Weir final drive gears are CNC machined and lapped for quiet operation!
The high quality ring and pinion gear set is shot peened, a process which further strengthens the gears and adds durability.
As a result, we are proud to offer enthusiasts the best final drive gears on the market today.
What is a final drive gear set?
The final drive ratio is the final gearing between your transmission and the driven wheels. By changing it, you can affect the performance of your car.
A lower number final drive ratio will lead to less torque at the wheels but a higher top speed.
A higher number offers more torque at the wheels, closes the gear ratios, and a lower top speed.
The standard ration for a GT86 & BRZ is 4.1
By changing your final gear ratios, you can optimise the car for different applications.
eg: 1, GT86 but want more acceleration and closer gear ratios to keep the engine in the correct rev band - use a 4.30, 4.56 or 4.88.
eg: 2 GT86 automatic cars from the factory have very high gear ratios, 4th in the auto is the same ratio as 5th in the manual car. Use a 4.56 or 4.88 to improve acceleration.
eg: 3, Forest rallying requires close ratios and usually only a low top speed - use a 4.88 or 5.30.
eg: 4, cars using a gearbox conversion where a lower ratio is required - use a 3.58.
Note: You will also need to replace the following parts when installing the final drive. These can be found in the Drivetrain section.
