Pros and cons?

Moving the front wheel forward leads to:

More camber on turn in = higher cornering speeds
Less static camber = more straight line grip.

Heavier steering.

Given that modern assisted steering is often a bit too light (ok a bit of a generalisation!) it seems like a win-win situation, what say you? What have I missed? Downsides?

When I enquired about increasing the caster on my EP3, the guy doing the setup said it made the car quite twitchy on the road, and as I weren't racing it/tracking it, not to bother...

that seems counter-intuitive

Camber on most cars is built into the hub carrier
Move one thing and others will also move

Increasing castor makes the steering self centre more strongly and gives you more negative camber when the wheels are't straight. It also makes the car more stable and gives the steering less "clarity".

A modified rack orifice/spring assembly is also an option to consider though it's probably more involved and harder to reverse. Maybe try it on a spare rack?
