Hey Subaru enthusiasts! Thinking about adding a little oomph to your 2016 Crosstrek? A spoiler can be a fantastic way to enhance its sporty look. Specifically, an STI spoiler can give your Crosstrek that aggressive edge while staying true to the Subaru family. Let's dive into what it takes to add an STI spoiler to your 2016 Crosstrek, covering everything from compatibility to installation.

Understanding STI Spoilers for Your Crosstrek

So, you're eyeing an STI spoiler for your Crosstrek. Great choice! The Subaru Tecnica International (STI) line represents the high-performance division of Subaru, and their spoilers are designed not just for looks but also for improved aerodynamics. When considering an STI spoiler, it's essential to know which models are compatible with your 2016 Crosstrek. Typically, spoilers from similar-year Impreza or WRX models might fit, but always double-check the dimensions and mounting points. You don't want to end up with a spoiler that looks out of place or, worse, doesn't fit at all!

Before you even think about buying, research is your best friend. Scour online forums, talk to fellow Crosstrek owners, and consult with Subaru parts specialists. They can offer invaluable insights into which STI spoilers are a direct fit or might require slight modifications. Remember, the goal is to enhance your Crosstrek, not create a Frankenstein's monster!

Also, keep in mind the material of the spoiler. STI spoilers often come in materials like fiberglass, carbon fiber, or ABS plastic. Each has its pros and cons regarding weight, durability, and cost. Fiberglass is lightweight but can be prone to cracking, carbon fiber is super strong but expensive, and ABS plastic offers a good balance of durability and affordability. Your choice should align with your budget and how you use your Crosstrek. If you're often off-roading, a more durable option might be better.

Finally, think about the finish. Do you want a spoiler that's already painted to match your Crosstrek, or are you comfortable getting it painted yourself? Pre-painted spoilers can save time and hassle, but they might not perfectly match your car's paint due to variations in batches or fading over time. Getting it painted locally ensures a perfect match but adds to the overall cost. Decisions, decisions!

Compatibility and Fitment

When it comes to adding an STI spoiler to your 2016 Subaru Crosstrek, compatibility is key. Not all STI spoilers are created equal, and what fits a WRX might not necessarily fit your Crosstrek. The Crosstrek has a unique rear hatch design, so you need a spoiler that complements those lines. Start by looking at spoilers designed for the Impreza hatchback, as the Crosstrek shares many similarities with it. However, even then, you'll want to confirm the mounting points and overall width to ensure a good fit. Getting the right fit is crucial not just for aesthetics but also for the spoiler's functionality. A poorly fitted spoiler can create drag, reduce fuel efficiency, or even come loose at high speeds.

So, how do you ensure compatibility? First, check the part numbers. If you're buying a used spoiler, ask the seller for the part number and cross-reference it with Subaru parts databases or forums. These resources can tell you exactly which models the spoiler was originally designed for. Second, take measurements. Measure the width of your Crosstrek's rear hatch and compare it to the spoiler's dimensions. Pay close attention to the location of the mounting holes. If they don't line up, you'll need to drill new holes, which can be risky if you're not experienced.

Another option is to look for aftermarket spoilers specifically designed for the Crosstrek that mimic the STI style. These spoilers are often made to fit the Crosstrek perfectly, eliminating the guesswork involved in retrofitting an STI spoiler. They might not be genuine STI parts, but they can still give you the look you're after without the hassle. Just make sure to choose a reputable brand that uses high-quality materials.

Don't forget to factor in the mounting hardware. Some spoilers come with all the necessary bolts, nuts, and washers, while others don't. Check what's included before you buy, and if anything is missing, source it separately. Using the correct hardware is essential for a secure and safe installation. Also, consider using sealant or weatherstripping to prevent water from seeping into the mounting holes and causing rust.

Installation Process: Step-by-Step

Alright, you've got your STI spoiler, and you're itching to install it. Here's a step-by-step guide to help you through the process. But remember, safety first! Always wear safety glasses and gloves, and if you're not comfortable with any step, don't hesitate to seek professional help.

1. Preparation is Key: Start by cleaning the area where the spoiler will be mounted. Use soap and water to remove any dirt or grime, then wipe it down with isopropyl alcohol to ensure a clean surface. This will help the adhesive (if any) bond properly.
2. Test Fit: Before you start drilling or sticking anything, do a test fit. Place the spoiler on the rear hatch and check the alignment. Make sure it sits flush and that the mounting holes line up (if applicable). This is your chance to make any adjustments before you commit.
3. Marking the Holes: If your spoiler requires drilling, carefully mark the location of the mounting holes. Use a pencil or marker to make precise marks. Double-check your measurements to avoid mistakes.
4. Drilling (If Necessary): If you need to drill holes, start with a small pilot hole and gradually increase the size until it matches the size of the mounting bolts. Use a drill bit designed for metal to prevent damage to your Crosstrek's body. Apply gentle pressure and keep the drill straight.
5. Applying Adhesive (If Applicable): Some spoilers come with adhesive strips or require you to apply adhesive. Follow the manufacturer's instructions carefully. Apply the adhesive evenly and avoid getting it on areas that won't be covered by the spoiler.
6. Mounting the Spoiler: Carefully align the spoiler with the mounting holes and attach it using the provided bolts and washers. Tighten the bolts gradually, alternating between them to ensure even pressure. Don't overtighten, as this could damage the spoiler or the Crosstrek's body.
7. Final Touches: Once the spoiler is securely mounted, clean up any excess adhesive or sealant. Inspect the installation to make sure everything is aligned and secure. Step back and admire your work!

Pro Tip: Consider having a friend help you with the installation. An extra set of hands can make the process easier and safer, especially when it comes to aligning the spoiler and tightening the bolts.

Potential Issues and How to Solve Them

Even with careful planning, you might run into a few snags during the installation process. Here are some common issues and how to tackle them:

• Misaligned Holes: If the mounting holes on the spoiler don't line up with the holes on your Crosstrek, you have a couple of options. You can try enlarging the holes on the spoiler slightly to allow for some wiggle room. Alternatively, you can drill new holes on your Crosstrek, but this should be a last resort.
• Weak Adhesive: If the adhesive isn't strong enough to hold the spoiler in place, you can supplement it with additional adhesive. Use a high-quality automotive adhesive designed for exterior applications. Make sure to clean the surfaces thoroughly before applying the adhesive.
• Water Leaks: If water is leaking into the mounting holes, you'll need to seal them properly. Use sealant or weatherstripping to create a watertight seal around the bolts and washers. This will prevent rust and corrosion.
• Spoiler Wobble: If the spoiler is wobbling or shaking, it could be due to loose bolts or an uneven mounting surface. Tighten the bolts and make sure the spoiler is sitting flush against the Crosstrek's body. If necessary, use shims to level the mounting surface.

Maintaining Your New Spoiler

So, you've successfully installed your STI spoiler – congrats! Now, let's talk about keeping it looking its best. Regular maintenance will not only preserve its appearance but also ensure it stays securely attached to your Crosstrek.

• Regular Cleaning: Just like the rest of your car, your spoiler needs regular washing. Use a mild soap and water solution to remove dirt, grime, and bird droppings. Avoid using harsh chemicals or abrasive cleaners, as they can damage the spoiler's finish. A soft cloth or sponge is your best friend here.
• Waxing: Applying a coat of wax to your spoiler will help protect it from the elements and keep it looking shiny. Use a high-quality automotive wax and follow the manufacturer's instructions. Waxing also makes it easier to remove bugs and other debris.
• Inspecting for Damage: Periodically inspect your spoiler for any signs of damage, such as cracks, chips, or fading. Address any issues promptly to prevent them from worsening. Small cracks can be repaired with epoxy or filler, while larger damage might require professional attention.
• Checking Mounting Hardware: Every few months, check the mounting bolts to make sure they're still tight. Loose bolts can cause the spoiler to wobble or even come loose, which can be dangerous. Tighten them as needed, but be careful not to overtighten.

By following these maintenance tips, you can keep your STI spoiler looking great and performing well for years to come. It's a small investment of time and effort that pays off in the long run.
