Do a search......................then do it properly!
Alter your top bones to increase your castor to around 5-7 degrees if you want a nice handling car.

If you want to get through SVA without making/buying another pair of top wishbones, try adjusting your tracking at SVA to give plenty of toe out and inflate your tyres to about 30psi.

Just don't drive too far with the tracking set to toe out.

Sva are getting wise to toe out methods and they do drive the car about to see if it feels safe.

Another thing to consider is your steering rack. It could simply be that the slipper has been adjusted too tightly, or maybe the rack has insufficient lubrication.

If the steering rack is fine and there is plenty of air in the tyres, you shouldn't need a ridiculous amount of toe out to get it to self centre.

Proper Castor............

do you want positive or negative castor? whats best for toe?

You want the top wishbone balljoint about 5 - 7 degrees rearward of bottom balljoint.

The risk of returning to sva without altering castor and using toe out, is that you are failed again.
It took me 3hrs to modify my top bones. I am sure that in previous threads that most 7's need the top of the upright to go 22mm rearwards to give the required castor.
Not only does this make the car stable to drive, you get a better feedback through the steering when un-winding out of corners.
