Disagreement please answer
Dear Friends,
a fellow co-worker and I are in disagreement about C4's have irs, he states it does not, as I do it does have IRS. He states due to the fact that it is monospring it is not a true IRS, due to his opinion that "true" irs has coils.
Someone please give their input.
Thanks,
Bill

Your co-worker is an idiot 
IRS refers to the fact that each wheel on the rear end can move independently without affecting the other. The vette, even with a monospring does just that. Now that is not to say it is the most efficient way to accomplish this, but it is IRS.

If it's not IRS, then General Motors/Chevrolet, all the various Corvette books, and all the car mags (and I do mean all) have been wrong since 1963.

I seem to remember the old Triumph TR4's had IRS originally without a monospring or rear sway bar and had some problems. Many guys installed the sway bar to (probably on other types of cars too) to improve handleing and traction. I've always looked at the Corvette rearend as pretty efficient (although a pain to work on some times). Just tell your friends "Duh?!". It's an IRS.

Put some money down, like $100 and log in here and show him this thread. 
If he says, "Oh!" Tell him, "DUH!!!!"
Then demand your $100.
If he doesn't pay up, take a pic of him, PS a pic of an IRS beside him and put OWN3D!!!
Then problem is solved.
Good luck.

What kind of spring the rear wheels have does not determine if the suspension is independant or not. IRS is determined by what happens to the opposite wheel when you lift or drop one. If independant ,nothing happens to the opposite wheel and ALL Corvettes have had IRS since the 1963 model year.

Just jack up the car on one side and when the tire doesn't tip in have him take a look. Maybe then he will come to his senses. It sounds like some other idiot probably put that nonsense into his head. The vette could have in fact had coil overs if GM wanted them on it.
Correct me on all the areas I am wrong please. But I think the Leaf spring is Cabon Fiber, lighter and surves a dual purpose. It is a spring and a sway bar. The car should be more stable with it then without. Also faster with it thean without. Its only real problem is it is non adjustable, it must be replaced with coil overs for fine tuning at the track, or you will need a multitude of replacement springs to go in its place.
I think are some adjustable leafs on the market though. I saw one on a C3 on TV the other day.
If the coil overs were that necessary GM would have them on the car now, at least the Z06 anyway. Does it have them? Does the C6R? or C5R? I bet the race cars do, but I dont know.

What does your buddy think IRS means, though? The car has a mono-differential too, and the suspension is mounted to a mono-body. Does that make it not a "true" IRS?
