get it set up very neutrally, then change it over time to suit your driving. start with the wheels parrallel with minimal camber and take it from there.
mine is set up neutrally now, but im going to be getting a touch more camber and possibly some toe out to increase turn in.

I run 1 degree toe in and 1 degree camber. The car is very stable.

The worst thing about Indy front suspension is lack of caster. It results in next to no self centring and not much steering feel.

In fact as standard the steering is pretty crap as far as feel goes.

I have modified my wishbones by replacing the bushes with rod ends, after seeing what other people on here had done, to give 5.5-6 degrees [it had about 3-4 as standard].

Yet to drive it with the new bones, but hoping for some improvements.

I would always run a bit of toe in a 7 chassis to pre-load the bushes slightly to remove slop. On 13 inch wheels, I would start with 1.5mm of toe out. This will give a nice fast steering response. If you run parallel, you will find the car becomes a little less sensitive to steering input.

It's just personal preference, but 1.5mm toe out (around 15 minutes if you work in degrees) gives a feedback I really like.
