Ok I think I have this right but I'm not sure.

I have measured the camber with a straight edge from rim to rim using one of those I phone apps.

I have got the following:
Drivers side camber angles
Straight = -0.9 deg
20 deg Camber right= -0.8 deg
20 deg Camber Left = -0.7 deg

so caster = (CR-CL)*1.5 gives 0.15 deg caster

Passenger
Straight = -0.4 deg
CR = 0.3 deg
CL = 0.3 deg

Caster = 0 deg

or am I talking bollocks?

All of my suspension is standard wet and I have noticed that the tie bar is bent on the drivers side.

I guess these are rough and ready but give me an idea as the 20 deg was done with a card template so hardly science?

I run a supercharger and I don't care the TB is on the wrong side.

Sound about right, but no where near enough. What should happen with enough castor is you get neg camber gain on turn in, and pos camber on turn out.

Cool I know the settings I'm running are crap. Front suspension is the next upgrade...

Also the shorter the tie rods the more caster?

I thought increasing castor was to place the wheels closer to the rear, so you'd need to lengthen them. That's if I'm right.

Yes. Aim for around 4 deg as a start.

if you place the wheels to the rear more you will end up with the tea trolly affect very weird handling
go for 1/14 camber and 5/12 deg positve caster thants movin the wheels to the front this will give you more selfe centering of the wheel when coming out of the bends

watch thoug as caster affects camber and so on, it sort of sneaks up on you
mine is set at this and its fine
