An organization designed to promote radio controlled s/k racing through guidelines. Spec racing is designed to be fun and inexpensive; it is our goal to encourage that by establishing a universal class of s/k race cars. We have made a concession to allow for a higher end of racing in the 19 turn class.

 

General rules:

1. Cars must weigh a minimum of 2.30lb., race ready with transponder.

2. Maximum width front and rear may not exceed 8.25”. This will be measured from the outside widest point of the wheels, or tires.

3. Wheel base must be between 9.5” and 10.5”, measured from the center of the front axle to the center of the rear axle.

4. The chassis must remain under the body, from the firewall to the rear bumper.

5. A spoiler may be added to the rear of the body. It must be no larger than 1.5” high and 4” wide. The spoiler must be centered with the body.

6. Front bumpers may not extend more than 1 1/2" forward of the body, and may not be wider than 3”. Bumpers must be centered with the chassis.

7. Rear bumpers and nerf-wings must remain under the body. They must also be smooth and secure.

8. All tires and wheels must be 1/10 scale only.

9. “Spec center dampeners” must be used. This means rod with tubing.

10. A “center shock” or “side shock” may not be added to any car.

11. No more than one dampening tube may be used on any one car, and must be used to dampen side to side only.

12. Qualifying heats will be 4 minutes and main events will be at the discretion of the race director.

 

 Approval process for new s/k cars, and bodies:

1. The item must be submitted for examination in a complete car form. No electronics are necessary.

2. The car will be examined by SKOR officials, and approved or denied on an individual basis.

3. It will be evaluated on many different criteria, including but not limited to the following guidelines: -Does the car represent a spec s/k race car? -Does the car have an obvious advantage over all other s/k race cars currently approved? -Is it a copy of an s/k race car already in production? -Are the components used on the car readily available, or able to be made readily available at the time of production? SKOR reserves the right to approve or deny any submitted product for any reason, and guarantees to disclose the reason to the manufacturer. SKOR will not sanction copies of bodies or cars and will not be responsible for the actions of any manufacturer doing so.
