i'd say if ur planning on 5+ hill climbs plus extra curricular weekend action then 8/6 combo is decent, ive had the same spring rate AJPS coilovers and im yet to get to the track,
but its all personal opinion i know of some1 running i think 11 or 12kg in the front of an 86 and was daily driven and they liked it, so just get the norm spring rates and because there coilovers if u decide too stiff/soft u can change the springs
