not sure if its height adjustment or just a novel way to support the top of the spring and shock, the A arm angles seem to be wrong and the inner top mountings will need to be raised and moved out towards the wheel to put the A arms on the same plane to stop the steering angles from changing with suspension movement I'm trying to work out the correct angles before I start changing any thing, I may have to change a few things and test the movement without the springs installed. all good fun
