The type of harness required depends very much on the type of vehicle, the type of motorsport and the certification required. If you are unsure please contact us and we can discuss the available options.

For FIA approval the shoulder straps must be 3 inches wide except for HANS Use Only harnesses where a 3" to 2" shoulder strap is allowed. If the HANS Use Only straps are used then a HANS device must be worn to comply with the FIA regulations.

For FIA approval the lap straps can be either 2 inches or 3 inches wide according to driver preference.

Crutch straps are 2" wide. Single Seater style Loop and D crutch straps have a 1" loop on the end of the 2" webbing to thread through the D rings.

At Willans we only use top quality military specification polyester webbing in all our harnesses. We do not use Nylon webbing which is inferior for harness applications due to its excessive stretch and its poor resistance to UV light and to water absorbtion. The reason that SFI in the USA specifies only a 2 year life for harnesses is the insistance of US manufacturers to use inferior Nylon webbing.

We make racing harnesses to FIA, SFI 16.1 and SFI 16.5 regulations as well as non competition harnesses to ECE and FMVSS standards. We also produce bespoke harnesses for a large array of applications where no certification is required including boats and light aircraft.
