Why the 7-Speed Sequential Gearbox Has Become the Modern Motorsport Standard
The modern 7-speed sequential gearbox has transformed the way race cars deliver performance. The difference over a standard H pattern syn 7-speed sequential gearbox chro gearbox on the race track is on average around 1.5 -2.0 seconds quicker per kilometer.
Specifically:
• reduce time lost during gear changes
• improve acceleration
• choice of ratios
• greater confidence on the race track
• focus more on driving and less on shifting
These advantages explain why sequential gearboxes have become the preferred choice in rally, circuit racing, hill climb, endurance racing and time attack competition.
