Seems any combination of S13 or S14 will do but will have to be trimmed depending on which S-body lower-arm you're using. S12 shortest, S15 longest.
If you're car is strictly for competition a longer lower-arm for negative camber plus toe-out may well be beneficial, giving sharp turn-in and varying degrees of oversteer, depending on how you want it to behave. If you could find a way to reduce rear negative camber that would help too.
It'll work the front tyres hard though.
Personally, I fancy S13 lower arms, with S14 lower balljoint, whichever steering arm set-up, S14 hubs (for the brakes) and S14 coilovers and a full Z31 rear set-up.
I don't want too much front neg. camber initially. I work in the trade so swapping the arms again in the future would be no big deal.
