Can someone interpret these alignment readings please

[Alpinestars]

Car feels very frisky, and these were the settings before correction. Can someone help me identify whether this would have made the car more "oversteery"?

It's a rwd, mid engine car.

Thanks

Of course it depends on the car, but my mid engined Europa needs to have some rear toe-in for stability. Having parallel or toe-out as you have will make it feel unstable, so maybe that's a potential cause ?

If they were before, what's it set to now ?

Small front toe adjustment required to straighten up the wheel. Apart from the front toe, all is well. Your instability is being caused by something else.

Total rear toe is in tolerance. You wouldn't try to rectify the fact that the right rear is toeing out, you'd just compensate on the front axle.

This is where it's ended up. Would the difference between the right and left not make it feel "out"?

It now looks balanced, but I've not had chance to drive it to find out what difference its made.

Yes, there's more green ink on the page but it was only out by a few minutes to begin with. I wouldn't expect it to feel drastically different. If anything, it'll feel pointier at the front as you have less total toe in at the front.

Anyway, drive the thing and let us know!

Thanks, that's very helpful. The skittishness was probably down to cold tyres. It's still a pretty lively car though, and the steering feels a bit lighter on turn in, but that could be my imagination.

No worries, I don't know much about your car but I do know the geo process reasonably well.

You have two minutes less toe-in at the front now and the toe-in and castor contribute to the steering 'centering' force which causes the car to want to go in a straight line- so basically it probably isn't your imagination, rather the car is actually resisting change of direction less, hence my suggestion that it might actually feel 'pointier' at the front. The adjustments elsewhere were small enough that you wouldn't expect them to notice that much, but the rear toe and camber are better now. Looks a good job to me.

If the car is still overly 'skittish' I'd start looking for worn suspension components or mismatched / worn / old tyres.

How old are the tyres?

Have seen a lot of laser alignment machines figures being totally out when set-up using the "old fashioned" methods that 95% of race teams still use so I would take this into consideration.
