Technical Matters

The series comprises cars which ran in the past with Bernie’s V8s or SR&GT whose co-operation has provided these simplified regs for 2019. They will be joined by cars like the Crosslés, MGB BCV8s, TVRs, Jaguars and from other invited clubs, all of whom must conform to the regulations of their club. The car must be an original, reproduction or replica two-seater sports car, GT or saloon car, the original model of which was built before 1st January 1994.

All cars except historic cars with FIA papers (Class H for pre-1979 Historics) compete in the power-to-weight ratio classes …

Class A 386 to 665 HP per tonne
Class B 311 to 385 HP per tonne
Class C Up to 310 HP per tonne

The rest of the regs in brief… Engines must be naturally aspirated, no sequential gearboxes, no traction control, no ABS or carbon brakes. Just big old school muscle race cars, and no Seven-type, or Radical-type cars. For advice on the eligibility of your car please email Cheng (cheng@thunderroadcars.com).
