The All-Purpose 17" Wheel Fitment

This fitment is ready-to-bolt-on, typically without modifications, and provides a meaningful increase in wheel width over stock. 17” wheels keep weight and tire costs to a minimum, allowing for improved ride quality. The 17x9” ET42 wheels fit nicely under the WRX fenders and give the owner room to play with tire sizes without having to worry about camber or fender work. When it comes to 9” wheels, the ET42 offset keeps the wheel inboard closer to the suspension to give enthusiasts as much outer fender clearance as possible.

The Aggressive Street / Weekend Warrior 17" Wheel Fitment

This flush wheel fitment has great inner strut clearance and may require a touch of negative camber to clear the fenders. 17” wheels keep weight and tire costs to a minimum, allow for taller tire sidewalls, for those looking for more comfort on the street.

The 17x9” ET35 wheels sit 7mm closer to the fender edge in comparison to the 17x9” ET42 wheels listed under option 1, and in-turn offer 7mm of extra inner suspension clearance. This makes these wheels a great solution for WRX owners who want to run wide tires and avoid the use of spacers. On stock suspension these wheels will typically poke slightly past the fenders, therefore, a small amount of negative camber is recommended.

The Widest 17" Track/Race Fitment

Perfect for weekend track warriors and hard core racers seeking maximum tire sidewall support. These aggressive wheel specs will require supportive modifications commonly found on track cars.  17” wheels keep weight and tire costs to a minimum, allow for taller tire sidewalls, and will still clear factory Performance Package Brembo brakes.

Aftermarket coilovers with a slimmer silhouette in comparison to the stock struts are required. Not all aftermarket coilovers provide a slim enough silhouette to accommodate 9.5” wheels without the use of spacers, so please contact an APEX product expert if you have any questions. See high-level notes under each tire combination below, or contact one of our Subaru Product Experts by submitting a fitment request form to have a more detailed one-on-one conversation about your track/race car.

The Widest 18" Track/Race Fitment

This 18” fitment is best suited for more hardcore weekend track warriors and competitive club racers looking to maximize grip and overall performance. While the 9.5" wheels aren't very difficult to fit under the front fenders, there are many different tire sizes and compounds that can be used, some of which will require negative camber and fender rolling to prevent rubbing the fenders under suspension compression.

Aftermarket coilovers with a slimmer silhouette in comparison to the stock struts are required. Not all aftermarket coilovers provide a slim enough silhouette to accommodate 9.5” wheels without the use of spacers, so please contact an APEX product expert if you have any questions.
