Product information "Coolerworx Shifter X-Clutch Kit"
Xtreme Clutch Stage 2 & Coolerworx Shifter
Our Coolerworx Shifter X-Clutch Kit provides the basis for your MX-5 to shift reliably and precisely in order to get the most out of every moment on the racetrack.
Xtreme Clutch Stage 2: This clutch impresses with its maximum power transmission and extreme resilience, which enables seamless and efficient power transmission even under the toughest conditions.
Coolerworx Shortshifter Thermoplastic: With precise and short shifting distances, every shift is an experience. The Coolerworx Shortshifter ensures a direct and responsive shifting feel, which is essential for fast lap times. Thanks to the thermo-neutral shift knob, it does not heat up when exposed to constant noise on the race track.
The interaction of these components guarantees an outstanding driving experience in which the shifting feel and control of the clutch mesh harmoniously for an incomparable racetrack experience.
We can install the kit for you and register all necessary parts with the TÜV.

Installation & TÜV
This performance package was developed by SPS
Motorsport on the racetrack, adapted for street use, and continuously refined.
All components are engineered in-house and used in our own race cars —
delivering maximum performance, uncompromising quality, and a clean, OEM-like
engine bay appearance.
Two Options – Parts Package or Full Installation
You can choose between two configurations:
Parts Package (without installation): Receive all components for self-installation.
ECU tuning, dyno protocol, and TÜV registration are not included.
Full Installation (with tuning &
registration): All components
are professionally installed at SPS Motorsport. The ECU is then
individually calibrated on our in-house dyno and on the road — including a
dyno protocol. Finally, the entire conversion is inspected and officially
registered at our facility. Registration is included in the price.
Power Upgrade to 230 HP
In Stage 1, we install our SPS turbo kit for the MX-5
NC along with a high-flow sports catalytic converter. To manage thermal load,
we add an upgraded water radiator and our oil cooler kit. For reliable power
delivery, a reinforced clutch is installed. The package also includes a full
oil change to Motalin 10W-60 HP Racing with a new filter.
Note: Full power output is only achieved when paired with
an exhaust system featuring a minimum pipe diameter of 55 mm. We recommend our
Group A exhaust system, which can be added as an accessory during checkout.
Without it, the 230 HP target will not be reached.
Registration Notice
⚠️ This performance package can be combined with these exhaust systems:Friedrich Motorsport Group AFox/SPS Group AFor other exhaust systems please contact us in advance via email, so we can check first whether a TÜV registration is possible.
Upgradeable & Modular
Our packages are modular and future-proof. If you
decide to upgrade later, we’ll provide the necessary support and guidance to
expand your setup.
Lifetime Support
Every performance package installed by us comes with
lifetime support. Since we use these products ourselves — on the road and on
track — we can help with nearly any issue. Got questions? Just ask!

Roadster Challenge Club NA
All classes are regulated by power-to-weight ratio, individually defined
for all generations: NA, NB, NBFL, NC, ND, and the 124 Spider. In the smallest
class, NA, NB, and NBFL models run at approximately 200 hp, while NC, ND, and
124 Spider models are limited to around 190 hp. This class is aimed at vehicles
that retain the original MX‑5 character, with modest performance upgrades and a
focus on near‑OEM design.
Roadster Challenge Club 2WD
This class allows vehicles with approximately 250 hp (NA/NB/NBFL) and 230
hp (NC/ND/124 Spider). Cars may run naturally aspirated engines, turbochargers,
or superchargers — as in all classes. More modifications are permitted compared
to Club NA, but the drivetrain must remain rear‑wheel drive.
Roadster Challenge Pro
The second‑highest performance class, also regulated by power-to-weight
ratio. NA/NB/NBFL models may run up to 330 hp, while NC/ND/124 Spider models
are limited to around 310 hp. Forced induction (turbo or supercharger) is
permitted.
Roadster Challenge Extreme
