Pro 2WD & 4WD

The Pro Class is where performance and lap times step up a level, due to the permissable use of slick tyres. Once the top-category for UK Time Attack and an arena designed to attract professional drivers and teams, the Pro Class is where constructors are able to push the limits of what can be achieved by tuning and modifying a road-based vehicle.

Whereas in Pro Extreme, chassis modifications and spaceframing can be carried out, Pro Class cars must be based on production models, retain OE suspension mounting points and utilise the manufacturer’s integral shell structure. They have the option of running slick and racing wet Pirelli tyres and whilst they can be fitted with sequential gearboxes and flat floors, aero cannot extent more than 150mm from the main bodywork.

Pro cars must be fitted with two seats and a full-width dashboard, have fully functioning lights, a minimum ride height of 40mm and operate within the blanket 105db noise limit. They may however, run alternative fuels, including racing blends and the addition of methanol.

Split into two sub-classes for two-wheel-drive and four-wheel-drive cars – although these can amalgamated if there is a parity of performance between the two drive-line configurations – Pro Class cars have to be built to Motorsport UK Section J regulations. This means they must comply with racing rules and be fitted with safety cages, a plumbed in extinguisher system, external ignition cut-off switch, in-date seats and five-point harness.

Drivers must hold a race national B competition licence (minimum) and wear HANS devices, in-date helmets, race suits, boots and gloves.

Those who sign-up for the whole season will score championship points and be eligible to win trophies for first, second and third places. Phased payment plans are available to make the cost of participation easier to manage. Entry is also available on an event-by-event basis for just £420 per-round.

Competitors will take part in all four 15-minute (minimum) sessions: Warm-up, Practice, Qualifying and the Final, with points awarded in the Qualifying and Final sessions and the finishing position in the Final dictating the overall results.
