X2:thumbsup:

A second gen Camaro application would be pretty cool.

Wow. I've said it before and I'll say it again. I need to hit the lottery. Nice looking chassis. Great job.:thumbsup:

What are thoughts on exhaust/tail pipe routing? Dumps? Is there enough room under the center section?

Thanks Rich

Rich,
The crossmember has two recesses in it to allow for 3" exhaust to pass above the axle. There are holes there for an exhaust mount that we are going to offer as an option. We are going to be starting on the exhaust for chris's 66 chevelle in the project section. I'll get a few pics posted as we get there.

What is the track width on the rear? Looks awesome:thumbsup:

This is a really cool way to get IRS in side a muscle car.
Tim Bruning has done a similar set up before at SAR. SAR used more GM Facotry components. There hasn't been any true hard testing of the system. Show car type stuff.
Lets get some real world testing!!

Thanks, the track width is 58.75" which will end up at 59" with brakes. We had a lot of discussion about track widths and possibly going narrower to get a deeper lip on the rear wheels, but decided on maintaining the optimal geometry and performance rather than sacrifice that for looks of the rear wheel. We designed it to be considerably narrower than a stock C6 Vette IRS. Depending on the car, you should be in the 6" - 9" back space range on a 12" wheel.

We are working to have Chris's 66 out for the Motor State Event with the IRS and we will have a 2nd gen of our own shortly behind that.

SAR definitely does some top notch stuff. We looked at the stock C6 components and saw a lot of room for improvement. By building our own conrtol arms and cradle system we were to make several improvements over a stock C6 IRS.

We have increased camber gains in roll compared to stock C6. There is 1 degree of negative camber gain through 1" of compression. This makes sure your tires never gain positive camber (like a stock C6) during cornering, losing traction/grip.

We were able to closely match camber gains to that of our front suspension which will yield a much more balanced and predictable car

Upper and lower control arm mounting points are pitched to give your vehicle 55% anti-squat, NO OTHER IRS OFFERS THIS, (Anti-squat will make your tires plant harder to the ground to help with acceleration and traction out of corners and from a launch)

We were also able to stand up the coilovers drastically over what is possible on a stock C6 arm giving more desirable a motion ratio.

Our upper control arms are also easily adjustable so caster/camber can be adjusted with shims while at the track.
