THE SYSTEM MUST BE UPDATED AT TWO-YEAR INTERVALS FROM THE DATE OF MANUFACTURE, FOR ALL ENTRIES REQUIRING THE SYSTEM. (All cars that are NOT required by Class Requirements to use SFI 16.1 driver restraint system do not need belts updated.)
From the NHRA rulebook
SFI Spec 16.1 or 16.5 Y-type belts prohibited. (In cases where the class does not require an SFI 16.1 or 16.5 driver restraint system, the two-year recertification does not apply.) System must be updated at two-year intervals from date of manufacture.
From WDRA
SFI rated systems must be updated or replaced at applicable intervals. In those not required, belts may be inspected for wear or the use of OEM style torso crossing belts may be used.This message has been edited. Last edited by: TomR,
