Step-by-step guide to installing a Billetworkz e-brake and climate control kit on a Subaru WRX 2015-2021. Learn tools, tips, and common mistakes.
Quick Answer
Yes, you can install the Billetworkz Interior Kit (Pro) on your Subaru WRX 2015-2021 yourself in about an hour with basic hand tools. Follow the steps below for a clean, secure fit.
Why the Billetworkz Interior Kit (Pro) Fits the WRX 2015-2021
The Billetworkz Interior Kit (Pro) is designed specifically for the Subaru WRX 2015-2021, so the e-brake button and climate control knobs match the factory dimensions. This means no cutting, drilling, or modification is needed—just a direct swap.
The kit uses CNC-machined billet aluminum with an anodized finish, giving a durable, consistent look across the controls you touch daily. The Hybrid Shift Knob included in the kit adds a performance-focused touch but is not required for the e-brake or climate control install.
If you're only upgrading the e-brake button or climate knobs individually, the same removal and installation principles apply, but the kit ensures color and finish match across all pieces.
Installation Steps
- Gather tools and prep the car: You'll need a flathead screwdriver, a small pick or trim removal tool, and a clean microfiber cloth. Ensure the car is off and the parking brake is engaged for safety. Check that the new e-brake button and climate knobs are the correct ones for your WRX 2015-2021 before starting.
- Remove the factory e-brake button: Gently pry the existing button off the e-brake handle using a trim tool or flathead screwdriver. It should pop off with light pressure—do not force it. If the button doesn't release easily, wiggle it side-to-side; avoid prying hard against the handle to prevent scratches.
- Install the new e-brake button: Align the new billet aluminum button with the handle and press it firmly until it clicks into place. Ensure it sits flush and doesn't rotate. Test the button by pressing it a few times—it should move smoothly without binding.
- Remove the factory climate control knobs: Pull each knob straight off the climate control unit. If they're tight, use a trim tool to gently lever them off, being careful not to damage the surrounding trim. Take a photo of the knob positions before removal to avoid mixing up left/right or temperature/fan knobs.
- Install the new climate control knobs: Press each new knob onto the corresponding shaft, aligning any flats or splines. Push until they seat fully and feel secure. Rotate each knob through its full range to confirm it's gripping the shaft properly and doesn't slip.
- Final check and cleanup: Reinstall any trim pieces you removed, wipe down the new parts with a microfiber cloth, and test all functions (e-brake, climate control) to ensure everything works. Keep the original parts in a safe place in case you want to revert to stock later.
