Joseph Weaver If you own a 2010 Subaru WRX, you must have wondered about the dimensions of the flywheel that it uses. The flywheel is an essential component of the vehicle’s powertrain system, responsible for transmitting power from the engine to the transmission. In this article, we will explore the different dimensions of flywheels used in a 2010 Subaru WRX.
Key Takeaways
- The 2010 Subaru WRX uses a single-mass flywheel that is 12.2 inches in diameter and 1.18 inches thick.
- The flywheel is made of high-strength steel for improved durability and performance.
- The flywheel can be resurfaced to restore its flatness and prevent clutch slippage.
- The use of lightweight flywheels can improve the vehicle’s acceleration but may cause excessive noise and vibrations.
Flywheel Dimensions
The flywheel used in a 2010 Subaru WRX is a single-mass flywheel that is 12.2 inches in diameter and 1.18 inches thick. The flywheel is made of high-strength steel to withstand the stresses of high-performance driving. The single-mass flywheel has a simpler design compared to a dual-mass flywheel, which eliminates the need for a damping mechanism that can add weight and complexity to the powertrain system.
Flywheel Material
The flywheel in a 2010 Subaru WRX is made of high-strength steel for improved durability and performance. The high-strength steel is designed to withstand the high torque loads generated by the engine and transmit them to the transmission with minimal power loss. The use of high-strength steel also improves the flywheel’s resistance to heat and wear, which can prolong its lifespan.
Flywheel Resurfacing
Over time, the surface of the flywheel may become uneven due to clutch slippage or wear. To restore the flywheel’s flatness, it can be resurfaced using a lathe or grinder. Flywheel resurfacing involves removing a small amount of material from the surface of the flywheel to make it smooth and even again. This process can help prevent clutch slippage and improve the performance of the clutch system.
Lightweight Flywheels
Some owners of 2010 Subaru WRXs may consider using lightweight flywheels as an upgrade. Lightweight flywheels are designed to reduce the rotating mass of the powertrain system, which can improve the vehicle’s acceleration and throttle response. However, there are some drawbacks to using lightweight flywheels. They can cause excessive noise and vibrations, especially at idle and low speeds. They can also make it more difficult to launch the vehicle smoothly from a stop.
Conclusion
The flywheel is an essential component of the 2010 Subaru WRX’s powertrain system. It is responsible for transmitting power from the engine to the transmission and plays a crucial role in the vehicle’s performance and drivability. The flywheel used in a 2010 Subaru WRX is a single-mass flywheel that is 12.2 inches in diameter and 1.18 inches thick. It is made of high-strength steel and can be resurfaced to restore its flatness. While some owners may consider using lightweight flywheels as an upgrade, it is important to weigh the benefits against the drawbacks before making a decision.
FAQ
Can I use a dual-mass flywheel in my 2010 Subaru WRX?
While a dual-mass flywheel can provide better damping and smoother operation, it is not recommended for use in a 2010 Subaru WRX. The WRX’s powertrain system is designed to work with a single-mass flywheel, and using a dual-mass flywheel can cause compatibility issues and potentially damage the powertrain system.
What is the recommended flywheel thickness for a 2010 Subaru WRX?
The recommended flywheel thickness for a 2010 Subaru WRX is 1.18 inches. Using a flywheel that is thinner than this can cause clutch slippage and premature wear, while using a flywheel that is thicker than this can cause excessive heat buildup and reduced performance.
