Alignment - rear toe

[SimonB]

When I had new tyres on a few weeks ago, I got them to check the alignment. Here's the results:

 

front L camber -0.46

front R camber -0.55

front L and R toe 0

 

rear L camber -1.74

rear R camber -1.97

rear L toe 0.29

rear R toe -0.03

 

Now I know what the rear toe is supposed to be in mm from good old mkiv.com, but this was measured in degrees. The printout has the specs as between 0.05 and 0.25. So what effect is mine being slightly out likely to have ? Tyre wear seemed normal on the old tyres (i.e. inside edge first) and they lasted long enough. Is it worth correcting or is it such a small amount that it's not worth it ?

Just an observation, I'm not a geometry expert.

 

Assuming the readings are correct, I would expect a car set up like this to suffer from poor straight-line stability, cause by 0 toe-in (or out) at the front. The front tyres are not laterally loaded when running in a straight line.

 

I might also guess that the (nominally) half degree of camber at the front while having 2 degrees at the back would cause understeer becoming on-the-limit snap oversteer.

 

Does the car turn-in well when you're pressing on, or does it push?

[SimonB]

It turns in pretty well, bit of understeer initially, but Ok then. I've not had it snap into oversteer anyway. I though 0 toe on the front was the normal setup anyway ?

 

It doesn't really suffer from poor straight-line stability, although it does get a bit floaty at very high speed. I guess the problem is I've never driven another Supra, so nothing to compare it with really.

0 toe-in is normal.
