315 size rear tire...

[Tony SS]

I agree with you on the look situation. The wider tires in the rear definitely adds to the muscle car image......

Where we have a difference of opinion is that you have to run a square set up to remove the understeer. We've done this by engineering a sway bar package specificly for the Camaro and it doesn't require a square set up. Sway bars are the ultimate tuning tool as far as balance goes. For our customers that want to retain the factory package but want to make the car more responsive in cornering we've developed a "Balance" rear sway bar; the customer simply bolts it on and the understeer is gone. We have Chevrolet Dealers putting these on Camaro's on the show room floor. This is much cheaper than having to buy new wheels and tires. The next option is our Sport Sway Bars. They offer increased roll stiffness and maintain the balance found in our Balance Bar Package. The benefit of this package is a much more responsive corner entry as well as adjustability and reduced body roll. We know everyone has different driving styles and adjustability is the key.

I've run Gingerman and it's a fun track; small but fun! With a balanced package designed to work with 275's and 305/315's the car is faster than a car with 275's all the way around with our package. The car will have more overall grip including better corner exit because of the larger rear contact patch. If you're going for ultimate efficiency you want to get the biggest tires possible on the car and design the suspension to work with them; that's what we've done. Our Specialty is suspension tuning; the Vette's are neutral to oversteer depending on the model and we've balanced them as well through engineering and adjustability although it isn't nearly as sever as the Camaro.

We obviously have fundamental suspension tuning differences and that's fine. The ultimate winner will be the Camaro owners as they will have options and choices.

Kind regards,

Thanks for responding. This is a great interchange of ideas. There are some big differences on how both of us have obtained neutral handling. And so everyone understands, on our test we are talking race track driving, which is seriously more challenging that just normal street performance. We obtained a very neutral feel without sway bar! Your test was with sway bars. That is a critical difference. We will have our bars and all bushings next week. This will radically change the hole setup.

One of the other things, and I think Jordan you will agree with me, is tire design. We tested in Texas multiple tires and had a significant variations in handling. We will have at least 2 more track sessions and Pedders now has their own SS Camaro to play with.

So everyone knows, it is OK to have a difference in philosophies and ideas. PFadt is a great company and has done great things with the Vettes and I respect them a lot. We are different in our approaches sometimes, but at this point, we are talking apples and oranges. Jordan obtained a track neutral feel with sway bars added, and we did it without sway bars. If we compare our setups, I would assume they will be quite different.

I do understand the desires to have split wheels and tires. With the Pedders Camaro, we will strive for setups that will go very seriously beyond OE. both of us have obtained this.

Thanks Jordan for the info and interchange. You are a gentileman!

Mike and Jordan,

Professionalism at its finest.

Thanks guys for giving our members all of your insight.

Very much appreciated.

[Scourage]

Great insight, at first I thought the thread was gonna spiral. But I pulled a lot of good info out of this eventually.

[Tony SS]

Thanks everyone. I originally set this up hoping to get some quick opinions.
I never thought the excellent input would be accomplished. I definitely have been able to make up my mind as far as looks and performance on what to do......

I appreciate the help guys......

Here is what a 2 inch drop looks like







They are fitted with Pedders Xa Coil overs

enjoy

Is that the basement setting? Will it go any lower? I think I liked the level Hennessey had theirs set at. I'm not saying that doesn't look friggin' bad@$$; just I don't think I can get away with that level around my area :(

[GTAHVIT]

Looks bad ass but I'm thinking about 1.5 would be better for DD...

This will allow you to keep the tires in the fender wells as well as keeping them from hitting the inner fender without mini-tubing it. If you were to do a mini tub you could go 295 up front and from 315 to 335 (335 I'd run our rear sway bar full stiff) in the rear. The largest tires we've tested with thus far are 275 front and 305 rear; they fit well. All of our suspension comparison #'s will be using the stock tires; the reason is we want you to know what our suspension does not what a good set of tires will do.

Please feel free to call us if you have any further questions.


Kind regards,

Jordan, sounds like you have the hot setup for the street, can you pm me the prices of your kits? Thanks!!

This drop is slightly over 2 inches on this specific Camaro, It may vary, however, because we have seen as much as 15mm variations in heights from one Camaro to another, plus this Camaro had a 8mm variation side to side in the front and a 6mm variation in the rear. She is level now!

It was set up seriously low like this because a lot of guys have been asking about it and I wanted to show that it could be done.

This Camaro is trackable with the settings I put it at in case someone takes it for a serious ride, they will have a very seriously satisfying experience.

Now for those that get a little too aggressive with the rear tires and find they do now fit well, our rear Xa coil overs will bring the back end up approximately 1/2 inch higher than OE.

Wow, that 2" drop looks wicked. Nice work Pedders!

I'm not sure if you've posted it yet, but how difficult is the height adjustment procedure on the Xa's?

[Doc]

I see one big advantage a square setup has, especially for a street car and that's the ability to rotate tires to extend tire life. Which is why I plan on getting a square aftermarket rim/tire setup. I also like the idea of the reduction in unsprung weight a square setup has over staggered with huge rear rims/tires.

Jordan your setups seem to be primarily aimed at staggered; are you planning on doing a square package?
