A Caterham or Westfield cars performance can be completley transformed By fitting a close ratio Ford Type 9 Gearbox.The main benifits are a longer more useable 1st gear ratio. This allows the car to stay within the power band of the engine utilising all of the torque. We offer several ratio sets in either helical of Semi helical kits depending on your intended use.
For cars fitted with the Ford sigma engines we can offer a custom made one piece input shaft a common week point as original factory supplied boxes had a welded hybrid input shaft which often fractures ! causing loss of drive.
This option is available on both our Semi Helical boxes and FM275 sports touring Boxes This allows you to upgrade your ratios without the hassle of changing clutch set up !
Transmissions and drive trains are often overlooked when improving performance, the truth is without the right gear ratios you will not gain the true performance of any engine tuning !
