What size is the shift knob on a 2016 WRX?

The shift knob on a 2016 Subaru WRX has a diameter of approximately 4 inches (10 cm). This standard-sized shift knob provides a comfortable and ergonomic grip for drivers to smoothly engage the 6-speed manual transmission in this high-performance sports sedan.


Detailed Explanation


The 2016 Subaru WRX is a compact sports car known for its turbocharged engine, all-wheel-drive system, and engaging driving dynamics. As part of the vehicle's performance-oriented design, the shift knob plays an important role in providing the driver with a direct and tactile connection to the transmission.


Subaru engineers typically equip the WRX with a shift knob that measures around 4 inches (10 cm) in diameter. This size is considered an optimal balance, offering enough surface area for a secure grip without being overly large or bulky, which could hinder quick gear changes.


The shift knob material is also an important consideration. Many 2016 WRX models came equipped with a shift knob made of leather or a leather-wrapped design, providing a premium feel and enhanced grip compared to a bare metal or plastic knob.


Customization Options


While the factory-installed shift knob on a 2016 WRX is a 4-inch diameter unit, owners have the option to install aftermarket shift knobs of varying sizes and materials to personalize the driving experience.



  • Smaller shift knobs (3-3.5 inches) can provide a more nimble, race-inspired feel.

  • Larger shift knobs (4.5-5 inches) offer a more substantial grip for drivers with larger hands.

  • Alternative materials like aluminum, carbon fiber, or weighted shift knobs can also be installed to suit individual preferences.


Ultimately, the choice of shift knob size and material is a matter of personal preference, as long as it allows the driver to comfortably and confidently operate the 6-speed manual transmission in the 2016 Subaru WRX.
