great weekend Mike!

We beat ZR1s, Porsches, GT-Rs, $250,000 Pro-Touring cars...

Kind regards,

Looks like the Z/28 went a different direction than the SSX.

I do tell anyone that will listen how good we feel our setup is for the 5th Gen Camaro. I do it in great detail. I tell them we are the fastest. I have never pointed and laughed at another company here on C5 and never will.

His car is up for sale and some fortunate person is going to be thrilled with it. He listed it as the 3rd fastest Camaro in the country and it is He could have been the 2nd or 1st fastest with a bit of RED

Good night all.

Damn... just reread this thread. Tons of great info in it. Pete needs to come back 100%. His info/knowledge is too much.

Hope it's all working out for you man...

I am looking for a 1LE owner that would like 530 RWHP from an N/A motor. Drop me a PMif you are interested in sharing costs on a project like this.

So you want to build a cammed 1LE now? Interesting...
