Good morning, I am an autograsser and race a 98bhp MA12 k10. And coilovers are readily available for k10 Micras (through sources I'd know from racing). And not overly dear either, I think the backs are 250 for the pair and fronts are in around 300 for the pair. Hope this helps. Oh and btw, coilovers are brilliant and are just a straight swap for your standard struts
