i dont have konis, so i couldnt tell ya...but i have Gaz coilovers and have 325 front and 175 rears (as advised by others).....but i think the rears are too soft (so i adjust the struts)......i'd say on my set up 300 front and 225/250 rear.....but thats just me....suspension is a twat to sort out as its personal taste..........
