I've got BC RM coilovers and have tried a few different alignments. Mine's a 97 with the later suspension so you might need slightly different settings. Here's my experience:
Front:
Tried 1.5mm toe out per side. Turn in was noticeably sharper, especially at higher speeds. Even just on the drive down to Wakefield on the freeway I noticed lane changes happened much quicker and required very little steering input. Actually had to concentrate a bit to keep it going dead straight. Inside edge of the tyres got smashed even though I was at the track almost every month. I wouldn't got more than 1mm toe out per side, maybe even less if you're not tracking as much.
Camber I think something like 2-2.5 degrees would be good.
Rear:
I started with 2mm toe in per side. Was nice and predictable. After a few bumps and spins it somehow ended up at 0mm toe both sides. Still handled well.
Camber started at 1.5 degrees or thereabouts. No where near enough. The outside shoulders were hammered after 1 track day. I bumped it out once or twice more and probably ended up at around 2-2.5 degrees which seemed to work.
I'll be going for another alignment soon once I pick up my semi slicks. Here's the settings I'll go for:
Front
Toe: 0.75mm out per side (1.5mm total toe out)
Camber: 2.5 degrees
Rear
Toe: 1mm in per side (2mm total toe in)
Camber: 2.5 degrees
I'll keep a good eye on tyre wear after the first event and make any changes as necessary but I think it should be pretty close. Main thing I'll be watching for is outside shoulder wear due to incorrect camber.
For the older rear suspension I think an extra couple of mm toe in at the back would be needed. If you're running street tyres, 2 degrees camber should be enough.
