Hi, it depends what you want…. Coilovers give you full height adjustment, in summer slammed and winter up a little. Also big improvement on handling.
Suspension kit, great also for handling but only fixed height, if you want it lower in 6 months time its false economy to buy coilovers later on.
I can offer FK Silverlines at very good prices. lowerks.com is not yet finished but all will be there when its running. I run FK Sport edition plus which is a highsport with damping. Pics on facebook. Also the height on facebook has 20mm left up front and 50mm on rear. FK are the lowest you will find really.
