Vehicle Classes 2025

The intent of our class structure is to provide a logical progression in terms of technical development from a standard road-going MX-5 through various levels of modification up to a dedicated MX-5 race car. The full progression is available for all MX-5 models.

These 2025 technical rules are carried over from 2024 with some significant changes. A summary of the changes can be found at end of the 2025 Technical Rules document.

All entrants to club track days are required to submit a 2025 Vehicle Declaration Form. Subsequently, the form must also be recompleted when entering with a new car, or after performing any modification that may affect the class of their car.

The 2025 technical rules have three parts:

  1. 2025 Technical Rules - technical definition of modifications permitted in the various Classes of vehicle.
  2. 2025 Class Benchmarks - methods of calculating the benchmark times and the scoring system used to calculate points for each event.
  3. 2025 Benchmark Times - benchmark times for each category of vehicle.

As our club track days now operate under the CSCA rounds, Club members are also eligible to compete for the 2025 CSCA Championship. The CSCA class rules are defined here.

Club members wishing to compete in the 2025 NSW Supersprint Championship should be very familiar with the rules for that championship, which can be found on the NSW Supersprint website. In addition, members competing in the new MX-5 Club Modified Class should read the Type RM rules in the 2024 NSW Supersprint Championship rules since the MX-5 Club Modified Class rules are those for Type RM (with some adjustments).
