I just had tracking done and got a readout from the machine. Toe-in is now 1mm per wheel all round (except the rear left which needs shims). Does anyone know what sort of camber values I should be seeing? Mine look a bit funny - could mean a bent control arm or frame?
I have Ed's front springs if it makes any difference.
I am sure that the tracking should be 3mm toe in per wheel with front height set to 140mm as per Tech ST-34-1/82. (140mm height is with lowered springs. If you have oem springs then the front of the car has to be weighted down to get this height!)

Toe In 3mm per wheel (front and rear)
Camber 0 to 0.5 deg negative
On my car the front left wheel was 0.1 deg neg camber
front right wheel was 0.5 deg neg camber.
The rear wheel alignment is v important as if not correct to centreilne it will cause rear steer. (i.e. set the rear wheels with thrust angle as close to centreline as possible before even doing the front).
Let's hope it isn't a bent chassis !

Hi Rob
When you say it looks a bit funny , what you mean ... perhaps a pic would help?
I mean it looks funny on the readout. It's not enough to be visible by eyeballing the car. Handling also seems fine (it was very squirrely before).
Rear axis is perfect, apparently. I don't think the exact amount of toe matters too much, so long as it's toed in and consistent.
Camber values I'm getting are -1 degree on the rear left, -2 degrees rear right, ~0 front right and +0.1 degree front left! Those adjustable control arms look interesting, I'm tempted to get them when I get new rear shocks.
Are you guys having fun in the ice lately? It's like driving a caterham.
The camber figures are nothing to worry about really.
For an old car having the camber to within 1 degree is next to nothing.
Did you polybush all of your suspension or did you put new rubber in ??
Reason I ask is that the rubber has a different compliance to the polybushes.
Old rubber can put the suspension out too.
Post the printout of the alignment if you have it.

ps I would still set the tow in to 3mm per wheel but that is me.
When I had mine done last year they didn't use mm, they used 'minutes' or something. I thought that was to do with time not angles! :lol:

No Dan, you are thinking of the AGM :wink: LOL
Hope you get it sorted soon Rob!

I just did a quick google. Apparently a minute is 60th of a degree. I'll have to dig out my sheet and see what readings mine was at.
So 5 minutes is 3 Degrees?

5 minutes is 5/60th of a degree.

Blimey Ben your worse at maths than me :lol:

No, these are the 3 degrees:

Thats a good link you've found there Ben.
Now how do we convert mm into degrees? NickT said the toe should be 3mm, but where is that 3mm measured?
