BRSCC MX-5 SuperCup Technical Specification


MX-5 SuperCup Race Car Specification

The Mk3 (NC) model of the popular Mazda MX-5 sports car makes a fantastic base for the Mazda MX-5 SuperCup Championship.

The Sport version of the Mk3 MX-5 features a 2.0 naturally aspirated engine revving to 7500RPM and producing over 180BHP in  MX-5 SuperCup specification. This is linked to a close ratio 6-speed gearbox and a limited slip differential to put that power onto the track.

Combined with the famous MX-5 front engine/rear drive layout, near perfect weight distribution and Mazda reliability, all the ingredients for a great race car are there.



There are several main modifications to the standard car that are permitted by the regulations in order to improve performance and create a level playing field for racing.


A control Sanspeed championship ECU re-map for all cars adjusts the engines air/fuel ratio across the rev range to produce an increase in power and torque, while a Pipercross induction system is also fitted to improve the engines breathing. The identical map and intake on all cars ensures that performance is kept truly equal.


The cars all use the control 4-to-1 exhaust manifold suppled by Racing Beat Europe,  which provides noticeably increased power and better noise compared to the standard system. From the manifold back the exhuast is 'free', but must remain a twin outlet system exiting in the standard positions. 


Adjustable GAZ Gold dampers and a free choice of spring rates replace the standard road suspension, improving the handling for racing while also offering the competitor more set-up options. The anti-roll bars are also upgraded to stiffer Eibach components that are adjustable front and rear.


The Avon ZZR is the control tyre for the championship, giving the ultimate in dry weather performance from a road legal race tyre. The regulations limit competitors to using a maximum of 16 tyres for all the championship rounds in the season.


ABS and Stability Control must be disabled on all cars. Standard discs and calipers are used but brake pad material is ‘free’. An optional brake balance adjuster may be fitted to alter the front/rear brake bias, also giving the driver more choice on vehicle set-up for different track conditions.

Weight Reduction

A minimum post-race vehicle weight (Including driver) of 1110kg is specified for the SuperCup Championship, easily achievable through removal of the MX-5s folding roof (mandatory) and other unnecessary interior items.


A specifically designed Safety Devices  6 point bolt-in roll cage provides superb driver protection while also stiffening the standard MX-5 Shell. This alongside other mandatory safety equipment (Race Seat, Harness and Fire Extinguisher) ensures the driver is well protected should an accident happen.

Full details of permitted modifications can be found in the championships technical regulations.
