Good morning,

The belts on my car are a few years out of date so I will have to update them before the season starts. I read a few forum articles here on FIA vs SFI 16.1 rated belts and the FIA belts seem like the better deal with the 5 year rating vs the SFI 16.1 2 year approval.

My question is what happens when a belt has both ratings? There are two "economy" 6 point camlock harnesses available: G-force and Schroth. The G-force belt only list FIA approved. The Schroth belt lists both SFI and FIA tags are on the belts. If the belt has a FIA rating and a SFI rating which one is used for "good till" date.

For reference these are the belts off of Saferacer:

Here is Schroth's page on the Clubman harness listing both FIA and SFI tags are attached under the homologation drop down:

G-force has separate part numbers for the FIA and SFI approved belts.

For some additional info I will be using a DefNder HNR which lists it is compatible with both 2" and 3" shoulder belts. Trying it on with the current 3" Simpson belts in the car the belts seem to fit fine.

Any advice on purchasing a harness would also be appreciated.

Thank you!
