IRS into older model VN-VP Commodores.

**Full Spectrum** · 18-10-2006, 12:14 AM

I know the IRS was on the stato's and Some VP executives and VP Calais.
But for a live rear VN-VP can a IRS system be fitted too a live rear car? Has it been done or can it be done curious?.

**immortality** · 18-10-2006, 06:39 AM

anything can be done if your willing to spend the $$$$ but it wouldn't bolt straight in if thats the answer your looking for, totally different in the way it's mounted to the car etc be cheaper to find an IRS model your looking for

**Full Spectrum** · 18-10-2006, 08:47 AM

I know a guy that runs a wreckers and i might get into a convo with him about it see if he can do it cheap

**1991_Vn2nV** · 18-10-2006, 10:17 AM

But whyyyyyyy

What is peoples obsession with the waste which is Holden IRS?

**Full Spectrum** · 18-10-2006, 05:14 PM

It should keep the rear more happy on bumps

And some extra weight over the diff would be nice too.

**HoZy** · 18-10-2006, 05:36 PM

You have a pretty much stock 6.. Why do you need the traction of IRS...

unless you have alot of money to throw around, I wouldnt bother putting IRS in, not worth it. my personal opinon anyway

**4PLAYN** · 18-10-2006, 07:30 PM

Would it be advisable to put IRS into a VN that has a slightly worked 8 in it .... might even be supercharged?

What benifits do IRS have over Live Axel?

Damn it Adam... lol

Benefit... Ride quality and traction on uneven surfaces.... Thats a general IRS benefit, but Holdens excuse for IRS is debatable

On flat surfaces nothing beats live axel. Have you ever seen a drag car with IRS??? No...

It reduces rim choice and puts a whole in your pocket as things suddenly become a lot more expensive to suit IRS.

Holden IRS is crap. Until the VE atleast.

**4PLAYN** · 18-10-2006, 07:50 PM

OK, VQ V8's have IRS .... are they the dodgey ones as holdens trial version or something.

Last time i checked the street wasn't a race track Dylan :P

Drag Cars dont go around corners, they drive and operate on CONTROLLED roads (dragstrip) which is flat, not many bumps and hasnt got the normal wear and tear as what Main North Road would have in Adelaide north.

Point. I dont have a drag car, nor would i want to have to drag people on the street. I have totaled one car already, i dont need another one gone aswell.

Cheers

**1991_Vn2nV** · 18-10-2006, 07:56 PM

The road IS a drag strip!!! You cant tell me otherwise!

IRS also hinders handling from what I've been told however I cant tell you the specifics. <-- If thats wrong dont shoot me down!

Even main north road is fine for live axel

Unless you count the intersection of regency and prospec roads where I always get wheel hop....

p.s. I do not participate in or condone any illegal behaviour on the road, including dragging.

**4PLAYN** · 18-10-2006, 08:00 PM

LOL

If the normal road is a drag strip ..... take a photo of your licence as you probably wont see it for 12 to 18 months.

Hinders handling?, I would have thought it would improve the rearward handling by more traction to the tarmac ....

Well thats what i think

Cheers

lol... I just get confused... drag strip has lights... road has lights... both are tarmac...

p.s. Dragging is bad. I do not participate in or condone any illegal behaviour on the road, including dragging.

**4PLAYN** · 18-10-2006, 08:08 PM

Yes .... you see two sets of lights on each ....

lights of the tree at the beggining of the 1/4 ..... the time sheet sign at the end of the 1/4

The traffic lights at the start and the cops car lights at the end ....

Your choice ..... Cops or proudness to say .... i did a legal 13.5 second pass ....

Cheers

What they dont know... Wont hurt em

They gotta see ya first...

I'm hoping one day too go for the L67 conversion or maybe just the Toyota supercharger, But no V8

. They feel a little light in the rear fast corners with bumps and i was thinking keep that rear down a little better

I'm going too talk too my friend at the wreckers about it maybe he can get me one cheap and do it. If he says it's a good few days job I'll say stuff it I'll work on what i have

.

I'm thinking it's them little bumps on corners that toss these cars around, Stick it too the light turn in a hurry because it's changing and hit a bump in the middle of the turn doing 50kp/h and the arse goes out in a hurry, Turn that same corner with no bump it's fine and smooth. One thing i have noticed is the roads today are harder with no rain they are dirty dusty and falling apart.

**88GreenVN** · 18-10-2006, 08:31 PM

IRS = tyre wear big time.
I get 40,000km from my TZ100 215/65 firestones in my VN and it dont step out going around corners bumps or smooth.

Get better tyres and put a bag of cement in the boot.

**1991_Vn2nV** · 18-10-2006, 08:44 PM

You dont just need money to get the IRS, but to mod with IRS as well. Tyre wear, suspension, rims... You spend much more money on these with IRS than you do live axle.

**4PLAYN** · 18-10-2006, 08:49 PM

Ok spose i stay live axel.

How rare/hard would it be to get a VN SS LSD rear end or just a normal LSD centre to fit the borg warner diff .... + would the open wheeler axels need to be replaced with others to upgrade to LSD?

Cheers

Adam

**adam69** · 18-10-2006, 09:16 PM

Just get a Vp with IRS and put your good gear into it.The IRS wont just bolt up,you would prob need to replace all the rear floor/boot section from an IRS model.

Yeah, but remember you can only keep the ass end stuck down for so long man, once it lets go, its lets go. When it does let go would u rather having a heavier ass sliding out, or a lighter one?

Thats a tuff one

But some foot and opposite lock would go good

But if i had IRS first on list Camber kit

, I'm lucky enough too not drive huge km in this car so it's more a fun car as soon as i can get another for us too use. But my brother might have a VN Calais for us soon or a Toyota Camry too belt around.

Last thing i want is a bag of cement in the boot lol

I just got it off a guy that towed 20 bags of them

A bricklayer.

But if it's a hard job and too much modification i'll save the money for some extra suspension work

Thats probably the smartest choice anyway. Might get me the L67 or something else in faster

**Emackulation** · 18-10-2006, 09:50 PM

I would leave the IRS till very last on the list, I think you'll be much more smug with the L67 in first, hehe.

**greenfoam** · 18-10-2006, 10:19 PM

The crapy half breed IRS is a still a bit better for traction than a live axle car over bumps around corners and perhaps even in a straight line, there are other issues with it though (not as strong, more expensive parts etc) so just deal with what you have and everything is good

The coolest thing about IRS that I never noticed untill the dude at the tyre shop took my car onto the hoist is the squat when you select a gear, that looks pretty impressive

**Emackulation** · 18-10-2006, 10:37 PM

I was told about the squat in my car before lauching too, they said it looks kool.
