The car runs on a Motec M800 engine management system with full data logging.  A Motec controller also maps the center differential locking characteristics.  An AIM dash is used with warning lights.  The Motec allows full throttle no lift upshifts.

The KAPS transmission uses fast shifting dog gear engagement with a sequential  shifter.  With the Motec no lift shifting and KAPS sequential transmission, shifting is almost instantaneous.  The turning brake is hydraulically activated.

The cage ties the entire chassis together.  Rally cages seem to be more optimized for rollover and chassis stiffness than side impact.  Look at all the triangulation.  A Sparco seat and steering wheel are used.

You can see how the cage is designed to spread rollover loads evenly throughout the structure.  Rally cars can flip violently.  A well built road racing cage is much different, it is designed to take side impact more and roll over less.
