got an email today from the boys at kw right they said to me that because i am running v1 they can supply a universal HLS2 which is only for the front...
They said you will have to change the housing of the front strut as there will be not enough space for installing the HLS2. In future they will change the housing on coilovers so that customers only have to install the universal HLS, amd not have to change the housings.
HLS4 is not possible as on the rear axle you don’t have a strut but spring and damper.
They also said the delivery time for universal kits and new struts is approx. 2-3 weeks
So iv told them interested and waiting for a figure possible group buy for kw owners if the price is right
