Drenth Gearboxes presents the high-performance Subaru STI gearkit, a comprehensive dog engaged straight-cut 5-speed gearset featuring a homologated FIA Group N ratio set.
Specifically designed for N10, N11, N12, and N14 models, this gearkit offers unparalleled performance on the track. While fitting into the OEM gearbox housings requires a minor casing modification, the end result is a seamless integration that enhances your Subaru's racing capabilities.
For even greater control and traction, customers have the option to replace the OEM front differential with a Drenth Gearboxes Limited Slip Differential.
