Race Numbers and Number Panels
Please be aware that SKUSA is again making specific number panel colors MANDATORY for the SuperNationals -- except for KZ. Please make sure to choose number and background colors that sufficiently contrast each other. Number panels that are clear and readable both on track and in tech are TECH items. If you would like to order custom number panels from the SKUSA-preferred vendor in the Los Angeles, CA area, please contact Alex @ Axcel Fast Graphics to place your order: 626-294-0075, Axcel Fast Graphics has worked with SKUSA to help design the layout and color schemes, so all you need to do is provide your class and PRE-APPROVED race number (with letter designator).

NOTES: (1) SKUSA does NOT make or provide number panel decals. Each driver is responsible for acquiring their own, and to spec. (2) Unless you are a National Number plate holder, the letter designator is MANDATORY, and must be ½ the height of your race number and clearly readable on all 4 sides of your kart. This is a TECH ITEM. For those of you who won't be ordering custom number panels from the preferred vendor listed above, please see the color schemes below, and ask your printer to follow these guidelines as closely as possible. (The Superkarts and ProKart logos are optional.) See Rulebook section 20.2.2 for text style and size specifics.

Contact the SKUSA office to verify your assigned race number and letter designator PRIOR to having your number panels printed. If you allow your SKUSA membership to lapse, we cannot reserve your kart # and you run the risk of someone else taking it.. SKUSA does NOT allow duplicate numbers in the same class, even with a different letter designator. The letter designator is ONLY there to identify where that driver resides..

You can only reserve a race number with SKUSA if you have an active SKUSA membership. With the exception of single digit earned numbers (see below), the only number that you are authorized to race with is the number found on your SKUSA membership card -- INCLUDING the area designator. If you race without the area designator letter, you will be exposed to the possibility of having to change your number panels at the event.

Single digit numbers

Only Regional or National SKUSA class champions from the previous competition year earn the right to run single digit numbers the following year.  Even if a driver chooses not to run the single digit number earned, that number is reserved and unusable by any other driver for the balance of the competition year.

If you are moving to another class or wish to change your reserved race number, contact the SKUSA business office to check and reserve a new number: email This e-mail address is being protected from spambots. You need JavaScript enabled to view it or call 951-491-0808.
