V8's cause excessive wear 😁

Isn't 36psi a bit much? Ive MPSS and run at 30psi?

I find 34psi works best for mpss 285s in winter and 33psi for summer
but 35/36 for front 245s

Not wanting to sound pedantic but the vxr8 needs, what's generally known as, Full geometric set up.

Simple 4 wheel alignment really isn't even half the job. Although you probably meant full geo, right?

Four wheel alignment in its truest sense is little more than tracking. Rear wheel drive needs to account for the rear thrust angle. Or the rear will stear out side ways and the car will effectively crab with a ssiped steering wheel, unless the set up can guarantee a zero (dead ahead) thrust angle measured correctly.

Ok, anyone offering the full geometry service in Lancashire .

Have a look on www.alignmycar.co.uk

Check the wheels in motion site, they have franchises around about, or did have.

Pro drive too although mixed results with them.

Nigel langs also crop up. But not familiar with your area.



Often though, a catalogue of manufacturers settings and a hunter Hawkeye rig doesn't always mean perfect results. As it depends on the competancy of the operator, and the tolarences allowed by the manufacturer in the settings quoted.

Ultimately," in the green" isn't always a guarantee accross all marques. Although Holden seem pretty good going by various posts here. Vauxhall on the other hand .... Lol
