Car numbers and class specs
 

What is the required minimum size for car numbers and class classification again? Im trying to make some magnetic numbers and I forgot the recommended size. Thanks

As per the 2013 SCCA Rulebook:



3.7 VEHICLE IDENTIFICATION



A. All vehicles must display numbers and class letters on both sides,

which must be readable by Timing & Scoring, Course, and Grid

workers at all times.



B. Only one set of numbers and class letters may be visible while the

vehicle is running.



C. Class shall be represented by the upper-case abbreviated form rath

-er than be spelled out. Ladies’ classes shall be indicated by the letter

“L” following the class letters. (Example: “BSPL” instead of “B Street

Prepared Ladies”).



D. Numbers and class letters should be positioned next to each other.

All letters and numbers must be on body panels, not on windows.

All numbers and class letters must use the same typeface and the

same color, and this color must provide adequate contrast to the

background color (see Appendix F for examples).



E. Numbers must be a minimum of 8” high with a 1.25” stroke. Class

letters must be a minimum of 4” high with a 0.75” stroke. In all cases,

the height of the class letters must be between 25% and 75% of

the height of the numbers. Stroke width must be at least 10% of the

height (see Appendix F.)



F. The “1” on two-driver cars and the “L” on Ladies class cars are sub

-ject to all of the above requirements with regard to placement, color,

size, and stroke.



G. Karts may use numbers and class letters of reduced size provided

that the following conditions are met:



1) Numbers must be displayed on the front and rear in addition to

both sides.



2) Class letters must be on both sides.



3) In no case may the numbers be smaller than 6” in height with ¾”

stroke, using a high-contrast color and background.
