What type of race harness should I use? Are 2 inch better than 3 inch?
We recommend any FIA approved or SFI certified race harness for use with HANS Devices. Some manufacturers are marketing special 2 inch shoulder straps for use with the HANS Device but these are not required. HANS only tests with SFI certified 3 inch harnesses. Additionally, based upon better stretch and aging characteristics, we prefer that drivers use polyester belts. However, both nylon and polyester work fine with HANS Devices.
