These are brand new FIA approved harnesses with 2024 homologation, and are labelled accordingly.
Fully FIA Approved for track and road use. FIA approval is for 5 years from the end of the year purchased. For example, if purchased on 1st Feb they would be approved for 11 months of the current year plus a further 5 years. Road Use Approval: Reference: Individual Vehicle Approval (IVA) inspection Manual; Passenger vehicles (M1) dated May 2023. Page 228 clearly states: Note 1: A British Standard Part 1 1988 or evidence of FIA approval for a harness belt is acceptable.
Wrap around fixing on shoulder straps
A Magnum 4 point FIA, Road and Track Day harness from TRS, specifically made for Mazda MX-5 (a.k.a. Miata/Eunos), from 1989 to 2005. With shorter shoulder straps designed to wrap around a roll bar or harness bar, these harnesses are essential for use in your MX-5 if used on the road or track.
As standard they feature shoulder straps manufactured to the correct length ready to wrap around your roll bar or harness bar, and lap straps which adjust by pulling down to tighten.
They are brand new FIA approved harnesses with this year's homologation and are labelled accordingly. Innovative features such as a securing tab for intercom cables on the shoulder strap and thumb loops on lower shoulder straps were all pioneered by TRS and again are standard on these harnesses.
Please note that the TRS lightweight (140 gram) quick release buckle is of composite construction and is fixed to the left-hand lap strap on the drivers' side (UK RHD vehicles) and the right-hand lap strap on the passengers' side (UK RHD vehicles) With this configuration when the buckle is released it goes towards the centre of the car rather than the door. If you are ordering two harnesses, we will always supply one harness with a buckle attached to the left-hand lap strap and one harness with a buckle attached to the right-hand lap strap. If you are ordering a single harness, please confirm whether it is for the driver or passenger side (using the dropdown menu above) and we will supply a harness with the rotary buckle fixed to the appropriate side.
A harness bar manufactured specifically for the MX-5 can be supplied if required. Please use dropdown to order.
The key features of this harness are shown below and above is a detailed description. If you are not sure this harness is the correct one for your requirements, click HERE to view the full range of Mazda MX-5 Harnesses.
- 4 fixing points
- Road legal and FIA approved to FIA 8854/98.
- Rotary quick release buckle
- Shoulder straps are manufactured for the MX-5 to exactly the correct length to wrap around the harness bar or roll bar without excess webbing. A harness bar is available as an option, (see below).
- Please note the length of the shoulder straps is 122cm from the adjuster to the end of the strap. Once the webbing has been wrapped around this will leave a maximum length of approximately 70cm from the adjuster to the roll / harness bar.
- Lap straps have snap hook fixings. 7/16" UNF eye bolts and instructions are included. The lap strap eyebolts screw into the original mounting points on the sill and on the seat runners. If you have replaced or are thinking of replacing the seats with Cobra Monacos, or other base mounted seats that retain the original runners, then this is still the case. If you have seats fitted with side mounts a new fixing point will be required to the centre of the car, on the tunnel. Please select the harness stress plates from the dropdown to facilitate this requirement. All FIA seats will require this type of fixing.
- 75mm (3") shoulder straps
- 75mm (3") lap straps
- Securing tab for intercom cables on the shoulder strap
- Thumb loop on lower shoulder straps
- Standard colours are Red, Blue, and Black. Yellow, Green, Grey/Silver, Orange, Pink, and Miami Blue are special order (see dropdown above)
- Made in England
Shoulder Straps
- Shoulder straps are approximately 122cm from the adjuster to the end of the strap
- The adjustment range of the lower shoulder strap is between 10cm and 40cm
- The fixings at the end of the shoulder straps are not sewn on, and can easily be removed if you plan to wrap the shoulder straps around a roll bar

Exclusive offer for Carnoisseur customers! We are now giving away a free TRS keyring worth £12.95 with every order for TRS harnesses!

Made in the UK at the TRS factory, the keyring is 10cm in length, and is a great looking, practical accessory for all motorsport enthusiasts.
Select which colour TRS keyring you would like to add to your order using the dropdown menu above.
Please note that just one keyring is provided by order.
Webbing Colour
TRS Harnesses are available in 9 different webbing colours: Red, Blue, Black, Yellow, Green, Grey/Silver, Orange, Pink, and Miami Blue.
Red, Blue, and Black harnesses are the most common colours, so harnesses in those colours are usually in stock, if you need your harnesses in a hurry.
Thread Colour
As standard, TRS Harnesses are stitched using the same colour thread as the webbing, but contrasting colours are also available. There are 9 different thread colours available: Red, Blue, Black, Yellow, Green, Grey/Silver, Orange, Pink, and Miami Blue.
Adjusters
You can upgrade the harnesses to the Superlite or Ultralite versions. As standard TRS harnesses use steel anti-creep adjusters. Also available are premium aluminium alloy adjusters, which in addition to being lightweight, offer a smoother and faster adjustment. The Superlite harnesses use these lightweight aluminium adjusters on the shoulder straps, and the Ultralite harnesses use them on both the shoulder and lap straps.
They are highly recommended for vehicles being shared between multiple drivers, and in general we always recommend upgrading to the aluminium adjusters due to their premium look and feel.
Please note the main product image of the harnesses shown at the top of the page features the Ultralite aluminium adjusters.
Standard Steel Adjusters
50mm (2") steel adjusters
75mm (3") steel adjusters
Premium Aluminium Adjusters
50mm (2") aluminium adjusters
75mm (3") aluminium adjusters
Pull Down or Pull Up Lap Straps?
Lap straps can be supplied with either pull down or pull up adjusters. You can make your selection using the dropdown menu above.
We normally recommend pull down adjusters that sit approximately 12cm from the buckle. We recommend these so you have easy access to the adjuster, and they will definitely be positioned within the seat.
As standard, pull up adjusters will sit approximately 12cm from the fixing point at the end of the lap strap, making them difficult to access (they will be down by the sides of the seat), however we are happy to supply them if this is your preference. If you would like pull up adjusters that are a different distance from the fixing point, please contact us. We have supplied some customers with harnesses that have pull up lap adjusters that are 22cm from the fixing point but you would need to check to see if this would be right for your vehicle and the seat you have fitted.
Extras
MX-5 Harness Bar
TRS Shoulder Pads
TRS Webbing Cutter
FIA Approved Stress Plates
With these harnesses we offer some optional extras for your comfort and safety, which you can select using the dropdown boxes above.
MX-5 Harness Bar: The only way to securely, safely, and easily fit harnesses to an MX-5. In fact, this MX-5 specific harness is only designed to be used with a harness bar or a roll bar. The harness bar attaches to the seat belt towers and has the added benefit of acting as a brace giving increased rigidity. It fits both right and left-hand drive Mk 1 and 2 MX-5 models.
Please note that only one harness bar is needed per vehicle. If ordering a pair of harnesses, add one to the basket with a harness bar and one without.
- 45mm diameter CDS grade carbon steel
- Zinc primed
- Powder coated in satin black
A pair of TRS Shoulder Pads are available in three colours: black, red, and blue. They simply attach with velcro around the shoulder strap area of the harness, for added comfort for the wearer. They will be provided in the appropriate size for the harness you choose.
Also available is a TRS Webbing Cutter, for use in case of emergencies. This is a knife for a driver, passenger or marshal to cut through harnesses and webbing in the event of an accident, to quickly release the wearer and avoid being trapped in the car. The cutter meets the MSA Blue Book requirement which states "Belt cutter(s) must be carried on board at all times", so it's a must-have when racing.
Steel Stress Plates are available with a captive 7/16" UNF nut to create suitable mounting point for TRS Harnesses. FIA approved. 65mm x 65mm x 3mm.
