3. Cancelation Policy:
If you pre-registered and it turns out you will not be able to attend the event, you can cancel your registration before pre-registration closes through the website.

If you pre-registered, did not cancel before pre-registration closed, and do not attend the event there are two posible outcomes.
1. Someone shows up as a walk up, and takes your spot at the event. This person will pay for their event and you will pay nothing. The way this will work is the first person pre-registered will be the first person removed from the pre-registraiton list.
2. If you pre-registered and there are no walk ups to take your spot in the event, you will pay for your spot in the event. This is because you may have discouraged someone who would have happily attended the event from showing up because there where no spots open, costing this person a fun day of autocross with WCMC, and costing WCMC an entry fee.

4. Guest Policy:
Non-members may participate in any WCMC AutoX event.
Non-member entry fees are listed above.
Interested in becoming a WCMC member? Open the "About Us" menu above and select "Join WCMC" for more information ...and yes non-miata owners can join the WCMC.
Guests (Non WCMC Members) may do as many or few events as desired. They do not need to join WCMC to continue AutoXing with the club.

6. FRS Radios:
Radios will be provided for course workers, but if you would like to bring your own radio you are welcome to. We use Motorola FRS Radios and are usually on a sub channel to try to eliminate local chatter. We will announce the channel we are going to use in the Drivers Meeting, but it is usually channel 7.1

7. Season Points:
Points will be posted with results for each event. See below to see how points are awarded.

Back to top

8. How Points Are Awarded:

Classes NA, NB, NC, and ND
No season championship is awarded for these classes. Novices may begin autocrossing at any time of the year. However, times recorded in class A are scored towards the appropriate class for season championship. This means a driver can start the season in any of these classes, move up to their appropriate class mid-season, and still be in competition for the points championship if they run a full season. And how many events are in a full season you may ask, click here to find out.
Classes A, B, C, and D
Season points are earned relative to the Stock Fast Time of the Day (SFTD). Each competitor will earn season points based on: Points = 1000 * (SFTD) / (best run).
Class F
Season points are earned relative to the Fastest Miata of Class F (FMCF): Points = 1000 * (FMCF) / (best run).
Classes R, S, T, U, V1, V2, V3, and W
Season points are earned relative to the Miata Fast Time of Day (MFTD). Should a Non-Miata (Class R, S, T, U, V1, V2, V3, or W) get fast time of the day (FTD)...they will receive 1000+ points. Points = 1000 * (MFTD) / (best run). If there is a Hot Hatch (HH), PonyCar (PC), V1, V2, V3 or any other temporary class, they will earn Season Points in the class they should have been in if this class was not created for the event.
Changing to Class F Midseason

Drivers who run part of the season on street tires or without forced induction in classes A thru D, and then move to class F, can elect to earn season points in class F by having their street tire times indexed by the FMCF.

To help in maintaining Season Points, points will only be recorded for club members. If you are not a club member you will not have Season Points recorded and will not be eligible to win the Points Championship at the end of the year.

9. Shared Cars:
Only one at a time! But yes, each person can enter and get a complete set of runs. Be sure to tell the registration worker that you are co-driving a car. Drivers who share one car will not be allowed to run in the same run group. They will be required to run in separate run groups to eliminate the delay of switching drivers on the grid. If two drivers drive the same car they will be required to pay two entry fees. One driver can not drive in the morning and second driver drive in the afternoon for a single entry fee.

10. Spectators:
Are welcome and may attend for free. For insurance purposes, they must sign a liability waiver. Spectators are not allowed in the grid, but can watch from the designated parking and spectator areas. For minors (under 18) please see Topic #10 on this page for more information.

11. Under 18:
Drivers and Spectators under 18 must have both parents/guardians sign our waiver for insurance reasons.

Waiver (Minor)

Waiver(Parental Consent)

12. Car Classes:

Novice (those who are new to autoxing)
We offer to match each first-time driver with a more experienced "buddy" who can ride along during the morning runs.
Drivers may only remain in these classes for their first 5 events. And if they win this class twice, they will be moved up to their appropriate class. ("Win" means an event win over at least 2 other class entrants in their class.)
Their points will carry over to their appropriate class points for the year when they move out of this class.
'90 - '97 Miata
'99 - '05 Miata
'06 - '15 Miata
'16+ Miata
Miatas with superchargers, turbochargers, Engine Swaps, Race Tires, or other excessive performance modifications.
Race prepared cars that don't fit anywhere else or Race tires on a Non-Miata.
Hondas; S2000, Civics, etc. (There must be 5 cars that fit this class for the class to be created.) Race Tires will bump you to Class R

Non-Miata under 2.5 liter
Some cars will be to move to U for various reasons. Some of these are:
Rotary engines [Rotary displacement does NOT equate to reciprocal displacement]
Forced induction
AWD (Will be moved to Class W if 5+ cars or Class U if less than 5 cars available)
S2000's (If there are enough Hondas they may elect to move to class S)
Excessive mods
Race Tires will bump you to Class R

UF Non-Miata over 2.5 liter Front Wheel Drive. Anything goes other than full race prepared cars. Race Tires will bump you to Class R.
Non-Miata over 2.5 liter Rear Wheel Drive. Anything goes other than full race prepared cars. Race Tires will bump you to Class R.
V1, V2, V3, HH, PC
Visiting club or similar cars so they can all remain in the same group
W "Rally" cars: WRX, STi, Evo, etc. (There must be 5 cars that fit this class for the class to be created.) Race Tires will bump you to Class R

What if I have a truck, SUV, or cross over SUV? We do not allow these vehilces to autocross unless they are highly modified. By that we mean it is lowered, stiffer suspension, stiffer roll bars, performance tires. It must be prepared for autocross, as in not stock and not a roll over risk.

Here is a copy of SCCA's Rollover Potential Guidelines

Unstable vehicles with a high center of gravity and a narrow track, that do not meet the rollover guidelines below such as SUVs, minivans, and pick- ups, must be excluded. Extra caution should be exercised with non-traditional vehicles (e.g., trucks using racing slicks).

The SCCA Safety Committee has reviewed the allowance of competing cars with higher roll centers and has prepared the following chart to be used as a guideline for assisting Regional members in determining whether a vehicle has a higher than average potential to roll over in Solo® competition. Vehicles falling into the acceptance range still have the possibility to roll over but they are less likely to roll over than those that are not in the acceptable range are. Refere to the chart below.

Roll Over Graph

The measurements are to be taken from the ground to the tallest point of the vehicle for the Overall Vehicle Height and the normal track measurement for the Average Track Width. (See figure below.)

The Autocross Coordinators may use a Static Stability Factor (SSF) for classing new vehicles. SSF is defined as 1⁄2 track width (T) divided by the height of the center of gravity above the road (H) and can be calculated by the formula SSF=T/2H. Vehicles with an SSF of less than 1.30 should not be permitted to compete in Solo® events due to the higher risk of rollover.

16. Sound Limits & Measurement Procedures at WCMC Events

To eliminate complaints from the surrounding community this year we are enforcing a sound limit on cars. The maximum limit will be 100 dBA.

The measurement will be taken at a point where the vehicle can reasonably be expected to be under load at full throttle. The measuring point will be 50 feet from the edge of the course using an ANSI Type 2 sound meter set to “A” weighting, “Slow” response. The microphone will be 3 to 4 feet above ground level, positioned perpendicular to vehicle direction of travel. The microphone will be away from structures (e.g., buildings) as is practical.
If a vehicle exceeds 97 dBA, the Autocross Coordinators will notify the driver of any measurement over 97 dBA.

If a vehicle exceeds 100dBA, the driver will be allowed an attempt to reduce the sound level of the vehicle before his/her next run that day. If a viable remedy has been attempted in the judgment of the Autocross Coordinators, the driver will be allowed a “second chance” for the next run. If the driver declines any “repair action” or the “repair” is deemed inadequate by the Autocross Coordinators, the driver will forfeit all subsequent runs in the vehicle (unless an adequate “repair action” is completed before the next run). If the vehicle exceeds 100 dBA again on the “second chance” run, the driver will be allowed another attempt as before to reduce the sound level. The Autocross Coordinators may approve a final “third chance” run after another remedy to reduce the sound level. If the limit is exceeded on the “third chance” run, the run will be scored a DNF.

Any “repair actions” to reduce the sound level of a vehicle may not be removed (including the next day of the event) and may be subject to reinspection by the Autocross Coordinators. If the “repair” has deteriorated after passing the sound level requirements at the measuring point, it must be addressed again. The Autocross Coordinators have the right to disallow a repeat of the “repair action” that deteriorated. The “repair action” may be changed or modified to improve the quality of the “repair” and/or further reduce the vehicle sound level. Drivers that receive a DNF for non-compliant sound limits must make further “repair actions” to reduce the sound level to compliant readings before starting runs at the next event.

These general sound limit regulations WILL NOT override specific local area sound limit requirements, regulations, and/or penalties.
