The original IB6 type gearbox has a final drive ratio which is designed primarily for economy not performance. By increasing the ratio from the original 3.8:1 to this 4.3:1 version you are effectively taking top speed away from sixth gear and adding acceleration.

Motorsport transmission specialists world wide have been using this trick for many years to great affect. The higher the final drive ratio the faster the acceleration through the gears to the terminal speed.

With a ratio difference of approx 12-13% that effectively means a lower top speed of 13%. At 7000 RPM in 6th gear with this final drive kit equates to around 155mph which is a little more realistic and gives the full use of the gearbox.

With a shorter ratio and full traction there will be a direct increase in acceleration through every gear.
