After much consideration, we're excited to begin this project by engaging with the public for initial input.
Our gearsets have proven their reliability across various platforms, and it's time to extend this performance to the popular 6-speed Aisin gearbox.
Given the scale of this project and the significant funding required, we're offering a highly discounted price for the first 50 pre-orders. Full payment is required upfront, but if you need more time, please email us to discuss options.
This kit includes everything needed to address common issues with factory gears and forks: forks and gears, shafts, dog rings, and a heavy-duty mainshaft.
They are made to suit all MX5s with the AZ6 Gearbox. From early 90s till mid 2000s, these kits will only fit the Aisin 6 Speed casings.
The gear ratios for ultimate strength and performance are as follows:
Speedtek Auto Racing Helical Cut Gearset:
MX-5 6-Speed Ratios (also applicable to BRZ & FRS):
Reverse: 3.43
These gearsets are designed for rapid quick shifts, offering a significantly different experience from the factory Aisin AZ6 synchronized transmission.
This kit ensures your transmission can reliably withstand upto 600 BHP (measured at power to the transmission). Additionally, we have developed a race spec lockout shifter which features a unique design to stop accidental shifting into first gear going from second to third.
We estimate these kits will be completed by mid 2025.
*Strictly no refunds on any Pre-Orders, please be mindful we are working at the fastest pace possible.
