i have a 99 cxi hatch

so far i have

Tien SS (aus spec) with edfc
whiteline front strut brace
whiteline front and rear sway bars
new trailing arm bush from hard race

i am very keen on doing some track work now and then
so i was wondering if front and rear camber kits are a help?
rear strut tower brace?
extended ball joint (buddyclub or J's racing) will they help?

Any other ideas will be appreciated..
