Yeah 1-1.5 would be about ideal. It's amazing how many different shades of blue IBM has depending on the light. I don't think I've seen it look the same way twice in all the pictures I've seen posted of it so far. Can't wait for mine to arrive!

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

I am/have been working on a preset relationship that appears to be working pretty well.

Now to adjust, you loosen the lower lock nut that locks the strut to the lower mount, then use the included spanner wrenches to adjust the strut in/out of the lower mount

It is not complicated.

Thanks, Mike...sounds easy enough.

When you get yours decide the height you would like to be, and the measurements of all 4 corners. email me and I will give you pre settings. Follow exactly the installation instructions on setting spring heights, and you will be very close on all 4 corners.

thanks

Thats what I'm talking about!! Thats the ride height I'm looking to achieve. I want to put a set of 22's in the rear and 20's in the front. That looks great!!

Hey man,

you asked for it, and now you got it!. Ride quality was fantastic. But she does not like driveways. Speed bumps, however, seemed OK. We did the angle drive for the driveway that seemed to work.

Mike, Jordon,

Thanks for one of the best threads I’ve seen in a long time.
Having previously had 2 bodies and 2 vettes, so this thread was particularly appealing
I had my 71 Formula Fbird set up for canyon running (back side of Palos Verdes Ca). Herb Adams was my hero of the era, and he focused a lot on sway bars. No doubt it had a lot of understeer even with a square setup all around.

I’ve had two vettes since, and CCW made me a great set of wheels and I ran the car at summit point.
They know how to fit that rubber in the fenderwheels, but I’m looking for a different wheel style for my Camaro.
That said, with 315s on the vette, it then understeared, but I could mash it coming out of the turns, (but not as much fun as when it was balanced though...lots safer for my amature skills however).

One observation I have made from reading both of your exchanges is this. If you fit the largest possible tire in the front, it will be hard to go so large in the rear that the car would need excessive tuning in the suspension to help balance it out.
So, my thoughts are this, try to fit 285s up front if at all possible. With that, then the customers preference from 285/305/315 in the rear should all be tunable. THOUGHTS???

Going for looks now (hey, not single anymore, so weekends at the track will be few and far between )

I really liked how the concept was set up. I think it had 22 rear, and 21 front

Staying with that idea, but keeping it in line as a daily driver,
I’m thinking for looks, lower 1/2 inch in the rear, and 1 front (maybe 1 and 1 ½) Is there a way to do this without coilovers?)
21 x 11 rear w/ 315 series (or 10.5?)
20 x 10 front w/285 series (or 9.5?)
Who makes wheels in these sizes??????????
Who has tires on the smaller side of this size range. (like whose are more like 280mm and 310mm)

How close to ideal would this come in terms of setting up for handling? (can I have my cake and eat it too?)
Have either of you done any testing with different diameter wheels?
Should I look at sway bars or adjustable coil overs to fine tune the setup?
Also, with coilovers, how much time would it take to adjust for the drag strip, and back to the street again? I don’t have too much trouble with traction, but in the near future, I soon hope to have.

Thanks again for some great and thoughtful reading!

Your height goals can be easily done with our Pedders coil overs. You could get close to your goals with this coil kit:

Camaro Performance Drop Spring Kit 2
7/8/09 Merlin Store P/N is CAMAROKIT2
This kit is for the enthusiast that is looking for that aggressive look with with a more performance oriented handling experience. The fronts are a 20mm drop and the rears are a 40mm drop. This look is a European look, and will seriously reduce the significant amount of understeer the new Camaro offers.

In terms of sway bars, if given the option I would always recommend updated bars.

I would always as well, recommend the least split configuration as possible. With that said, the larger you can get the tire in the front the better. I would prefer you doing a 285 or 295 in the front with a 305 in the rear. You will also be better off in terms of handling to have the back end 15mm lower than the front.

295 in front!
I've read about and have seen 275

Has the 295 been done?
I'm thinking about 295 all around now....

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!

No problem! Just trying to provide some good information!

Our testing from a performance stand point is always done on a closed course; we don't support "canyon" or "street" testing. We have a garage at Miller Motorsports Park and we conduct our testing there. We started with sway bars because you must first provide balance. We engineer suspension components not tires.

The first product we developed and tested was sway bars; they provide ultimate balance and allow the customer to fine tune the handling to there liking without effecting ride quality. From there we developed our Coil Overs and drop springs. We've also developed Poly Control Arm Bushings, Solid Subframe Bushings, Engine Mounts, Diff Bushings, and a strut tower brace. We will have track data on those shortly. With our systems you can piece together a system or purchase it complete while retaining factory tires/stagger with huge performance gains!

I appreciate the kind comments about Pfadt! I know you have great customer service and take care of your dealers! We take the same approach and we look forward to supporting the Camaro community along side Pedders and the other manufactures.

Thanks Mike and have a great day!

Kind regards,

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......

I put 275-40-20 (stock rear size) Vredestein tires on front and 315-35-20 Vredesteins on the rear of my 2010 SS/RS on the stock 20" wheels. They look incredible, appear to have plenty of clearance inside and out, and have never rubbed front or rear under any condition. The tires stick out about 1/2" past the rim, which looks just right to me. (just enough so that any curb will touch the tire instead of the wheel)
