Understanding alignment sheet

[M3AN 4016]

With toe out front and rear you will have lower straight line stability... the car will want to move off that straight. To confirm drift you'd probably want 0* toe front and rear and a dead flat surface. What happens when you reverse with the steering wheel strait, does it drift?

Typically for a "sporty" setup you'd have a small amount of toe out at the front to aid turn in (whilst reducing directional stability) and some toe in at the rear to compensate for the drift induced by the front end.

^ I understand all of this BUT, the alignment sheet "looks" fine to me. It looked fine before and it looks fine now. BUT it still swerves left.

Im wondering if it is an inherent issue with this model vehicle or if there is something else wrong with the car such as tie rod/control arms or maybe a bent chassis.

Did the wheels get balanced when the new tyres went on? Also, do the reverse test if you can find the space, that will help eliminate a whole bunch of variables. 

If you're using assym tyres you can also swap the fronts left to right to eliminate balance or a damaged rim. 

Edit: assym tyres at the front will drag the car left or right depending on tread pattern because one tyre is always running "backwards". That also needs to be factored in. Doesn't matter at the rear.

Wheels were balanced. Not sure where I could do a reverse test and how safe that might be but will keep in mind when im out at 3am.

The assym tyre pattern argument makes sense. Didnt think about that. It is a FWD car also. But Ive owned a few minis now and this is the only one Im having an issue with at the moment so..

If you cant figure it out, and before you throw parts and money at it, take it to autolign for them to align as the place you have been going to sound like they dont know what they are doing.
