Yes, Ian, Tilly is right. lots of changes in one go can leave you not knowing what worked.

I'd always look and try tyres first. I use yellow mini spikes on front and rear. front wheels are wide or uncut.

If you were running new fronts, they do take a meeting or two to bed in.

I'd then try Neil's rear end tune. More often than not you are adjusting the balance of grip between ends to get the feeling right. Concentrating too much on getting rear end grip can leave you with an under steering car.

I'd then try a little softer spring and damping combination, then more subtle changes like a longer front upper camber link, less caster, a little bit of toe-out, more ackerman, and the upper shock position.

Most of these changes can be done at the meeting between rounds. Maybe you could rebuild your front dampers beforehand, or have a spare set built at home ready to go?

Make one change every run to feel the difference. Have a plan of the changes to make, and stick to them until you get the car doing what you want.
