  • Carbon rear extractor
  • Front lights replaced by NACA air intakes
  • Carbon rear wing
  • Quick Refuelling devices.
  • Lateral side skirts

  • Engine allowing a maximum power of 540 HP
  • Air jack lifting system
  • Plexiglass side windows

  • Front baffles designed in the wind tunnel for better ground effect and brake cooling.
After two racing seasons, the owners had the opportunity to have his car converted for Road use with European or American Standards, or to adapt it to enter National (IMSA) or international GT Championships.

The plan was to built as many as 36 for the racing series. Only 1 was ever built.
