Or solid ditchfinders

4) apologies I should of mentioned this earlier, but there is what I'd call excessive tyre squeal under hard cornering. Long before it looses grip, although under steer arrives before over steer due to the wider rears.

That about sums it up. Squeal is obviously excessive slip, which equals wear.

Given your wide rears, the car will understeer - all Omegas do, even with standard tyres sizes - which will aggrevate it further, particularly coming out of the corners.

Due to working in MK, I scrub out the outside shoulder of the NSF all the time, as most of the loading goes to that wheel around roundabouts.


If you drive that hard, you probably need more aggressive camber, possibly approaching the Irmscher recommendation (maybe not quite that much). But when I ran 1'30, I found straight line stability awful (although that particular car has never had good straight line stability).

Somewhere, I fear there has to be a compromise if you want soft tyres and drive them hard, yet still want durability.

There's a video on you tube, by top gear Australia, showing the new vxr8 on 20" inch low profile wheels and tyres. It's an option available over the standard 19" wheels.

The tyre squeal is much more pronounced on the larger size. You said yourself they give a good audible warning before letting go.

So the squeal could be understeer. It could be excess toe/helped by less toe. It could be wheel size/lower profile tyres.

But obviously squeal isn't good.

In a long sweeper, as described to TB, if it stats to squeal, boot it and the squeal goes, I guess as the front is unloaded...?

It could be excess toe/helped by less toe.

I doubt any toe setting that's valid would affect the amount of squeal when cornering
