The Corvette is IRS as well, did you think is was not?

Your lambasting IRS Setups for Drag racing led me to believe the Corvette had a different set up- somehow leaf springs and IRS:confused:

See my underline of Slick's previous post :)
[QUOTE=Slicks]I dont see exactly what your getting at, you do know that the Corvette has a [u]transversely mounted[/u] leaf spring with IRS right?[/QUOTE]
(Pre-VE Commodore IRS is basic old-style 3 link [i]a-la[/i] BMW 2002 or Datsun 1600/510, while our local non-IRS cars are one [u]set[/u] of multiple leaf spring[u]s[/u] per side & longditudinally mounted like Roman Chariot. By contrast Corvette IRS system uses a [u]single[/u] leaf, positioned laterally. I'm guessing those 'C' bars on 1-Ton TT are probably what we call tramp bars aka control arm (OE fit on Falcon XA GT M4 eg) to alleviate spring wind-up aka axle twist)

C'mon, are you serious? So youve been arguing about a car that you know nothing about??? The Corvette has had IRS (and wishbone suspension) since 1963! They are [B]transversly [/B]mounted leafs, that means one in the front, and one in the rear. They are also composite, so they are lighter than coils, and will last longer too(and act like anti-roll bars).

[QUOTE=Slicks]I dont see exactly what your getting at, you do know that the Corvette has a transversely mounted leaf spring with IRS right?[/QUOTE]I do actually
[QUOTE=Slicks]That Holden Ute has two leafs holding a solid axle right?[/QUOTE]Yes
[QUOTE=Slicks]Far from what the Corvette has.[/QUOTE]Leaf springs are leaf springs. They have the same compression and rebound charateristics.
[QUOTE=Slicks]Like I said, almost all IRS cars get axle hop, thats one reason why a solid rear end is superior for drag racing.[/QUOTE]I've yet to experience "axle hop" in an IRS car
[QUOTE=2ndclasscitizen] They have the same compression and rebound charateristics.[/quote]
Thats where your wrong, the way the vette is setup is completely different from a truck. To top things off shocks make a night and day difference. I rarly hear about corvette getting wheel hop.

I guess you dont drive any fast IRS cars. From cobras to corvettes you gotta be careful it can get ugly.

I assume,by Cobras you mean mustangs, which have never had an independent rear, at leat not to my knowledge. Nevermind, you mean Shelby Cobras, I see what you are saying now.

The 01, 03, and 04 Mustang Cobras all do. Im pretty sure the Cobra R has IRS as well.
[QUOTE=Slicks]Meant to say wheel hop.[/QUOTE]The difference being?
[QUOTE=Slicks]Go drive a porsche.[/QUOTE]I'd love to. Do you have one I can borrow? Actually, have [B]you[/B] driven a Porsche? Or you relying on what people on Vette forums are saying about Porsches?
[QUOTE=rev440]I guess you dont drive any fast IRS cars. From cobras to corvettes you gotta be careful it can get ugly.[/QUOTE]I'd consider an LS1 Calais pretty damn quick, so are STis, so are 200s.

Shelby Cobras = solid rear end (many are built off the fox body platform)
Mustang Cobra (01-04) = IRS

Just making sure you werent confusing it with anything else.

That was a few seconds with google...

GTOs (monaros), STis, and EVOs all suffer from wheel hop, Ive personally seen it at the track. What are 200s?

[/QUOTE]
Yes... but no. First, just like there are different types of coil springs there are different types of leaf springs. I have a coil spring in my ball point pen but it's not very similar to the ones on my cars.
The Vette has double A arm suspension front and rear. It just happens that the springs used with that suspension are leaves rather than coils.
Here's some good info (sorry, the author was excessively wordy and rambles at times)

That was a few seconds with google...[/QUOTE]And yet it's never been a problem in any of the reviews I've read for any of these cars. Have you maybe considered the fact that it's due to the fact that the Vette has double wishbones, whilst the 3 cars listed in those links don't?

Ferrari's have double A-arm as well. As do Miatas. If the car has wheel hop issues it's not because it "has double A-arm". If it has problems it might be related to the implementation as seen on the Vette but it's not just because it has double A-arms.
Typically wheel hop is caused because some part of the drive line winds up the releases. That can include the suspension arms. Axle wrap in a live axle car is one example. The Cadillac CTS-V has problems with this because the rear dif carrier is mounted rather softly to the chassis (soft mounts yield good NVH). The Corvette's dif is not likely to wind up as it's connected to the engine via a log tube. The tube and the fact that the car uses a rear mounted transmission (wider spacing between pick up points holding the "rear end") keep the transmission and final drive inline with the motor.
Having driven a 2005 Z51 Vette I can say it was easy to spin the tires and I didn't experience wheel hop even with the factory run flats.
