hey mate i wouldnt preffer kingsprings have had them before and they are pretty soft, also casue shocks to die out more quick, im running kmac springs in the s2k, sits good isnt too bumpy but it handled better when it was stock, know my shocks are starting to go i wish i just got coilovers, that way i could also adjust the ride hieght, its probally well worth getting coilovers just dont go full into then like fly said just get some bit basic unless your going on the track.
