RMSolo 2017 Supplemental Rules

(Updated February 10, 2017)

These rules supplement the 2017 SCCA National Solo Rules. They will take precedence over optional sections of the National rules where conflicts exist. Mandatory sections of the National rules, as defined in Section 1 of the 2017 SCCA Solo Rulebook, will be enforced.

Pre-Registration and On-Site Event Check-In Hours

Pre-registration and pre-payment is required for all events. Potential entrants arriving without first having pre-registered will be allowed to run only with the approval of the event chairperson. The pre-registration times and dates will be posted on the RMSolo website and announced on the RMSolo email list.

Any potential entrant arriving after on-site event check-in has closed will not be permitted to run. Exceptions must be approved by the event chairperson. The check-in hours will be clearly posted on the event announcement.

Behavior at the Event

Drivers must drive in a safe and controlled manner at all times while on the event site.
Posted speed limits on the event site must not be exceeded.

Speeds in the grid and pit area must remain at a walking pace, and any extreme driving maneuvers such as tire spinning or "skid pad loops" intended to heat tires before reaching the starting line of the course are expressly prohibited, and may result in forfeiture of a run, or in extreme circumstances, expulsion from the event.

Furthermore, any extreme driving displays or unsafe driving behavior in the general area surrounding the event site including public streets are expressly prohibited, and may result in disqualification at the discretion of event officials.

No Smoking Areas

There will be NO smoking or open flames allowed in grid or any other area where fueling may occur. Other areas may be designated no smoking at the discretion of event officials.

Vehicles Allowed in Grid and On Site

There are to be no wheeled vehicles, motorized or not, allowed in any grid area other than competitors' cars or golf carts. The grid area is defined when grid is set up and ready for vehicles to enter and exit, until the course is closed at the end of the event, as determined by the Event Chair. Bicycles or any other vehicles allowed for use on the site, must be walked completely through grid. The Youth Stewards will be exempt from this stipulation for the purpose of escorting Junior Karts from grid to staging and back to grid as long as all vehicles have been stopped in grid by the Solo Safety Stewards.

The Chief of Safety may also restrict wheeled vehicles from additional areas as deemed necessary to promote safety at an event. Also, if a vehicle is required for a medical reason, its allowable use will be determined by the Chief of Safety.

At PPIR, the grandstand side of the grid areas will be allowed for use by cars and motorcycles for the ingress and egress from the site only. This does not allow for movement from paddock area to paddock area. Any question regarding this will be determined by the Chief of Safety.

Skateboards (motorized or manual, with or without handlebars or seats) roller blades, roller skates/wheeled footwear (motorized or manual) are prohibited from use in all areas of the event site. If there are any questions about the valid use of any vehicles, the Chief of Safety will make the final determination.

Timing Head Damage

Any entrant that damages the start or finish timing heads will be required to pay for the replacement of the damaged head. Approximate costs will be $125 per timing head.


Riders are allowed in competing vehicles. The riders must be at least 12 years old. The riders must also be wearing an approved, properly fitting helmet and seatbelt. All parts of the rider's body must remain inside the car while on course. The purpose of this allowance is to accelerate the learning process. Minor (under 18) riders must have a properly executed (signed by BOTH parents) Minor Waiver on file.

This allowance does not permit a competitor to miss or be late for their work assignment, nor does it allow for undue delays of the event. Failure to report on time for a work assignment or failing to complete a work assignment will result in all runs for that event being DNF'ed. Should a competitor take a ride during their run heat that results in failure to be ready to compete, that run shall be forfeited.

Number of Drivers Per Car Per Heat

The number of drivers per car in any heat will normally be limited to two at any single event. Three drivers per car may be allowed, upon approval by the Event Chair. Approval must be obtained by direct communication with the event chair, prior to registration for the event.

Approval to run three drivers per car does not guarantee all drivers will receive all prescribed runs. The Grid Captain has the authority to cause a driver's run to be forfeited, if allowing that driver's run would unduly delay the event. It is the driver's responsibility to effect driver changeovers quickly and efficiently so as not to cause an undue delay. The five-minute delay between runs rule will remain in effect.

Sound Controlled Events

When site restrictions dictate, sound limits will be enforced. Click here for sound control policy/procedures.

Considerations for Course Designers

Supplemental rules regarding course design for World Arena are available here.

Annual Championship Series

Series Qualifying

The championship series will consist of approximately 10 Points Events. Greater than half the series' points events must be run in the same class to qualify for series standings, for example at least 6 events in a 10 event series.

To qualify for the series, a driver must score points in the same class at the required number of events. Qualified drivers are marked with a “Q” on series standings web pages.

The 2017 Tire Rack Championship Tour counts as a Points Event

A driver's series points are the sum of the driver's highest scores from the required number of events.
Championship Series year-end awards will be given out to all SCCA members who qualify by completing the prescribed minimum number of events. To receive a year-end award, the entrant must be an SCCA member. An entrant may become an SCCA member before the last event of the series to be eligible for a year-end award, in which case points will be awarded retroactively.

At the end of the Series, non-SCCA member results will be removed from the standings and members place standings will move up to fill the gaps.

Championship series points ties are broken by adding the points from the drivers’ next highest scoring events until the tie is broken.

Overall Points Trophies will be awarded to the top 20 qualifiers.
Series End Class Trophies will be awarded to all national and regional classes as follows:
X Class will award top 3 series qualifiers.

Novice Class will award top 10 series qualifiers.

All other classes will award the top 3 series qualifiers, and if there are 10 or more series qualifiers additional positions will be awarded.  For these larger classes, trophy count is determined by dividing the number qualified by 3 and rounding up. For example: 19 qualified; 19 divided by 3 = 6.3; rounds up to 7 trophies.

The above series trophies and other year-end awards are presented at the Championship Series Awards Banquet.

Points Event Score

The fastest single run for each competitor will determine the finishing position.

For Points each driver's fastest run will be scored relative to the event's fastest indexed time.

With this formula: Event Points = 1000 * (fastest indexed time) / (your fastest indexed time)
Where: indexed time = (actual time) * (class RTP index)

For 2017, RMSolo is using the "Racers Theoretical Performance" PAX/RTP index.

Women's and Novice classes will use open class index of each car.

A list of official indexes for all classes will be available at the events or by mail if necessary.

Driver Event Points are normally available after the Event Trophies are given.

Points Event Trophies

Consistent with national solo events, the number of trophy positions in each class is determined by the number of drivers in the class:

Qualified Entrants
(Entrants that have participated in the minimum number of events to qualify for a trophy)
Number of Trophies
1-3 1
4-6 2
7-9 3
10-12 4
13-15 5
16-18 6
19-21 7
22-24 8
25-27 9
28-30 10

X class awards 3 trophies, regardless of entries.

Points Event Trophies will be awarded in each class after event competition and score audit are complete.

Score sheets will show a “T” next to drivers in trophy positions. Preliminary standings are not posted for Novice class; Novice results are released with final results.

Event awards will be forfeited if not picked up on the day of the event. Additional awards may be given out at the discretion of the event chairperson. RMSolo awards will not be given out at non-points practice events, nor at locally-hosted national events.

Regional Classes

RMSolo will use all of the nationally recognized Solo classes, with the exception of the "L" classes (see "Women's Class",) plus the following local classes:

Novice class

In addition to the standard SCCA classes, a Novice class will be available. The intent of the novice class is to provide an additional incentive and reward for "novice" drivers. Novice class is open to any beginning driver who has competed for less than a full series. A competitor that scored enough events to qualify in a prior RMSolo Championship Series is not eligible for Novice class.   A competitor can opt-out of novice class at any time.

Novice status must be requested during registration for each event.

Instead of competing only in Novice class, all Novice drivers will drive with and compete in their respective open class, and will be eligible for awards in those open classes. The novice class is indexed using the current indexes.

At the end of each event, a separate list of novice drivers will be created, sorted by index times, and novice trophies will be awarded from this list. This means that a novice driver could conceivably receive trophies in both novice and open class.

If a Novice class competitor scores 940 points or more at three Series Points Events, the driver will no longer be eligible for Novice status, but will still be eligible for the year-end "Rookie of the Year" award.

X Class

In addition to the standard SCCA classes, an X-class will be available. The intent of the X-class is to provide competition for "more experienced" drivers by allowing them to compete in one indexed class. The X class is open to any competitor.

Only the first 3 valid runs will be scored for X Class. All subsequent runs will be scored as a DNF, but times will be recorded.
Cars competing in X class should have ONLY their car number and index class designation (X) on each side of the car, not their open class designation.

A competitor can move to X class at any time during the series, and their series points will be moved to X class. However, no points earned while driving in X class may be moved out of X class.

Women's Class

RMSolo provides a single indexed Women's class.

Women have the option of running in the indexed Women's class (W class), or running in open class, but not both.

Cars competing in the Women's class should have ONLY their car number and index class designation (W) on each side of the car, not their open class designation.

Open Street Prepared

In addition to the standard SCCA classes, an Open Street Prepared class will be available. This class encourages maximum creativity for cars that do not fit in the SCCA's other categories.

OSP vehicles must use DOT approved tires and be "street legal." RMSolo will make no effort to verify legality in terms of Colorado laws; however, an OSP car must be something that could conceivably be registered and driven on public roads. For example, it must have a windshield (if originally equipped with one), DOT legal headlights, taillights, windshield wipers (where applicable) and a reasonable exhaust. OSP is indexed at 0.880.

Formula Junior Karts

Formula Jr. Karts will follow the rules for FJr. kart classes as printed in the SCCA Solo Rule book, and amended in the FasTrack section of Sports Car magazine.

FJr. classes are eligible for Series Awards. Awards will be distributed following the guidelines found elsewhere in these Supplemental Rules.

Points will be scored using the same methodology described elsewhere in these Supplemental Rules.

Class Bumping

There is no minimum number of entrants required per class.  Class bumping will not occur in classes that have only one entrant.

Changes to Supplemental Rules

Supplemental Rules will be approved by the active Chiefs Team, and published by the Solo Chair(s) prior to the first points event of the Championship Series. “mid-season” rules changes may be made to resolve a safety issue, or if deemed to be for the good of the sport.  Changes to the supplemental rules will be voted on (in person or electronically) by the Chiefs Team. A simple majority of those voting will determine the acceptance of any change.
