The GB4 cars are run by the teams themselves or by private entrants. Great emphasis has been placed on minimising the cost of participating at a very competitive level for a season. Costs are minimised by the following restrictions:

  • Sealed engines - may only be rebuilt by MSV's service provider
  • Controlled compound tyres for durability and consistency
  • Tyre supply is restricted to six new slick tyres per event
  • Standard pump fuel for testing. Race fuel provided by Sunoco with strict compliance controls
  • Two-way adjustable dampers, sealed and supplied by Oram

Car operation support

A dedicated teams area on the GB4 website will provide access to the latest technical documents, bulletins and updates.

Systems support

At every race event and championship test, MSV provides support engineers to ensure that the cars, the engines and all the electronic and mechanical systems are functioning correctly. Support will be available to drivers and teams to answer any questions or solve any problems.

On-board video

Every car features a front facing AIM Smartycam GP HD on-board video system with CAN data overlay.

Spares support

Apart from offering a comprehensive spare parts supply service between events, MSV sends a spares truck to each race and championship test, carrying an extensive range of mechanical parts and bodywork. Spare engines and gearboxes will also be available, as well as electronic components.
