Rear subframe and suspension

The standard Mazda MX5 NC rear end is a well designed 5 link, independent unit mounted in its own subframe.  As the Mazda engineers went to a lot of trouble to design and develop a state of the art independent rear suspension I saw no need to try to re-think them and build up a whole new rear assembly for the Locost clubman.  Therefore, with a bit of design and fabrication the complete Mazda MX5 NC rear subframe was fitted to the Locost clubman chassis.
