Most GB4 cars are run by professional teams, but private entrants are also welcome. Great emphasis has been placed on minimising the cost of participating competitively. Costs are controlled by the following restrictions:

  • Sealed engines - may only be rebuilt by MSV's highly experienced service provider Mountune, who will also ensure engine parity
  • Controlled compound tyres for durability and consistency
  • Pirelli 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 provides 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

MSV has a comprehensive spare parts supply at its Bedford Autodrome HQ. MSV also sends a spares truck to each race and championship test, carrying an extensive range of mechanical parts and bodywork. Spare engines and gearboxes are also available, as well as electronic components.
