British GT: what you need to know
For more than 25 years the British GT Championship has formed an intrinsic part of the UK’s national motorsport fabric. But, having undergone a number of changes throughout those that quarter-century, it’s difficult to envisage an era more competitive than the current GT3/4 format.

• GT3 and GT4
• Cars not homologated as either GT3 or GT4 can run as Invitational entries at British GT’s discretion
• GTC remains a legal but currently unused specification
• Rules include performance balancing and handicap weights
• Pro/Am driver crews are the bedrock of British GT. These consist of professional drivers graded as Silver (or higher) and amateur/gentleman drivers graded as Bronze.
• Crews consisting solely of Amateur or Silver drivers may also enter, although the latter’s car will be carefully balanced by the GT Bureau to ensure it competes at the same pace as Pro/Am line-ups, thus allowing both to challenge for victories.
• Silver and Gold/Platinum driver pairings are not permitted.

Sunoco Fastest Race Lap of the Weekend Award
Awarded to both the GT3 and GT4 driver who sets their class’ fastest race lap. Weekends comprising two races will still only reward the overall fastest time in both classes. The driver with most fastest laps at the end of the year will be crowned at the end-of-season prize-giving.
Professional Motorsport World Expo Team of the Weekend Award
The Professional Motorsport World Expo Team of the Weekend Award will be offered to the outfit that has gone above and beyond or produced a stand-out act during each 2018 British GT event. This, amongst other considerations, might include overcoming a particularly difficult technical issue, executing an innovative race strategy to perfection or achieving an unexpected result in the face of adversity. The award is open to all full-season teams competing in both GT3 and GT4. A trophy will be awarded to each winner at every round before one overall ‘champion’ is crowned at the end-of-season prize giving ceremony where their sporting attitude, dedication and spirit will be recognised.

PIT-STOP AND DRIVE-TIME REGULATIONS
In races lasting one hour the top three finishers in each class from the previous round must respectively serve an additional 10, 7, 5 econd success penalty during their mandatory pit-stop. During races lasting two hours or longer the top three finishers in each class from the previous round must respectively serve an additional 20, 15 and 10-second success penalty during their mandatory pit-stop.
Competitors must make at least one pit-stop during all British GT races. During the Silverstone 500, the season's only three-hour race, competitors must make three mandatory pit stops.
All cars are subject to a minimum pit-stop time. This starts as the car crosses the pit-in line and ends as it triggers the timing beam at pit-out. Anyone found to be under this time must serve a stop/go penalty to the same value as they were under time (eg 10secs too fast in the pits equals a 10secs stop/go penalty).
During one-hour races the minimum time a driver can spend behind the wheel is 25 minutes. This minimum time rises to 60 minutes for Am/Starting drivers in races lasting two hours.
Failure to adhere to these time scales will result in a stop/go penalty or additional time added post-race.
There are always four qualifying segments determined by driver grading and class…
1x GT3 Am
1x GT3 Pro
1x GT4 Am
1x GT4 Pro
…but their significance depends on the number of races being held that weekend.
2x one-hour races: each car’s Am and Pro driver’s best individual time will determine the grid for Race 1 and Race 2, respectively.
1x 2 or 3-hour races: each of the Am and Pro’s fastest lap times are combined to determine the starting order. The lowest combined time takes pole for each class. The Am will start the Race.
Each of the four sessions last 10 minutes.
Classes are split, meaning GT3 and GT4 cars do not run at the same time.
Drivers must complete two timed laps (not including in and out laps).
