Speedtech's new 3rd Gen Camaro suspension

[Formula364]

Good News!
I have 2" drop spindles - roadrace version from RaceCraft. They are no longer offered. Very happy to have them. Here are some pics.
They are paired with: Spohn tubular adj a-arms and strut mounts, alum hubs, 2 pc 13" rotors & FSL 6pot calipers inside stock wheels!, and swivel cup weight jacks (bolt thru frame rail).

These limit me to 8" wheel. I've always felt that 275 is perfect for street (ruts) - not that 300+ is bad. My thought was a 245 with better RC is equal/competitive to a 275 with worse RC and scrub radius.

Some more thinkin' to do.

I think this thread should be closed until it contains updates from Ron or Speedtech... my hopes keep jumping and the falling hard! (Just a joke)

Then again, the longer they take the more time I have to get the funds....

You may be right. we had planned on starting this year but jsut too many other things to contend with first.

Sorry to get you all excited.

That spindle does provide a decent start point. The biggest improvement that can be made I can see is moving/shortening the steering arm.

I would love to see X-Rays of those welds. After seeing the failure on the non-road race version on TGO (yea, I know, he didnt take heed to the warning on their website) I have suspicions. I feel like a fabricated spindle like that should be welded to the same strict standards that are used for AWS D1.1 3G and 4G tests or something similar to it.

I've had both the drag and roadrace versions in-hand. I'm confident with the beefier roadrace version! Yeah, the other guy road raced the drag version, and refused the upgrade when it was offered to him (post failure). I keep it bare to make it easier to inspect. RaceCraft put their best guy on these. I feel fortunate to have them.

I do wonder about aftermarket tie rod ends that might allow me to fit them inside an 18" barrel...hmmm....But I do prefer 17's and some sidewall at Road America. Technology improves and offers alternatives.

By altering the steering arm, you mess with the angle of the tie rods. Then you could alter the drag link to compensate, but.....then I'd get lost and over my head. Here is a crude drawing of the front steer.

This proposed set-up is a clean sheet design and looks promising! I'll look-on with envy, but it's beyond my finances.

I do tour with my car - want to drive it in all the lower 48 states. I have MS & LA (Nawlins trip), and a New England trip (everything North of Yankee stadium) left. Delaware was difficult to incorporate, but I did it. I don't think 315's will be practical for touring. Though this design will keep them flat.

For now, I try to keep scrub close to zero by 8" wheels, SAI mods, and use moderate camber. The drop spindles and lower PHB help the roll axis inclination, also. And, I continually look for ways to be able to go wider, but I drive my car alot - 240k and counting (all mine, original owner). I'm lucky to see one HPDE a year. These cars are fun to drive, and with low unsprung weight and an LS2, it has exceeded my expectations.

shorter/repositioned steering arm would mean more affordable rack and pinion options. that would be the reason for an option for the redesigned arm for me.

Sounds like you made your bird a hell of a GT car.

Someone over on FRRAX has the stock spindle blueprint:
