The BMI conversion is a work of art. The only problem I forsee if you are coming from the FT car to the BMI is the motor mount. I don't believe the holes will line up in the Chassis. The BMI motor mount is dialed anyway. just get the kit and the mount and your in business. I know that Jason is working on shock towers and a center stand off to make the car even stiffer. One thing I forgot to mention in your email James is that the FT car is made with 2.5mm Graphite and the BMI car is 3.0 mm graphite. That makes a difference in the way the car handles.
