Self Centering - lack of

[mr henderson]

5 degrees sounds like a lot to me, what does that work out to in mm?

[AshG]

it should self centre at the proper settings which should be between 0 and half a degree of toe in.

the wording in the manual says it should show a degree of self centering above 10mph.

when they tested mine he put it on full lock at stand still and started speeding up. if the steering wheel moved and the car starts trying to come straight then that's fine for a pass.

Shouldn't need more than 1/2 degree toe in on any car. A little toe out may help for the test but 5 degrees

The problem is the book doesn't give the car hardly any caster so there's virtually no self steering.

Need's a revise of the lower front wishbone design to increase caster and thus more self centre, then the mushrooms could be put to the position they should be.....

I redesigned the Locost upper wishbones 7 years ago, to increase the self centring on Cortina knuckles.

I cannot understand why the Haynes design didn't do something similar to ovecome a known problem with Sierra knuckes.

I had a further mess about today, if I now set the wheels to about 0 degrees toe it does still self centre but not as well as with a degree or two of toe out. Dialing in a bit of toe out makes a big difference. I also experimented with tyre pressures but got less marked results from that. To my mind it now complies with the IVA rule with it set so that handling should be Ok so I am a happy camper.
Thanks to all those that replied.

My new garage service has just purchased traditional laser 2 wheel tracking equipment. Not new fangled 4 wheel computer programable stuff..

So They whould be able to set my tracking up nicely for me when I am done .

Traditional but with lasers? How traditional is that?

More to the point, I think 4 wheel alignment is superior, especially for this type of car.
