Put Every Horsepower to Work

All the power in the world doesn't mean much if it's getting lost on the way to the wheels. Upgrading your Subaru WRX drivetrain cuts down on unwanted movement through the driveline, so you get sharper shifts, better traction, and that locked-in feel where the car actually responds the second you do.

Want the upgrade you'll feel on literally every drive? A quality WRX short shifter cuts your shift throws way down for quicker, snappier gear changes. No sacrifice in reliability. Pair it with upgraded bushings, transmission mounts, and shift stops, and the whole setup tightens up even further.

And if you're chasing that proper sports-car feel, a 2022 WRX short throw shifter is hands-down one of the easiest ways to make every gear change something you look forward to.
