Introduction: Why Upgrade Your Interior Pillars?
For owners of the 2014 Subaru WRX STI hatchback, the interior pillar trims represent both a vulnerability and an opportunity. The standard fabric-covered A, B, and C-pillar trims are prone to wear, fading, and a generally cheap feel that betrays the vehicle's performance pedigree. Upgrading to higher-quality materials like OEM suede, Alcantara, or premium vinyl isn't just about aesthetics—it's about transforming the driving experience and preserving your investment. This comprehensive guide will walk you through the entire process of performing a 2014 STI hatch interior pillar swap, from proper removal techniques that prevent broken clips and rattles to the best practices for cleaning and protecting your new trims and existing interior plastics. Whether you're looking to customize, upgrade, or repair, this process will elevate your STI's interior from mundane to exceptional.
Essential Tools and Materials
Before beginning your interior pillar removal project, gathering the right tools is crucial for success. Using improper tools is the leading cause of broken clips and damaged panels, which can lead to frustrating rattles later. The essential toolkit for this project includes:
- Plastic trim removal tools: These are non-negotiable. Unlike metal tools, plastic trim tools won't scratch or damage your interior surfaces. A set typically includes various shaped tools for different prying scenarios.
- Socket set with extensions (10mm socket for seatbelt bolts)
- Phillips head screwdriver
- Trim clip removal pliers
- Flashlight or work light
- Microfiber towels
- Interior cleaner and protectant
For the replacement trims themselves, you have several options. OEM Subaru parts from higher trim levels offer perfect fitment but can be expensive. Aftermarket options include Alcantara-covered panels or vinyl-wrapped trims. For a 2014 STI hatchback, compatible pillars typically come from 2011-2014 models, but always verify compatibility before purchasing. Websites like Genuine Subie Parts offer OEM components, while Subaru forums often have members selling quality used parts.
Pillar Removal Techniques: A, B, and C-Pillars
Proper removal technique is critical for avoiding damage during your DIY car interior upgrade. The process requires patience and a gentle touch—these panels weren't designed for frequent removal.
A-Pillar Removal
The A-pillar trim houses the curtain airbag, so extra caution is needed. Start by gently pulling the weatherstripping from the door frame to expose the edge of the trim. Insert your plastic trim tool between the trim and the windshield side, working from top to bottom. You'll feel the clips release with a slight popping sound—never yank or force the panel. Once all clips are released, carefully disconnect any wiring for the tweeter or ambient lighting if equipped.
B-Pillar Removal
The B-pillar is more complex due to the seatbelt mechanism. Begin by removing the seatbelt bolt cover—this small plastic piece snaps off with careful prying. Underneath, you'll find a Torx bolt securing the seatbelt mechanism. Use the appropriate socket to remove this bolt—do not attempt to remove the trim without first removing this bolt. Once the seatbelt is free, use your trim tools to release the clips holding the upper and lower B-pillar trims. The upper section typically pulls toward the interior, while the lower section may have clips that release upward.
C-Pillar Removal
The C-pillar trim in the hatchback integrates with the rear interior panels. Start by removing the rear seat side bolsters if necessary for access. The C-pillar trim usually has clips along the edge and may be secured with a screw behind the seatbelt access panel. Gently pry along the edge where the trim meets the headliner, working your way around until all clips release. Be particularly careful with the C-pillar as excessive force can cause visible deformation in the headliner area.
Installation of New Pillar Trims
Installing your new pillar trims is essentially the reverse of removal, but with several crucial considerations for ensuring a rattle-free result:
- Inspect all clips: Before installation, check each clip on the new trim pieces. Replace any that appear worn or damaged with new OEM clips—this small investment prevents future rattles.
- Test fit: Before fully securing any trim, do a test fit to ensure all clips align properly with their receptacles.
- Secure wiring: For trims with electrical components, use zip ties to secure wiring away from moving parts and prevent vibrations.
- Sequence matters: Install the trims in the correct order—typically A-pillars first, then B-pillars, then C-pillars. This ensures proper alignment and prevents interference between components.
- Final check: Once all trims are installed, gently press along each edge to ensure all clips are fully seated. Take the car for a short test drive on varied road surfaces to listen for any rattles that need addressing.
Interior Trim Care and Maintenance
After completing your 2014 STI hatch interior pillar swap, proper maintenance will keep your new trims looking their best. Different materials require different care approaches:
Cleaning and Protecting Alcantara/Suede
Genuine Alcantara and suede require specific care to maintain their texture and appearance. Never use harsh chemicals or abrasive brushes. Instead, use a soft-bristled brush to gently lift dirt and a specialized Alcantara cleaner for stains. For protection, consider a fabric protector designed specifically for synthetic suedes—test any product in an inconspicuous area first.
Plastic Trim Care
The surrounding interior plastics benefit from regular cleaning and protection. Use a pH-balanced interior cleaner and a soft microfiber towel to avoid scratching surfaces. For protection, choose a product that provides UV protection to prevent fading—especially important for vehicles with significant sun exposure. Avoid shiny, greasy products that create glare on the windshield and attract dust.
Restoring Faded Trim
If your existing plastics show fading or wear, consider a plastic restoration product before installing your new pillars. These products work by restoring the oils to dried-out plastics, bringing back the deep black color. For permanent results, dye-based products offer the most durable solution but require more careful application.
Troubleshooting Common Issues
Even with careful work, you may encounter some issues after your interior pillar swap. Here are solutions to common problems:
- Rattles: The most common post-installation issue. Identify the source by pressing on panels while driving. Felt tape or specialized anti-rattle pads applied to clip points often solve this.
- Misaligned panels: If panels don't sit flush, check for obstructing wiring or misplaced clips. Never force panels into place.
- Broken clips: If you break clips during removal, replace them with OEM equivalents—generic clips often don't fit perfectly and can cause rattles.
- Fading or discoloration: If new pillars don't match existing interior colors, consider using interior dye to achieve a perfect match.
