Close Ratio Final Drive from Komo-Tec


Recommended Posts




The standard Exige S V6 gearbox ratio is basically not so bad but needs an improovement from 4. to 5. gear there is areal big speed gap of 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 gaerbox, one for gear 1-4 one for the gear 5-6. We change both to get a propper gear change.
In the attached board you could see the speed at 7200rpm in comparison between the standard gearbox, our close ratio and ultra 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.
