I picked up a car recently that has been prepped for autocross and I would like to do some TT's with it, including Chuckwalla in March. The car is equipped with a rollbar and an aluminum Kirkey race seat. The belt on the driver side has been upgraded to a G-Force 4 point "tuner" belt (see link below). It is obviously an improvement over the 25 year old 3 point harness but is not SFI certified. The required safety equipment spreadsheet states "seatbelts, factory or better; properly installed Scroth ASM 4-point harness". The G-Force belt is better than factory so it appears to be legal but I'd like to confirm that and not leave it to chance. Thanks.
