Sprint Bracket Road Racing
Any Tire, any motor, any suspension
2018 SBRR Series Rules
PLEASE NOTE: The Bracket Racing concept is a work in progress and the rules are subject to change.
Philosophy of the bracket racing sprint 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 the Sprint Bracket Road Racing (SBRR) series 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, SBRR is a MARRS home-race only race grouping at Summit Point. Cars must adhere to the safety and racing rules of the General Competition Rules (GCR) as well as the SBRR rules spelled out below. Scoring brackets within a SBRR 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 and 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 SBRR series classes will not be a part of the MARRS championship in 2018.
The Sprint Bracket Road Racing (SBRR) series is open to closed‐wheel cars that meet any of the following: SCCA GCR class rules, MARRS Optional Regional Class rules, Vintage racing, BMW club, Porsche club or other racing organization that also meets GCR safety rules. Cars must have an SCCA tech inspection and receive a logbook that approves the car for SBRR 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.
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.
All required driver’s safety equipment must be worn at all times while on track. This includes but is not limited to driving suits bearing SFI 3.2A/1 or higher; Snell rated SA2010 full-face helmet; head and neck restraint system; fire resistant gloves, socks and shoes – See GCR Section 9.3 for full requirements. Roll cages must meet, at a minimum, the requirements under GCR Section 9.4 for Improved Touring.
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.
Restricted in accordance with the GCR.
Cars must comply with the neat and clean rule. Number panels shall be sized in accordance with the GCR. Class identification shall be as follows; car class (B for Bracket) followed by the SBRR class identifier (#1 through #7). Graphics will be in good taste. SCCA logos must appear in 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 typically B1 through B8 in accordance with the table below. The initial bracket for each race is determined in qualifying. Qualifying grid order is on a first come first serve basis. The grid for the first race of the weekend is determined by the fastest lap in qualifying. Should a driver “break-out” into a faster class during racing, the car and driver combination are moved immediately to the appropriate faster bracket. A breakout is defined as any lap time that is faster than the class minimum. The car and driver combination will remain in the fastest bracket that they attain for the remainder of the race weekend. The grid for the second race of the weekend is based on the first race finish order. Car and drivers that do not participate in the first race of the weekend will grid at the back of the pack.
|LOW LAP TIME||CLASS BRACKET||HIGH LAP TIME|
For example: Bracket B1 is any car and driver running faster or equal to 1:14.99. Bracket B2 is for lap times from 1:15 up to 1:17.99.
groupings of cars
At the discretion of the Race Chair, Sprint Bracket Road Racing (SBRR) may be run in a single race group or may be split into 2 race groups. Race organizers are encouraged to order race groups in such a way to maximize the ability of all closed wheel classes to participate in Sprint Bracket Road Racing (SBRR) 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.
This is racing and not time trials. Race scoring is based on your finish position within your bracket. Positions are based on your race finish order. If there are 5 cars in bracket B3 then the finish order will determine 1st through 5th place in that bracket. If one of those cars “breaks out” into the faster B2 bracket they will immediately be moved to bracket B2 and their finish standing will be based on their finish order in the new bracket. A car could cross the start/finish line, break out and move from 1st place in B3 to last place in B2. Winners in each bracket of the feature race on Sunday will receive a trophy.
Intentional slowing on track to avoid a break out into a faster bracket is both dangerous and inconsistent with the spirit of Sprint Bracket Road Racing (SBRR). 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
Brackets time ranges are determined by the race organizers and estimates of the typical dry track potential of the cars. Bracket times may be adjusted between race weekends but will not be adjusted during a race weekend. Cars will not be reclassified based on rain. All cars face the same conditions. Rain may favor one car over another, just as dry conditions may favor a different car. This will always be a part of multi-class racing. The focus of SBRR is on car-to-car completion and not on ensuring all brackets are occupied.
