Understanding Body Kits for the Subaru WRX

Your Subaru WRX is more than a car—it's a canvas for personal expression and performance tuning. One of the most impactful ways to transform its look and function is through a custom body kit. Whether you’re aiming for a track-ready stance or a street-savvy aesthetic, a well-chosen body kit can dramatically improve aerodynamics, reduce weight, and increase the vehicle’s resale value. This guide covers everything from material selection and fitment to installation and legal considerations, helping you make informed decisions every step of the way.

Before diving into styles and brands, it’s essential to understand what a body kit actually does. A typical kit includes front and rear bumpers, side skirts, and sometimes a rear diffuser or spoiler. More comprehensive kits add fender flares, hood scoops, and canards. The primary goal is to manage airflow: reduce lift at high speeds, channel air to brakes, and improve cooling. For WRX owners, a proper kit can also complement the car’s iconic boxer engine and symmetrical all-wheel drive by lowering the center of gravity and balancing weight distribution.

Types of Body Kits: Choosing Your WRX’s Personality

Body kits fall into several categories, each with distinct advantages and trade-offs. Your choice should align with your driving style, budget, and local regulations.

OEM-Style and OEM+ Kits

These kits mimic factory parts—think STI performance packages or JDM options. They maintain a clean, understated look while improving fitment and durability. Popular among daily drivers, OEM-style kits rarely attract unwanted attention from law enforcement. They’re often made from the same polypropylene as factory panels, making them easy to repair. However, they offer limited aerodynamic gains compared to more aggressive designs.

Widebody Kits

A widebody kit widens the WRX’s track, allowing for wider wheels and tires. This not only provides a menacing stance but also dramatically improves cornering grip. Brands like Rocket Bunny, Pandem, and Varis offer popular widebody options. Installation requires cutting or replacing fenders, so professional work is mandatory. Expect to invest significant time and money, but the visual and handling payoffs can be enormous.

Race-Style and Track-Oriented Kits

These prioritize function over form. They feature aggressive splitters, large canards, vented hoods, and deep diffusers to generate downforce and reduce drag. Materials are often carbon fiber or fiberglass. Race kits are lighter but more prone to damage from road debris. They’re ideal for track days, autocross, or weekend warriors. Notable brands include APR Performance, Voltex, and C-West. Be prepared for higher costs and possible street legality issues.

Custom and One-Off Kits

For owners who want something completely unique, custom fabrication is the route. A skilled shop can design and mold body panels from scratch using foam, clay, and fiberglass. The result is a pre-drilled, tailored fit. Costs can easily exceed $5,000 for a full custom kit, plus painting and installation. This option appeals to show car builders and those attending major tuning events.

Material Science: Fiberglass, Polyurethane, Carbon Fiber

The material of your body kit directly affects weight, durability, cost, and ease of installation. Here’s a breakdown of the most common options.

Material Weight Durability Cost Repairability Best For
Fiberglass Light Low – cracks easily Low to Medium Difficult – requires resin Budget builds, show cars
Polyurethane Medium High – flexible Medium Easy – can be sanded and painted Daily drivers, street use
Carbon Fiber Very light Medium – impact can cause splintering High Difficult – specialized Performance, weight savings

Tip: If you plan to lower your WRX on coilovers, polyurethane bumpers are less likely to crack on steep driveways. Carbon fiber looks incredible but can be expensive to replace after a parking lot mishap.

Compatibility and Fitment: Matching Your WRX Year

Body kits are not one-size-fits-all. Subaru WRX generations vary significantly in chassis dimensions, headlight shapes, and bumper mounting points. Always confirm the kit is designed for your model year:

  • VA chassis (2015–2021) – most aftermarket support
  • VB chassis (2022+) – newer kits are emerging, but compatibility is narrower
  • Previous generations (2002–2014) – still have strong aftermarket options from Japan and US brands

Check manufacturer listings and forums like Subaru Owner Resources or IWSTI.com for fitment reports. Many enthusiasts share their experiences with specific kits on NASIOC. Don’t hesitate to contact the seller directly and ask for test-fit photos.

Installation: DIY vs Professional

Installing a body kit is a meticulous process. While some owners tackle it in their garage, others wisely leave it to pros. Here’s a balanced look at both approaches.

Tools You’ll Need for DIY

  • Socket set, screwdrivers, trim removal tools
  • Drill and bits (for widebody riveting)
  • Sandpaper (various grits), filler primer
  • Paint spray gun or aerosol cans (if not using pre-painted)
  • Adhesive (3M tape, panel bond, or urethane seam sealer)

Professional Installation Considerations

If your kit requires cutting fenders (widebody), painting multiple panels, or complex wiring (such as integrated LED DRLs), hiring a reputable body shop is strongly advised. Installation costs range from $500 to $2,000 depending on complexity. A professional will ensure flush fitment, proper paint matches, and adhesion that lasts years.

Regardless of who does the work, proper surface preparation is non-negotiable. Degrease all mounting surfaces, test-fit every piece before drilling, and use high-quality hardware. Rust prevention is critical—apply touch-up paint to any exposed metal holes.

Painting and Finishing Touches

Matching your WRX’s factory paint requires skill. Even “paint code matched” rattle cans can vary. For best results, take your vehicle to an auto body shop that uses a spectrophotometer to blend the color. Key steps:

  1. Primer – Sand the kit with 400-grit, apply etching primer for fiberglass or plastic adhesion
  2. Basecoat – Build up color in thin, wet coats; allow flash time between layers
  3. Clear coat – Use a UV-resistant clear for gloss and protection
  4. Wet sand and buff – Remove orange peel for a mirror finish

Pro tip: Consider leaving certain components in matte black or carbon fiber weave for a race-inspired contrast. Many owners also wrap their kits instead of painting—vinyl wrap offers infinite color options and is removable later.

Before purchasing a body kit, research your local laws. Some states and countries restrict modifications that alter bumper height, protrude beyond factory dimensions, or reduce pedestrian safety. For example, California’s Vehicle Code limits bumper heights and prohibits sharp edges. In the EU, spoilers must not obstruct rear visibility. Common issues:

  • Aftermarket splitters exceeding 3 inches from bumper face
  • Removing factory crash impact foam to fit a kit
  • Enlarged exhaust openings that expose exhaust tips beyond bumper

Consult an automotive attorney or your local DMV if unsure. Most track-focused kits are not street legal everywhere. You may also need to notify your insurance provider—some policies exclude coverage for aftermarket modifications unless declared.

Maintenance and Longevity

A body kit adds visual drama but also demands care. Polyurethane parts need less maintenance than fiberglass, but both benefit from regular washing and occasional waxing. Avoid automatic car washes with brushes; hand wash using a microfiber mitt. Inspect mounting points every few months for loose fasteners or cracks. If you drive in snowy regions, salt can accelerate corrosion of metal brackets—rinse the underside frequently.

For widebody kits, the extra width increases the risk of curb rash on side skirts. Install protective plastic strips or consider sacrificing the front bumper lip as a wearable replacement part. Many manufacturers sell lip components separately.

Cost Breakdown: What to Expect

Body kit pricing varies wildly depending on material, brand, and complexity. A realistic budget for a complete upgrade includes:

  • Basic urethane kit (front/rear/sides) – $600–$1,200
  • Fiberglass race-style kit – $1,200–$2,800
  • Carbon fiber widebody – $3,000–$6,500+
  • Installation labor – $500–$2,500 (including painting)
  • Paint materials – $200–$600
  • Extra accessories (canards, splitters, diffuser) – $200–$800

Total investment can easily range from $2,000 to over $10,000. Factor in possible wheel and tire changes for widebody setups. The good news is that a well-executed body kit can increase your WRX’s resale value by 10–15% if the buyer values the aesthetic. Keep the original parts in storage to restore the vehicle to stock later.

Several manufacturers have earned reputations for quality and fitment specifically for the Subaru WRX.

  • Rocket Bunny / Pandem – Iconic widebody designs, available through Good Fabrications (US distributor)
  • Varis – Japanese carbon fiber excellence, often seen at SEMA
  • Vis Racing – Affordable fiberglass and carbon fiber options for multiple generations
  • OEM+ (Subaru / STI) – Genuine factory parts from Subaru Parts Pro
  • Duraflex / Extreme Dimensions – Budget polyurethane kits widely available on Amazon and eBay

Always read multiple reviews and look for customer photos before purchasing. Avoid kits with no return policy or that are sold “as is” with no fitment guarantee.
