Based on industry surveys of automotive enthusiast forums, an estimated 65% of 2011-2014 Subaru WRX STI hatchback owners report issues with their stock fabric pillar trims, including fading, wear, and a general dissatisfaction with the interior's premium feel. This comprehensive guide addresses the most sought-after interior modification for these vehicles: the complete A, B, and C-pillar trim swap to higher-quality materials like OEM Alcantara or vinyl. We'll provide the exact techniques for executing a flawless 2014 STI hatch interior pillar swap that eliminates rattles, enhances aesthetics, and preserves your vehicle's value, transforming your driving environment from utilitarian to exceptional.
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.
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:
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.
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.
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.
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.
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.
Installing your new pillar trims is essentially the reverse of removal, but with several crucial considerations for ensuring a rattle-free result:
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:
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.
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.
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.
Even with careful work, you may encounter some issues after your interior pillar swap. Here are solutions to common problems:
The difficulty is moderate, requiring patience and proper tools more than advanced mechanical skills. The most challenging aspect is removing trim without breaking clips or damaging surrounding surfaces.
textEssential tools include plastic trim removal tools, a socket set with extensions, trim clip removal pliers, and a Phillips head screwdriver. Plastic tools are crucial for preventing scratches and damage.
Genuine Alcantara trims can be sourced from Subaru dealers, specialty automotive interior shops, or through Subaru forums where owners sometimes sell components from part-outs.
No, the pillar trims differ between sedan and hatchback models due to different roof lines and interior dimensions. Always verify compatibility before purchasing replacement parts.
Rattles are typically caused by loose clips or unsecured components. Remove the trim and ensure all clips are properly seated. Adding felt tape to contact points can prevent metal-to-plastic contact that causes noise.
