- Speed Cards: Instead of using speed logs, drivers use the speed cards that will be provided. A deck of speed cards includes 1 card for every possible speed and a card labeled "M.P.S." or Maintain Present Speed.
When using these cards to plot with, leave the previous turn's speed face up in front of you to show what speed you moved last turn. Then place a speed card representing your speed for next turn face down in front of you. If you wish to go the same speed as you did last turn, use the MPS card. When everyone is done plotting, all speed cards for the upcoming turn are revealed at the same time.
- Plot Errors: Any non-existant plot results in the car maintaining its speed from the last turn. Any plot that is impossible to achieve is replot at the closest achievable speed to the one originally plotted, assuming maximum possible use of wear and test tables.
- Order of Movement: The second tie-breaker for the order of movement for cars on the same row of the track changes from the inside of the track to the side of the track with a grey line. Generally, this will be the inside of the upcoming or just completed corner. Note that spaces in the same row share a front edge.
- What is a Corner? Obey cornering speeds and assess cornering penalties only when entering spaces with posted speeds regardless of one's intended use of a racing line through the corner. A car may accelerate from the last marked space of a corner.
- Changing Radius Corners: It is possible for a driver to go through a single corner and yet run over spaces with different speed limits in different rows. This makes for relatively more complex interpretations of the cornering rules.
The first thing to remember is that spending wear and rolling on the chance table in a corner does not "buy" a partciular speed, it "buys" +20, +40, or +60 mph more then the corner speed limit. So while the speed limit may change in the middle of the corner, a driver is still entitled to safely drive at 0, +20, +40, or +60 mph over that limit depending on how they have paid for the corner.
If the speed limit drops, the driver must either slow down accordingly or be prepared to increase their "payment" for this corner. Remember that all wear penalties for a corner are paid for the corner as a whole. So, If a driver is already running 60 mph over the speed limit and then the speed limit drops, the car MUST decelerate or hit the tire wall.
If the speed limit increases, the driver is entitled to increase their speed accordingly. However, since there is no way to increase speed in the middle of a plot this can only be taken advantage of if the driver ended their previous plot in the middle of the corner on the last space of the slower speed limit, just in front of the higher speed limit. Note that this interpretation does run counter to the original rule prohibiting acceleration once a corner has been entered.
If a car late brakes after entering a corner they may lose some or all of the advantage they may have "bought" with wear or skill earlier in the corner. For the purpose of determining how fast this car can go in the corner next turn, pretend that the car entered the corner at its new speed.
Slipstreaming: Drivers are not required to decide in advance if they will be trying to take advantage of a slipstream. If the bonus presents itself, the driver may take it. While the GM may prompt drivers, it is the driver's responsibility to ask for a slipstream. The front car must be plotted for at least 120 mph. The slipstreaming car does not have a minimum speed requirement. However, drivers may not take a slipstream bonus if either involved car began the turn at 0 mph. A car due a 2 space slip bonus may take only 1 space if desired.
A car that starts the turn on the last space of a corner may slip a car in front of it.
Cars may slipstream into and through a corner. Even if they only enter the corner because of the slip(s) they received.
When a car can legally slip 2 different cars, they may slip either as desired. When 2 cars would otherwise legally slip the same car, the first of those cars to take advantage of the slip will be the only car allowed to take that slip.
- Emergency Braking: After a car begins its move, it may voluntarily burn off excess speed by consulting the deceleration chart. If the deceleration chart was consulted in order to achieve the car's originally plotted speed, Emergency Braking is added to the original excess deceleration and any additional called-for penalty is paid.
- Rear Ending: Instead of automatically spinning a car that plots spaces it can not use, the offending car must emergency brake to a safe speed.
- Moving After A Spin: The turn after a spin, use start speed or acceleration for the next turn, whichever is lower. You are prohibited from pushing your acceleration or start speed that turn. Further, regardless of plotted speed or track position, a car moving after a spin moves last among all cars in the same row this turn. Cars that have spun on a racing line, may not gain any future advantage from that line this time through the corner.
- Forced Passing:
If a moving car (the attacker) would like to move past an occupied space the moving car may attempt a forced pass. A forced pass can only be attempted if the attacker has enough speed to end its move on an empty space. First, the attacker picks a car to pass (the defender). Then the defender decides either to block or not. A defender that is currently plotted at 0 (probably due to a spin) may not block. If the defender blocks then the passer gets a +2 modifier on the passing table and a collision may occur. After the defender declares their intention to block, the attacker may chose to apply skill chips or not and then must roll on the passing table. Cars that attempt a forced pass may not use a racing line through the space they are passing through.
If the defender blocks, then a collision may occur regardless of the success of the pass. For any 3 rolled on the dice during the pass attempt, the defender loses 1 wear. For any 4 rolled on the dice, the attacker loses 1 wear. This could result in 2 wear lost by a single car. If a car does not have the wear to pay for this damage, the car spins after losing what wear it does have left.
If the passer succeeds on the passing table, the passer can continue its move. If the passer fails, that driver must stop in the space moved through prior to the attempted forced pass and modify their speed accordingly.
If a successful pass results in another legal pass attempt,
the passer must add the blocker-based penalty from all previous passes this turn to the subsequent pass attempt.
This penalty is cumulative with any other penalties that might apply to this pass attempt.
If a passing car's failure on the passing table places the car in a row with no empty spaces,
the car is moved to the next row back, drops another 20 mph in speed, and loses 1 wear after an excursion into the gravel. This does not count toward exceeding deceleration. (This modification eliminated the need for off-track rules.)
- Engine/Brake Damage: If an acceleration or top speed test fails, that car's engine is damaged. A car that failed a top speed or acceleration test the first time will end up going 20 mph less then attempted this turn -- even though that speed would be in violation of the car's new/damaged acceleration or top speed. The car's new acceleration / top speed must be fully complied with next turn. If a car with a damaged engine fails an acceleration or top speed test (regardless of what kind of test caused the original damage) that car's engine fails completly and the car is removed from the race.
Cars removed from the race due to engine failure immediatly reduce their plotted speed by half (rounding down) and move that speed for this turn, moving off track at the end of the move. If the car crosses the finish line at the end of the race, the car stays on track at the end of this move.
If a brakes test fails, that car's brakes are damaged. However, no future wear penalties are incured. Any subsequent brakes test failure, causes the brakes to fail completly and the car is removed from the race. Cars removed from the race due to brake failure are removed from the track immediately.
- Crash Involvement: When any on-course crash occurs, mark the row it occured on and remove the crashed car immediately. Note that spaces in the same row share a front edge. Any other car that subsequently ends its move in or beyond the marked row of spaces must roll on the chance table using the following modifiers:
|move completed 0-2 spaces after crash row||-2|
|move completed 3 or more spaces after crash row||-1|
|crash row is a 3-wide section of track||-1|
Note that the last modifier can be cumulative with either of the previous two and that skill chips may be used on this die roll.
- Race Finish: A driver has finished the race when he enteres the space immediately before the start/finish line (nose across the line). Any car that crashes the turn they crossed the finish line is not considered to have finished the race. Any car that finishes the race off track or in a spin, finishes last of the cars that also finished the race this turn.
- Definition of a Row: Cars are considered to be in the same row when the front edge of their spaces line up. This is most relevant in relation to Order of Movement and Crash Involvement above.
- Green Arrows: In addition to the regular racing lines shown in red on WBC tracks, a few tracks also include green arrows. A green racing line allows the driver who uses it to go 40 mph over the marked speeds over which it runs instead of the usual 20 mph over. All other rules regarding the use of lines are the same.
