Tyre Wear

[brad]

How on earth can an eccentric adjuster attached to the strut change the caster as well as the camber unless you have an A-arm with adjusters at the chassis pivots (like an old Merc)? I'm not questioning you, it's just I can't imagine what you are describing. If you could link me to a diagram or similar please?

Yes, those VS IRS were major fail, even on the later models with the extra link(s).

As you said, these are on family cars, so slight changes in roll centre don't worry most people. People seem much happier with "the adjuster is crap but will do the job" rather than "you'll have to live with tyre scrub / pulling / etc because there is no adjustment"

Explaining in words is really difficult, at least for me. The strut top moves in an eccentric fashion and eccentrics are not concentric, clear as mud? Sorry Brad I can't think of any other way to put it. BTW I am talking of a cam adjuster at the top of the strut.

OK, now I get you. Like a VB-VL Commodore.

From a practical point of view they were great. IIRC, Commodores came out with about 1.75 degrees of negative camber & equal caster. As the dampers gave out (they'd leak at about 30,000km. I used to do about 5 replacements a week. Got it down to 1hr), the springs would cop a pounding then would sag a bit. This made the camber 2 or more degrees & resulted in shocking inner tyre wear for most drivers. At least you could spin the tops & get the camber back to ~1.25. A little extra caster didn't do any harm either. Also, they didn't slip, unlike a cam on the lower control arm (like a Falcon).

Yep, just like the commode, I learned how to change the NS rack bush without removing the rack, must have done a hundred of them.
