Performance Enhancement

The original IB6 type gearbox was designed for economy, not performance. With this 4.3:1 final drive kit, you can transform your Fiesta ST into a powerhouse on the road. By increasing the final drive ratio from the original 3.8:1 to 4.3:1, you effectively take top speed away from sixth gear and add acceleration, providing a more engaging driving experience. This upgrade has been a go-to trick for motorsport transmission specialists worldwide, resulting in faster acceleration through the gears and a higher top speed of approximately 155mph at 7000 RPM in 6th gear. With a shorter ratio and full traction, you'll enjoy a direct increase in acceleration through every gear, making your Fiesta ST a true force to be reckoned with.
