coilovers?

Do the rears on the V3 kit have just one adjuster for damping or two? Single adjuster would suggest its V2 on the rear, pair of adjusters would suggest they're V3 on the rear
 
They are V2's on the rear. I noticed this when I was looking at all the coilover options and spring rates etc.

V3 units are coil over damper.
 
personally i would go for H&R coilovers as KW's dont go any lower than the H&R springs i fitted first.
H&R coils have much more adjustment.
 
Well you drop drop it too much which H&R allow you may be throwing the geometry out (IC's, RC) though the added stiffness may be of use on the track. Personally for road use the KW can drop it more than low enough and provide a better ride, they are a better all-rounder imo.
