It also mates with TA-01 and TA-02 variants, offering a dependable option for anyone servicing their on-road racer. This component helps restore original drivetrain geometry and keeps the car consistent lap after lap.

Why Use This Rear Gear Case

Compatibility: Specifically shaped for FF-01 applications and compatible with TA-01 and TA-02 layouts.
Durability: Designed to withstand normal road and club track stresses to help reduce failures.
Functionality: Helps maintain correct gear alignment and drivetrain reliability.

Can I reuse existing gears when fitting this case?

Yes, you can transfer your existing pinion and spur, but inspect them for wear and set the mesh carefully when reinstalling in the new case.

Is any trimming required for a straightforward swap?

Most swaps are plug-and-play but always verify screw lengths and diff placement. Some builds may need minor adjustments depending on previous modifications.

Will this upgrade improve lap times?

Replacing a worn gear case restores drivetrain consistency which can help with predictable handling, though lap time gains depend on setup and driver skill.

How often should I inspect the rear gear case?

Check the case and internal gears during routine service intervals or after heavy impacts to catch wear early and avoid drivetrain damage.
