Here’s What Fits Your Subaru WRX (2015–2021) 

From the factory, the 2015–2021 Subaru WRX rolled out with 17–19” wheels, widths of 8–8.5 inches, and an offset of ET55. Like most modern Subarus, it uses a 5x114.3 bolt pattern and a 56.1mm hub bore. If you’re running hub-centric rings, make sure your ID matches that 56.1mm spec.

Now, that’s your baseline. But let’s be real — most WRX owners aren’t leaving their cars stock. Whether you’re daily driving, chasing grip, or going full send, we’ve broken fitment down into four categories: No Hassle, Slight Flex, All The Wheel, and YOYO (You’re On Your Own).

And yes — if you’ve got STI Brembos or opted for the big brake upgrade, keep brake clearance in mind before you click “add to cart.”

No Hassle Fitment

Bolt-on and go. Perfect if you want a style upgrade without drama, and in many cases, you can even reuse your stock tires.

Suggested Fitment:

• 18-19 x8 to x8.5 ET35–45

Recommended Wheels: 
Ultragram 18x8.5 ET35
Diverge 19x8.5 ET43
MRK1 18x8.5 ET43 

Scott’s Pick: Within this range, push the offset as aggressive as you can (closer to ET35). It’ll sit much better than stock without adding hassle.

Slight Flex Fitment

A little more attitude and grip. Still daily drivable without headaches, though depending on tire choice, you may need minor suspension tweaks.

Suggested Fitment:

• 18x9 to 18x9.5 ET40

Recommended Wheels: 

MRK1 18x9.5 ET40

All The Wheel Fitment

Aggressive, wide, and ready to show off. This is the sweet spot for enthusiasts who don’t mind dialing in camber or making adjustments to get it all to clear.

Suggested Fitment:

• 18x9.5 ET35

Recommended Wheels: 

Forged F1M 18x9.5 ET35

YOYO (You’re On Your Own)

You’re beyond recommended specs here. Fender rolling, trimming, suspension mods — expect it all. Only for those who don’t mind making things fit.

Suggested Fitment:

• 18x9.5 ET25
