STM 20mm Wheel Spacers for 2015+ WRX / 2005+ STi

STM 20mm wheel spacer kit for 2015-2024 WRX and 2005-2021 STi. The spacers have a 5x114.3 bolt-pattern with a 56.1mm hub. Elongated wheel studs are required when running these spacers so we offer the ARP 100-7716 M12x1.25 studs to match if you don't already have them.

Sold as a pair of two spacers with or without ARP extended studs (100-7716).
*Elongated wheel studs ARE required when running these spacers!

USA Made:
CNC machined in-house at STM, these spacers are made from billet T6 6061 aluminum. The spacers also feature recesses on the back side for easy removal.

Lightweight Design:
Unlike other spacers, the STM design is just for your Subaru. Other spacers have a universal design that also fits 5x100, but with added weight. The STM spacers are designed with additional cutouts so they are lightweight and strong.

Vehicle Fitment:
2015-2024 Subaru WRX
2005-2021 Subaru STi
