The car feels a little compromised on the prodrive settings that were in the box with the springs, so its going in for alignment again today.

I'm struggling to find any other settings though- I've found these on NASIOC for the RB320- what do you think?

Front Camber -1°30’(Maximum negative on adjustment)

Front Toe-in (Total) 0°06’

Front Caster 3°00’ (Referential value)

Rear Camber -1°30’(Standard Subaru)

Rear Toe-in (Total) 0°06’

Thrust angle 0°00’

 

I would try for more castor than that if you can get it on the car.

Also, zero toe in/out.
