Driven Racing STF

Driven Racing STF is purpose-built for drivers who demand crisp, consistent shifts even when pushing their car to the limit on track. This synthetic synchromesh fluid works harder than standard transmission oil by actively reducing friction and heat while protecting gears, bearings, and synchronizers under extreme conditions. The advanced formula features corrosion inhibitors and a shear-stable viscosity index improver that keeps your shifts snappy lap after lap without breaking down, while staying compatible with the yellow metals found in modern manual transaxles.

Whether you're running a manual transmission that calls for ATF, need multi-viscosity performance, or are prepping a 2-cycle gearbox, STF delivers the thermal protection and synchronizer engagement your build demands. If you're serious about keeping your manual transmission bulletproof through track sessions and spirited driving, this is the fluid that belongs in your car.
