TA22 + Sigma Lower control arms

[sleeektoy]

Ok - bit of background...

I have a 1972 TA22 Celica that i have decided to flare/spoiler/jacket

I have been playing round with the front suspension setup to see what sort of results i can get in terms of looks/practicality with fitting the flares

I have struck a bit of a problem that i'm hoping someone can answer.

I have Fitted a GH sigma bottom arm, which fits with surprising ease.
-same dia x-mbr bolt
-same radius/caster arm bolt positioning/spacing
-8mm different hole positioning for swaybar - (considered negligible)
-50mm track width increase per side (brings tyres/wheels nicely out into flares) 8O

I have RA28 struts with koni coil-overs which have all the usual adjustment
I have adjustable top mounts

THE PROBLEM!
Since fitting the bottom arms i now have approx 4-4.5 deg negative camber
Whilst this looks cool and fits perfectly with the flares i don't like the chances of survival of the inside of my tyres.

left is factory TA22, right is GH sigma

I have heard the *A60 supra struts induce positive camber into a TA22 if fitted, does anyone know the angle difference in the RA28 to *A60 kingpins?
A possibility this could fix my issues?

possible
i also found rt132 corona struts have more kpi compared to ta22, another option to try
there was a thread around with the differences between different struts in a kind of table format
have a look for it in the search

after a bit more searching - ive found it - thanks

+3 deg camber by the sounds of it.

maybe ill try it as-is and see

BTW - heres a pic of the lower arm fitted
