RACING MEMO
DATE: March 31, 2010
NUMBER: RM 10-04
FROM: Club Racing Board
TO: All Participants
SUBJECT: SFI Decertification of Impact Products

SCCA is aware of the action taken by SFI against Impact Racing. We are in the process of determining what action (if any) will be needed for our drivers. We will communicate the outcome to our drivers, tech personnel and stewards via member email and website posting when the answers have been determined. Until further notice, it is business as usual and as long as your safety products have SFI certification (patch/sticker) that meets our current GCR requirements, you would be considered compliant.
