Au Irs?

T_Terror · 16-05-2005, 09:22 PM

Hi, just a bit unsure of some facts.

Which AUs had the live-axle setup and which ones had the IRS?

Was it later series that got the IRS or specific models?

Thanks

All AU's from series 1 had IRS on the XR6 VCT (not utes), XR8 (not utes), Monty Ghia, Fairlanes and LTD's.
Also, all the T Series had them.

It was also an option for all other models although it was rarely taken up.

AU2's & 3's had IRS with the sedan XR6 VCT models. Not sure on the AU1 though? Casper?

Casper · 16-05-2005, 09:31 PM

Well, mines an AU1 1998 (early EARLY model) and its got IRS.

It was from the day they first made the AU.

16-05-2005, 09:54 PM

Yep... AU1s had IRS.

jonbays · 17-05-2005, 08:00 AM

ALL AUI/AUII/AUIII Fairmont Ghia, XR6VCT, XR8's, Fairlanes and LTD's had IRS standard.

IRS was also an option on the Forte, Futura and Fairmont Sedans.

No option for IRS on utes and wagons.

So the only sedan you couldn't get the IRS on was the XR6 HP, due to the XR6 VCT model.

as far as I know, that was the deal.

That said, hardly any model that wasnt fitted with IRS std took up the option.

ive seen afew fairmonts (non-ghia's ) floating around the auctions in the last few months with IRS....but it was very rare non popular option for some reason- strange because its a damn fine piece of work....

What benefits would IRS have over standard?
My mates R33 has it but axle tramps really bad when driving spiritly around in circles

Also the premium models had a non Adj camber bolt for the upper control arm.
Which if you lower the car you have to get the camber kits that was fitted to the XR's or face cutting the rear tyres life short.Set up correct with lowered springs and performance shockers plus new performance tyers the IRS really grabs around cornners.

Hehe yeh thats why im asking.

IRS = more grip and control

Would stiff suspension negate any real benefit htough?

Casper · 17-05-2005, 10:18 PM

The XR6 IRS is FAR FAR FAR too stiff. I'm getting mine lowered and dramatically softened in a few months. I dont get axle tramp but by god the ride can be harsh over a choppy surface.
It never bump steers at all (not once in 2 years) and really does grip extreamly well but its far too firm, a bit of softening and it will be so much better.

T_Terror · 17-05-2005, 10:35 PM

You serious?

I used to drive the old AU XR6 a fair bit and id say it was too soft! hehe

Each driver has differnet preferences.

Mines anything but soft. Its massively oversprung at the moment, anyone who's been in the car can tell you it should have come with kidney belts as standard.

b2tf · 17-05-2005, 10:48 PM

Our AUII Fairmont has it, I was actually under the impression it was standard on Fairmont (non Ghia) too as I have never seen one without it?

I've seen a AU futura with IRS in a car yard I had to look a couple of times to make sure it did not have the XR front replaced. So I gather they must of been a option for the non XR's and premium models.

not sure but I know mines way to firm. Cant wait for it to be sorted out now, I'm starting to dislike anything thats not freeway smooth :(

Perana · 19-05-2005, 04:49 PM

Our AU2 HP is very firm... needs to be much softer ( and lower! ) at the back...

cArSiK · 19-05-2005, 04:52 PM

a set of kings should help that....i regret not putting super lows in when i changed my shocks......plain stupid!

Casper · 19-05-2005, 04:53 PM

Hmmm, I have a set of IRS superlows sitting in the shed right now :P

Perana · 19-05-2005, 04:54 PM

I know you do shane... fit them already ! :P

Soon, all in good time.
No point just slapping them in without doing all the shocks and setup right.

Perana · 19-05-2005, 04:57 PM

That is true... some decent shocks and setup right should make it lauch nicely !

Casper · 19-05-2005, 05:01 PM

not to mention a 3000rpm stall converter that is going to be done at the same time

cArSiK · 19-05-2005, 05:01 PM

hmmm superlows........what shocks will they live with?

Casper · 19-05-2005, 05:05 PM

Still figuring that out. Probably just Monroe GT's for a start till I can work out whats the best for my needs. So many choices unfortunatly.

cArSiK · 19-05-2005, 05:07 PM

well i can say im very happy with GT's , but yes there are so many options out there its just not funny. At less than $100 each strut you cant go wrong..
