Can any help me on the best if not a good suspension/ geometry setup for a classic Subaru. The car isn't my daily and will be used as a fast road/ track car. Not to worried about tyre wear as it also won't be used in winter.

Currently running bc coilovers and ad08rs all round, was thinking about white line front and rear arb's, anti lift kit and drop links and also hardrace pillowball arms but they don't have lateral camber arms? Would they make much difference? Is there anything else in missing

Also I'm not sure about if my top mounts on my coilovers have castor adjustment, how can I get round this to gain castor?
