Gear-X Final Drive units for the S2000 engine meet or exceed OEM specifications and are fully tested in house, both in our workshop and out on the track before being released for general sale. We've been evaluating these final drive kits in various S2000 differentials and engine configurations for most of 2009 and are ready to offer them to our customers. With our feedback, Gear-X has been able to offer a few ratios that are very well suitable for street/track, roadrace, autocross and forced induction.
The most popular ratio is the 4.44 and 4.57 which are used extensively in todays street cars, weekend racers and all out racecars. The lower 3.09 final drive is reserved for forced induction/dragrace turbo. Choose your weapon!
