I run Standard issue LOW 180b kings on the front but have cut the soft section of the coil to lower eyebrow height to 320mm. if you leave the progressive soft section in eyebrow height is ~350-360mm. I run Munroe Gas-GT dampers front and rear.
Rear springs are unknown stiff standard height units I picked up for $20 on ebay, that I've cut to give a 320mm eyebrow height. I've used catalogue spec kings in the past as well and they've been perfect on a daily. There are some pretty good deals on ebay for front and rear kings or 180b's at the moment.
Eyebrow height (if you don't know) is the distance between the hub centre and the lip of the guard.
P.S:This is a 320mm eyebrow on a 180b rear running 15x7 +20 rims with a 215/50R15 tyre on mine
