Singer doesn't necessarily have to be your go-to source when it comes to restomodding a Porsche 911 as UK-based Theon Design will also build your dreamy sports car. This 964-gen model started out in life as a Carrera 4, but now the engine's output is routed only to the rear wheels. It uses a six-speed manual gearbox modified from a transmission used by the newer 993 model and also gets a limited-slip differential for better traction.
