The 360 Challenge’s performance capabilities were constantly honed over 15 months of testing and 6,000 miles on the track. The Challenge version has many modifications setting it apart from the normal 360:
Reduced weight by 330 lbs. Air conditioning, gear change heat exchanger, electric windows, sound deadening & interior trim were removed. The front & rear bumpers, exhaust system, windows, center console & door panels were replaced with lightweight counterparts.
Changes to the suspension include: new electronic damping system, BOGE shock absorbers, racing springs, aluminum suspension bushings and a thick 22mm anti-roll bar.
The cockpit features a Magneti Marelli digital dash readout which allows the driver to check performance data acquired by the on-board, F1-style telemetry system.
A number of modifications have been made for track use, including fitting a larger oil radiator and stiffer engine mounting bushes. Safety features include an automatic fire extinguisher system and FIA-approved safety fuel tank with a capacity of 22 Imperial gallons and two filler pipes for rapid filling.
