IRS seems to give much better turn-in, smoother ride, and handles bumps better. It doesn't tend to skip sideways as readily if you hit a bump mid-corner. It also gives better traction if you are giving it heaps of boot going through a turn - eg, turning out of a driveway or side road.

I wouldn't say that the absolute cornering limits are any higher than with a live axle. And, in theory, IRS has more wear points (bushes, etc), so should develop play sooner than a live axle would. But my 2001 AU2 XR6 VCT with IRS has no suspension slop at 250,000kms+, so maybe that's not an issue in actual use.

I believe the common AU issue of top shock mounts collapsing affects both IRS and live axle equally, but I could be wrong.

I love the IRS, and would much rather have it than not.


Cheers that's the response I was looking for, an actual owners opinion!

I might try and test drive both to make my decision...

The extra bushing and extra weight is what would turn me off an IRS model but if as you're saying they're a more comfortable ride and handle a bit better I may be persuaded.

Dons Ghia is IRS. Its certainly not as waggy in the tail on a set of bends as a live axle car.
It is more composed. Personally I don't really like it.
Im used to driving a car that will happily oversteer. That's how I learnt to drive.
Dons car handles like its on rails and rides really nice. Myself I get bored driving it as it is so comfortable and does everything so well.

More people paid for a ride in a VT commodore then an AU Falcon so the VT is superior.
Based on that fact my Mum is the best around!

Irs definitely takes the boat feel out of the Falcons.they definitely drive much nicer provided everything is tight and unworn
