Problem of keeping it as a bolt on kit is i dont think i can get the car low enough to work well with the new body. The car in the picture is sitting on wooden blocks to get it that low. If i can get it low enough to work with the body conversion i would consider making it a bolt on kit. My thoughts at the moment though are to make a complete shell and chassis. See below this is the height it currently sits at. I have seen 75mm lowering kits for the MX5 but still would not be enough.
