Hi Group, I found these 'Sema Specifications' stickers on the inside of the Keystone wheels on my 67 firebird. The stickers are about 1" x 1 1/2" and are white with black lettering. Does anyone know the purpose? Thanks.
Do a google search for SEMA and read up on them. The specs are to certify those are approved by SEMA. NHRA ans other racing organizations require certain parts meet those specs to be allowed in different classes.
Originally, SEMA did their own testing and certification of equipme. Now SFI is the testing and certification authority. The SEMA sticker is old but still valid for their specifications .
