Shift like a pro with the SADEV 6-Speed sequential gearbox for your Global MX-5 Cup car or Ultimate MX-5 track car. The addition of a SADEV sequential gearbox brings your driving experience to a new level with no-lift upshifts and auto-blip, rev-matched downshifts. The addition of this gearbox will take the focus off of shifting and place it on your race craft.

The SADev unit was selected for its elegance in engineering, reliability, speed and usability. Mazda pro racers Chad McCumbee and Tom Long developed the gearbox, and regularly set lap times two seconds faster than those with the conventional gearbox. McCumbee noted that, “The SADev transmission was a complete blast to drive. I appreciate LRR allowing me to assist in the development process. The gearbox added speed & excitement to an already amazing platform!”

Long echoed the feeling, “The SADev sequential gearbox integrates beautifully into the Global MX-5 Cup car package. The thrill of no-lift shifting mated to quick precise gear changes takes the driving experience to the next level. A must for any driver looking to add that next step component to their GMX-5 racecar.”
