WISSOTA & Sponsor Sticker/Patch Rules:

Drivers in all WISSOTA divisions are REQUIRED to display the WISSOTA decal and all sponsor decals provided by WISSOTA on their race cars. The mandatory decals to be displayed include (but are not necessarily limited to): WISSOTA, AMSOIL, Hoosier, Dart, Allstar, Sunoco or Turbo Blue, Pro Comp and Bassett.

The WISSOTA, AMSOIL and Hoosier decals MUST be placed on BOTH DOORS of each race car, in the first 10 inches of the body behind the front tires. Refer to the 2009 WISSOTA rule book, page 16, rule 3.2.2 and a downloadable diagram here for additional information. The sail panel area is an "overflow" area to be used if there is not enough room on the door for all required decals. Remember, the WISSOTA, AMSOIL and Hoosier decals must be placed on the doors as indicated; other decals can go underneath those on the door or, if necessary, on the sail panels in the overflow area.

Mandatory decals for each WISSOTA division are as follows:
Late Models: WISSOTA, AMSOIL, Hoosier, Dart, Allstar, Sunoco or Turbo Blue, Pro Comp, QA1, Dirthead, Speedway Motors
Modifieds: WISSOTA, AMSOIL, Hoosier, Dart, Allstar, Sunoco or Turbo Blue, Pro Comp, QA1, Dirthead, Bassett, Speedway Motors

Sew-on patches (WISSOTA and sponsors) must also be displayed on drivers uniforms. The same downloadable page described above in the decal rule contains the guidelines for required patches for driver uniforms.

These rules will be enforced by tech officials after each race. If your tech official determines that you are not complying with these rules, the penalty will be loss of all earnings and points for that event.
