1) Mark on the track rod a line so you know where the top is.
2) Unbolt and turn the track rod by 1 turn so it move out from the track rod end - this moves the wheels outwards at the front.
3) Take it for a quick drive forwards and back and see how it feels. Ours felt a bit more neutral going back ward but still no auto centre.
4) Repeat if needed, we did with a 1/2 turn. Now backwards wasn't auto centring much at all and forwards was doing it a bit, but not quite enough.
5) Repeat if need, we did an extra 1/4 turn. Now the auto centring forwards was very good. Still slightly loose around the middle but 1/4 turn and it runs nicely back into line.
This has a made a huge difference to the handling feel. The feels nimbler into the bends and is easier to steer.
I've also moved my seat a notch forwards which is less relaxed but gives me better control.

Spooky, i've been doing the same experiments today.
(But of course, I am not allowed to drive on the road yet
)
Toe-in just made the lack of self centering worse and worse.
I ended up with 3 whole rotations toe-OUT from my 1/2 degree
toe-in position!
The steering is now nice and light and I get some self centering.
I had to stop when my engine started to cough and splutter. It felt like fuel starvation so I opened up my K&N fuel filter which was full of very fine crud. I also checked and cleaned out the filter in the facet pump but not much in there.
It seemed to run fine afterwards but haven't run it long enough to really tell.
I also checked my exhaust noise with read 98dBA at 4500rpm on my eBay sound meter, so hopefully that will be OK for the SVA.
Now just 15 things on my list to do before SVA.
Wheel Alingment
Linear Mode
