Thanks Graham. I pre-empted your suggestion and answered my own query with this image supplied via Dan at KH.
He assures me I will get the 5 link system with coil springs as shown above as well as rear disc brakes, although your comments on current builds makes me doubt the latter now unless you can make out such in the image. Certainly the spec sheet for my build makes specific mention of 5 link suspension including panhard rod but doesn't mention any brake options other than front reaction arms
