This kit replaces 2008-2017 WRX STI rear calipers and rotors.
This kit can also allow for an upgrade of 2015+ WRX calipers and rotors with the equivalent STI calipers from the same year.
Included is everything needed to complete this conversion for the rear.
While this job is not difficult, it is always suggested to have a professional mechanic install anything that has to do with the braking system of a road car. IMPORTANT: This kit is ONLY compatible with 2008-2017 Impreza WRX STI and 2015+ Subaru WRX models.
If you are looking for the same kit for a 2008-2014 Impreza WRX model, this kit WILL NOT WORK as the bolt pattern is different from the STI - Please send me a message if you are questioning fitment.
This kit replaces factory brakes with larger brakes on your 2015+ WRX.
Factory WRX wheels will not clear these brakes.
All Stock 18" STI wheels will clear these calipers.
(If you are trying to determine what wheels will fit on your car, look for wheels that would fit on a 2008+ WRX STI.)Note: You will need to trim your WRX brake dust shields to allow for fitment of the larger STI sized rotors. These are in new remanufactured condition.
All threads are original and have not been repaired.
All hardware is brand new including the bleeder screws and pistons. Included in this kit are two rear calipers, all caliper hardware, two rear brake rotors as well as new pads.
This is everything you will need to install the larger size STI 2 Piston Rear calipers on your WRX or replace the Factory STI Calipers and rotors on a 2008-2017 WRX STI.The calipers will come powder coated black with white STI decals as shown in the listing images and can be installed as is. These calipers are shipped next day via

FAQs
Q1: What is the difference between OEM and Aftermarket parts, and how do I select the right quality level for my needs?
A: OEM (Original Equipment Manufacturer) parts guarantee exact fit and factory quality, typically at a higher cost. Our Aftermarket parts are sourced from certified manufacturers, often offering comparable performance and superior value. We clearly label all products to allow the customer to make an informed choice based on budget and required lifespan.
Q2: Since you are a global supplier, how do I calculate total shipping costs and estimated delivery time to my country/region?
A: Shipping costs are calculated based on part dimensions, weight, and the destination country during checkout. We offer multiple options (e.g., Economy, Express) with transparent, real-time tracking. Delivery times are clearly displayed and factor in customs processing for international orders.
Q3: What is the warranty period on your auto parts, and what does the warranty actually cover?
A: Most new parts carry a minimum 12-month limited warranty covering defects in material and workmanship, excluding wear and tear and improper installation. The specific warranty details (period and coverage) are clearly listed on each product page.
