Corvette IRS in a 1st Gen??

A guy was telling me last night that one of the Corvette IRS complete assembly fits perfectly in to a 1st gen as an almost bolt in installation. Anyone know anything about this? He thought it was the C5 Vette

Re: Corvette IRS in a 1st Gen??

It is six inches wider so far from an easy bolt in. This guy is putting an entire C5 drivetrain in his 69 Camaro. Stretched rear quarters.

Your best bet for an IRS in a first gen is the Art Morrison setup. Comes with a first gen specific rear subframe. Rumor has it Speedtech will be introducing an IRS setup.

Re: Corvette IRS in a 1st Gen??

You can keep your uneven a-arm front suspension (aka IFS, since IRS stands for independent rear suspension), and still use the big brakes off a C5-C8 Corvette by using just the taller 'vette steering knuckles on your Camaro front clip. Because the Corvette uses a taller steering knuckle (the spindle is the stub axle that the wheel bearings ride upon), it "fixes" the steering geometry issues with the first gen Camaro. They are not a bolt in and have to be modified to fit your Camaro so they are an aftermarket item.

If you want a 'vette IRS then you are going to need to modify your Camaro because the transaxle bolts to a frame you don't have, and it is larger than the amount of room you have under your car.

Re: Corvette IRS in a 1st Gen??

I know the C4 IRS setup is as close to bolt-in for a 3rd gen as reasonably possible. Maybe he thought that one would fit the same into a 1st gen.


OP, you are aware that the C5+ IRS is a trans-axle assembly right? Great for weight distribution (I'll be going that route in a couple years) but far from "bolt-in".

I have no plans to go to an IRS, I was just asking because someone told me it worked, as expected, it was BS. My plan is the Ridetech 4 link & mini tubs

I didn't think the torque arm would allow room for the GV overdrive unit?
