The transmission and differential all have the correct gear ratios and final drive ratio for automatics as well as manual transmissions along with offered options of limited slip and open differentials.Ġ-60 times and weight of the vehicle are close the real world values. It has the correct oil capacity, radiator fluid capacity, radiator size, fan speed, fan clutch engagement etc. The engine (428 CobraJet) has all the correct torque values gathered from several sources. The biggest challenge was to find spots on the body and frame to attach the suspension and then tweaking values to make it handle like a mustang, otherwise the rear was sagging and bouncy over bumps and dips significantly under heavy acceleration. The rear suspension out of the Burnside was put on the mustang. To solve this problem, a “transplant operation” is done. The moonhawk’s rear suspension included coil springs whereas the mustang has leaf springs. In the Jbeam, this simply means multiplying the steering factor by -1.

With the current setup, the car’s steering is reversed since the whole steering system is now aft of the steering box which means the steering box gearing had to be changed so that its output is reversed. When it comes to the jbeam, the tie rod nodes which connect the tie rod to the hub (fh3r/fh3l) had to be placed at the back of the hub (with proper triangles and beams). The 1968 mustang’s steering system is located aft of the steering box and came with a tie rod attached to the back of the hub (aft of the Z-axis of the wheel), whereas the moonhawk’s steering system is forward of the steering box and tie rod is attached to the front of the hub. The steering originally came out of the moonhawk however it was heavily modified to a completely different setup. Suspension and steering also had an overhaul. The Jbeam is based off of the Moonhawk but several major changes were made to fit the body and panels of the mustang. Different variants (stock, race, fastback, convertible, auto, manual.)

Alot of research and countless hours of observing how the car rides in videos on youtube was put into this project.Ĥ. This is the 1968 Ford Mustang Shelby GT500KR.Ībout a year and a half of work has gone into this mod to make it crash and handle just like the real thing.
