Title: Wheel alignment
Post by: OldGMHolden on October 04, 2011, 01:09:06 PM
G'day all,

Can anybody help me with a wheel alignment query?
I have a '59 FC which has been lowered 50 mm with new springs, bigger sway bar, and radials on 6" rims (standard king-pins).
My local wheel alignment bloke feels that the standard settings for wheel alignment should be OK, as per the workshop manual.
I remember reading some years ago that the toe-in needs to be altered when fitting radials to a car which normally had cross-plies, but I can't remember the exact details.
I also think I read that other adjustments may be needed due to the lowering.
Do any members have experience or thoughts on the matter?
C'mon you Gurus!!

Cheers,
Gaz.

I'll have to follow the answers to this one, I can't see how radials can affect a wheel alignment. All the old cars I've had (lost count) would have had crossplys as original equipment, and usually its the first thing I change is to go to radials and I always have had alignments done at the same time without a problem.

If you want a challenge try driving with radials on the front and crossplys on the back, I did this once when I was young and broke (apprentice wages in the seventies) so I thought I'd get them as I could afford them. Couldn't drive the bloody car until I could afford radials for the back :D :D :D

G'day all,
I found the article which I thought recommended different alignment settings for radials, and I stand corrected.
I can only attribute this to Ol'timers Disease.
However, it DID say that realignment would be required in all cases of a (old Holden) car being lowered, as there would certainly be changes to the geometry due to the unequal length wishbones now resting at new angles.
