The collaboration between MMI and JRi goes back to the creation of MMI and the early model Mustang line. We developed all our coilover systems utilizing JRi shock technology. With the S550 Mustang platform we have returned to utilize the JRi shock platform with our proprietary valving to produce a ride that is comfortable on the street while allowing the driver to push the vehicle to its limits.
