Danny Thompson's Challenger II Land Speed Record car.
At Speedweek in August 2018, it is officially the fastest piston engine / wheel driven car on planet Earth, with an average speed = 448.757 MPH.
Speed clocked at the end of the speed traps = 459 MPH.

The original Challenger2 shape and layout was basically good, however it needed updating. Gibson engineering and design included: new steering, front suspension, and drive line,
3 disc "glide" style clutches, gearing, exhausts, carbon brakes, engine air intake ducting, Gibson Wheels, and aerodynamics using aircraft stability and control algorithms.

With new greatly extended tail and the overal body shape, the CG vs CP locations show good stability margins.

Gibson Racing Wheels custom made for Challenger2.
2-piece wheels were spin tested to 560+ MPH.

Gibson with Seth Hammond's Lakester. Video cameras had been mounted
to temporary framework to record air flow characteristics during test runs.

Gibson was able to use his aerodynamic engineering with the design of laminar
flow front wings which provides aerodynamic balance with very low drag.

The car is ready to run. Note upper and lower tail fins
designed by Gibson for yaw stability and low drag.

The car currently holds the SCTA records for AA, A, and
B/Fuel Lakester (over 320 MPH), and the AA, A, and B/Gas Lakester records.
