I have been doing alot of research lately on going a solid rear end or a heavy duty I.R.S for my car and I ran across this set up.

Details:

¡ÜLight weight aluminum 9" center housing.

¡ÜStub axles available in 31 or 35 spline.

¡ÜIncorporates a large diameter upper and lower control arm.

¡ÜSimple on the fly camber adjustability

¡Ü58 ¨ö¡± Track width

¡ÜC6 Corvette spindles and hubs.

¡ÜAllows up to 14¡± disc brakes on the rear of the car.

¡ÜRear mounted splined sway bar.

¡ÜDesigned to allow up to a 12¡± wide rear tire.

¡ÜVented CV boots with high temp grease

¡ÜBuilt to handle up to 1400 HP



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.

We currently have the IRS in both 64-67 and 68-72 Chevelle (and GTO) chassis as well as 1st and 2nd gen Camaro Chassis, and Challenger/Cuda Chassis. Mustang chassis are next on our drawing board to incorporate the IRS into.

 

More furniture.

 

the whole point of going 12 bolt/9" is to get rid of the half shafts, spindles, and ujoints that inevitably will break...

 

This system uses a beefed up Cvc system like the new corvettes use only it's allot bigger. there are no ujoints,half shafts or outer axles to break.

 

Tim. How much for the set up?

 

To the naysayers that think solid axle is the only way:

Think dodge viper irs, uses cv joint axles vs. Halfshafts / u joints.

Let's get this thing fixed. If I wanted solid axle I would have gotten a camaro or gm a. Body.

Corvette and solid axle just don't seem to go together

 

But when ya put high horsepower to the IRS that initial snap will break stuff sooner than later Pipe

 

Ok. So it's a CVC system. that still means there are 2 flex points when there should be 0 and thus at least 2 weak points...For those only making a little more power than a properly setup 44 can handle this should be fine. for a serious racer i don't believe this is a realistic option.

 

I have been wondering if something like this would actually work.

 

looks really nice.. and like it would cost an arm and a leg.

This is brand new they don't have it priced yet but I'm sure it will be a arm and a leg not including grafting it to the car. But it looks pretty stout. I'm not looking for a drag race system I just want it to work autocrossing without breaking and drag it a couple times a year. The spacing from hub to hub is 58-1/2" I'm not sure what our C4 cars are but I'm sure there is a wheel out there that would work.

It's just the picture I posted up. Can you see that?

 

Looks impressive.

It would be alot of money to fork out up front.

Unproven till someone uses it in their C4 and races it at the track.

 

You know what that set looks like, the newer Ford sport trac trucks. The have irs & use an 8.8" pumkin.

 

So do The Ford Mustang Cobra's from 2002 till present... Ask one of those guys how well that stuff holds up when it's actually raced...

Will

 

Very bad.

Cobra independent rears blow apart in the 11's.

Not the 8.8' center sections but the halfshafts.

Our C4's are light.

Otherwise the independent rears in our cars would fail much earlier on with less torque if they weighed 3,500lbs to 4,000lbs like a Mustang in stock form.

 

A couple places are putting out 9" IRS kits for certain cars. It would be awesome to see one for the C4 but I am guessing the market is too small for them to justify it...

This is kinda like like the "Trying to get 500hp from a TPI intake" syndrome.


I do hope theres a solution from those seeking it but shoot if it was out someone would have done it long ago. Maybe there will be a solution who knows. You bet it will cost

 

The Cobra's problems were the half shafts and the way it was mounted.
