Bracket Racing

Sports Car Club of America (SCCA) Washington DC Region (WDCR)

Mid-Atlantic Road Racing Series (MARRS)

2018 Sprint Bracket Racing Rules 

PLEASE NOTE: The Bracket Racing concept is a work in progress and the rules are subject to change.

Philosophy of the Bracket Sprint Racing Class: The intent of this race class is to establish close and exciting racing based on the lap time potential of the car and driver and not based on rule-bound car preparation that stifles creativity and drives up the cost of racing. It is also the intent of Bracket Sprint Racing to open the doors to competitors from other race organizations as well as to lower the barriers to entry in to SCCA Club Racing. For 2018, Bracket Racing is a MARRS home race only demonstration race grouping at Summit Point. Cars must adhere to the safety and racing rules of the General Competition Rules (GCR) as well as the bracket class rules as spelled out below. Scoring brackets within the Bracket Racing class are established based on a range of lap times. A break out into a faster lap time moves you to the faster bracket without penalty. Slowing to avoid a break out is dangerous in road racing and will be subject to penalty. Competitors are expected to drive at their full capability. The Washington DC Region will recognize the race winners in each of the scoring brackets with a modest trophy but the bracket racing class will not be a part of the MARRS championship in 2016.

Car Eligibility


Bracket Racing is open to any closedwheel cars that meet GCR class rules, MARRS Optional Regional Class rules, as well as any vintage racing, BMW club, Porsche club or other racing organization car that also meet GCR safety rules. Cars must have an SCCA tech inspection and receive a logbook that approves the car for Bracket Racing or racing under any other closed wheel SCCA class. Modification of cars beyond class rules is unrestricted as long as the modifications comply with the safety requirements of the GCR.

Driver Eligibility


Drivers must be SCCA members (full or weekend) and hold a license eligible for regional competition per GCR 3.1.2. As of February 2016 the GCR recognizes the full competition licenses of BMW CCA, FIA, HSR, IMSA, NASA, Porsche Club of America, SVRA and many others.

Roll Cage Roll cages must meet, at a minimum, the requirements under GCR Section 9.4 for Improved Touring.

Car Modification - Wheel, tire, suspension, brakes, engine, clutch, transmission, differential and aero modification are unrestricted as long as they do not violate the safety requirements of the GCR.

Fuel Restricted in accordance with the GCR.

Car Appearance Cars must comply with the neat and clean rule. Car class (B) and bracket number (1 through 7) shall be in accordance with the GCR. Graphics will be in good taste. SCCA logos must appearin accordance with the GCR. MARRS logos or any other required logos must appear in accordance with event supplemental regulations (available at registration and tech). Minimum weight stickers are not required

Car and Driver Classing Car and driver brackets are B1 through B7 in accordance with the table below. The driver initially picks a bracket that represents his ability with the car. Should a driver “break-out” into a faster class during qualification or racing, the car and driver combination are moved to the appropriate bracket during the qualifying or race session in which the breakout occurs. A breakout is defined as any lap time that is faster than the class minimum. The car and driver combination will remain in that bracket, or a faster bracket should a future breakout require occur, for the remainder of the race season.

For examples: Bracket B1 is any car and driver running faster than a 1:26.0. Bracket B2 is for lap times slower than or equal to 1:26.0 but faster than 1:27.5.

Groupings of Cars At the discretion of the Race Chair, Bracket Racing may be run in a single race group or may be split into 2 race groups. To minimize the speed disparity between cars on track, race organizer may elect to not run class B1 and/or B7. Race organizers are encouraged to order race groups in such a way to maximize the ability of all closed wheel classes to participate in Bracket Racing as a second race group for the weekend. Bracket Race groups are limited to 50 cars. Novice drivers and first time racers from other race organizations will be given a priority. All others will be placed into the race group based on a first come-first served basis.

Intentional slowing Intentional slowing on track to avoid a break out into a faster bracket is both dangerous and inconsistent with the spirit of bracket racing. If race organizers suspect that this has become a problem they may elect to ban the use of in car timing displays and the use of radio with the driver. Slowing to avoid a breakout will be subject to penalty.

Rain Scoring brackets are based on the dry track potential of the car and driver combination. Cars will not be reclassified based on rain.
