The standard Exige S V6 gearbox ratio is basically not so bad but needs an improvement from 4. to 5. gear there is a real big speed gap at 70km/h. Also the top speed of around 315km/h at 7200rpm is real long.
So we decided to change the final drive ratio in this gearbox, there are two final drives in this one gearbox, one for gear 1-4, one for the gear 5-6.
In the attached board you could see the speed at 7200rpm in comparison between the standard gearbox, our close ratio. The gearbox could also be used in Evora which are fitted with the Lotus sport ratio gearbox.
A perfect supplement to the ratio is our special limited slip differential we also offer.
The use of the close ratio can lead to more mechanical noise.
Gear ratios: all calculations are based on the rolling circumference of the standard tires
