Front view geometry input please

[CoryM]

Hey guys,
Fiddling around with some front suspension geometry (front view) and am looking for input.
Here are some specs:
Building a "Locost" aka Seven (caterham wannabe)
Less than 1500lbs wet
200bhp V6 powered
Probably end up being a bit front heavy
4link, Live axle rear. no roll centre height set yet.
205/50r15 street tires
54" track
90" wheelbase
9.25" tall spindles

Static camber -1.5 degrees
Outside wheel camber -0.5deg @ 3 degrees roll and 1" of lift.
Inside wheel camber -2deg @ 3 degrees roll and 1" of lift.
Static Roll centre height 2.75"
Lateral roll centre movement 1.44" towards outside tire @ 3 degrees roll and 1" of lift.
Static Swing arm length 101"

What I am wondering, is how much inside wheel negative camber can I allow? I can't find any specs for it, but it seems like it could be better. As well you you think I would do better to reduce the swing arm length a bit more to try and reduce the lateral roll centre movement? I have fiddled around for a while, and this is getting to be close to the best compromise I can come up with.
My aim is first, have a predictable car, and second not have an understeering pig. For the later maybe a lower front roll centre would be wise?
Thanks for any input.
