The Miata

Classed Miata Trophy entrants must compete in either a standard MK3 MX5 Chassis Code NC (including NC2 or NC3), or standard MK4 MX5 Chassis Code ND. The original silhouette must be maintained, except the variation caused by the fitment of wire towing straps in accordance with Motorsport UK regulation Q13.1.3(b).

Cars must be presented to a high standard. Unpainted panels, unrepaired damage or cars not achieving a satisfactory level of preparation and presentation, as judged by the championship scrutineer, may receive a warning and may ultimately result in disqualification.

In addition to the control items highlighted on the image above, there are a few general requirements from Motorsport UK, the UKs governing body:


The following articles of the Motorsport UK Blue Book ‘Section K Competitors: Safety’ are highlighted as being applicable, but not to the exclusion of any other.

Safety Harnesses: In order to maintain the integrity of the harness system in the event of an accident, it is recommended that these should be a minimum of five-point attachment, in accordance with Q 13.10.2. 

Seats: It is strongly recommended that seats have side wings or side head restraints to take into account lateral forces.


Advertising on vehicles is subject to requirements set out in Motorsport UK Yearbook Q 19.2.2 and H 28 & H 29 in particular. For the avoidance of doubt, use of the side windows for advertising is strictly prohibited.

An Miata Trophy championship sticker set will be distributed in advance of the first round of each season. This will include, but is not limited to stickers in the following positions:

  • Windscreen top
  • Front and Rear number plates
  • Number Board

Black race numbers on a white number board must be located on both driver and passenger door – the number on the bonnet may be substituted for reflective yellow number on the windscreen on the passenger side under the screen top (as required by Section Q 11.4 of the Motorsport UK Yearbook). An additional car number should be run on the rear profile of the vehicle.
