You can take a bunch of metal to a welding shop and they will weld it together for you. Then what???
Question is, do you and johnparts have the engineering and development to have a unit that performs as good or better than stock in regard to things like: ackerman, turning radius, roll center distribution under roll and jounce, caster change under compression/rebound WITH turning, anti dive, camber change, bump steer, SAI, etc, etc....
