The 2016 Subaru Crosstrek is a popular choice for those seeking a versatile and reliable compact SUV. It's known for its standard all-wheel drive, decent fuel economy, and ample cargo space. But what if you want to add a touch of sporty flair to your Crosstrek? That's where the STI spoiler comes in! Let's dive into everything you need to know about potentially adding an STI spoiler to your 2016 Crosstrek.

Understanding the STI Spoiler

When we talk about an "STI spoiler," we're generally referring to the rear spoiler found on Subaru's high-performance STI models, like the WRX STI. These spoilers are designed to enhance the vehicle's aerodynamics, providing increased downforce at higher speeds. This translates to improved handling and stability, especially during cornering. However, the impact of a spoiler on a Crosstrek, which isn't designed for high-performance driving in the same way as an STI, is more about aesthetics than pure performance gains for daily driving.

Spoiler Design and Functionality: The STI spoiler is designed not only to look good but also to improve airflow around the vehicle. The specific design elements, such as the angle and curvature of the spoiler, play a crucial role in how effectively it can reduce lift and improve stability. For a car like the WRX STI, this can be a significant advantage on the track or during spirited driving. However, for a Crosstrek used primarily for commuting and everyday tasks, the functional benefits are minimal.

Material and Build Quality: STI spoilers are typically made from durable materials like fiberglass, ABS plastic, or carbon fiber. These materials are chosen for their strength, light weight, and resistance to weather and impact. The build quality of an aftermarket spoiler can vary significantly, so it's crucial to choose a reputable brand to ensure that it can withstand the elements and daily wear and tear. Cheaper alternatives might fade, crack, or even detach over time, which could be both unsightly and potentially dangerous.

Aesthetic Appeal: Ultimately, one of the primary reasons Crosstrek owners consider adding an STI spoiler is for its aesthetic appeal. The spoiler can give the car a more aggressive, sporty look, setting it apart from other Crosstreks on the road. The visual impact can be significant, transforming the rear of the vehicle and adding a touch of personality. However, it's essential to consider whether the STI spoiler's style complements the overall design of the Crosstrek. A spoiler that looks out of place can detract from the car's appearance rather than enhance it.

Will an STI Spoiler Fit My 2016 Crosstrek?

This is the million-dollar question! While an STI spoiler might be made to fit on a 2016 Crosstrek with some modifications, it's crucial to understand that it's not a direct bolt-on. The mounting points and overall dimensions of the STI spoiler are designed for the WRX STI, which has a different body shape than the Crosstrek. This means you'll likely need to do some custom work to make it fit properly.

Measuring and Assessing Compatibility: Before you even think about purchasing an STI spoiler, take precise measurements of your Crosstrek's rear hatch. Pay close attention to the width, curvature, and existing mounting points. Then, compare these measurements to the dimensions of the STI spoiler you're considering. Look for any significant discrepancies that might make the installation particularly challenging. Keep in mind that even small differences can require significant modifications.

Potential Modifications Required: If you decide to proceed with the installation, be prepared for some level of modification. This could include drilling new mounting holes in your Crosstrek's hatch, fabricating custom brackets to adapt the spoiler to the vehicle's body, or even reshaping the spoiler itself to better match the contours of the Crosstrek. These modifications require skill, patience, and the right tools. If you're not comfortable with this type of work, it's best to seek professional help.

Aftermarket Options and Alternatives: Fortunately, there are aftermarket spoilers specifically designed for the Subaru Crosstrek. These spoilers are engineered to fit the Crosstrek's body lines and mounting points, making installation much easier and less prone to problems. While they may not have the exact same aggressive look as an STI spoiler, they can still add a sporty touch to your vehicle without the hassle of extensive modifications. Explore different styles and designs to find one that suits your taste and budget.

Installation Considerations

Okay, so you've decided you want to try and make this happen. What should you keep in mind during the installation process?

Professional Installation vs. DIY: Installing an STI spoiler on a Crosstrek is generally not a beginner-level DIY project. If you have experience with auto body work and are comfortable with drilling, cutting, and fabricating parts, you might be able to tackle it yourself. However, if you're not confident in your abilities, it's best to leave the installation to a professional. A professional installer will have the tools, knowledge, and experience to ensure that the spoiler is mounted correctly and securely, minimizing the risk of damage to your vehicle.

Tools and Materials Needed: Whether you're doing the installation yourself or hiring a professional, make sure you have all the necessary tools and materials on hand. This typically includes a drill, drill bits, measuring tape, masking tape, sandpaper, primer, paint (if necessary), adhesive, and a set of wrenches and sockets. Having everything readily available will streamline the installation process and prevent delays.

Step-by-Step Installation Guide (General):

1. Preparation: Clean the surface of your Crosstrek's hatch where the spoiler will be mounted. Use masking tape to protect the surrounding paint from scratches.
2. Test Fit: Hold the spoiler in place and check the alignment. Mark the locations for the mounting holes.
3. Drilling: Carefully drill the mounting holes, ensuring that they are properly aligned and sized.
4. Priming and Painting: If necessary, prime and paint the spoiler to match the color of your Crosstrek.
5. Mounting: Apply adhesive to the spoiler and attach it to the hatch. Secure it with bolts or screws.
6. Final Adjustments: Make any necessary adjustments to ensure that the spoiler is properly aligned and securely mounted.

Potential Problems and Solutions:

• Misaligned Holes: If the mounting holes are misaligned, you may need to enlarge them or drill new ones. Use a file or rotary tool to carefully adjust the holes until the spoiler fits properly.
• Weak Adhesion: If the adhesive is not strong enough, the spoiler may come loose over time. Use a high-quality automotive adhesive and ensure that the surfaces are clean and properly prepared before applying the adhesive.
• Rust Prevention: Drilling new holes can expose bare metal, which can lead to rust. Apply a rust inhibitor to the edges of the holes to prevent corrosion.

Alternatives to the STI Spoiler

If the idea of modifying an STI spoiler to fit your Crosstrek seems too daunting, don't worry! There are plenty of other options available.

Aftermarket Crosstrek-Specific Spoilers: As mentioned earlier, there are numerous aftermarket spoilers designed specifically for the Subaru Crosstrek. These spoilers are engineered to fit the Crosstrek's body lines and mounting points, making installation much easier. They come in a variety of styles and finishes, so you can find one that matches your taste and budget.

Lip Spoilers: Lip spoilers are a more subtle alternative to the traditional STI spoiler. They attach to the bottom edge of the rear hatch and provide a cleaner, more understated look. Lip spoilers are typically easier to install than larger spoilers, and they can still add a touch of sporty flair to your Crosstrek.

Other Exterior Modifications: If you're looking to customize the look of your Crosstrek, there are many other exterior modifications you can consider. These include aftermarket wheels, window tint, body kits, and custom lighting. Combining several of these modifications can create a unique and personalized look for your vehicle.

Cost Considerations

Before you jump into any modifications, it's important to consider the costs involved.

Spoiler Price: The price of an STI spoiler can vary depending on the material, brand, and vendor. Expect to pay anywhere from $200 to $800 or more for a genuine STI spoiler. Aftermarket spoilers may be less expensive, but the quality can vary.

Installation Costs: If you're hiring a professional to install the spoiler, labor costs can add significantly to the total price. Expect to pay several hundred dollars for installation, depending on the complexity of the job.

Painting and Materials: If the spoiler needs to be painted to match your Crosstrek's color, that will add to the cost. Factor in the price of paint, primer, and other materials.

Potential Hidden Costs: Be prepared for potential hidden costs, such as unforeseen modifications, additional hardware, or unexpected repairs. It's always a good idea to have a contingency fund to cover these expenses.

Final Thoughts

Adding an STI spoiler to your 2016 Subaru Crosstrek can be a fun way to personalize your ride and give it a sportier look. However, it's important to understand the challenges involved and weigh the costs and benefits carefully. If you're not afraid of a little DIY work and are willing to do your research, you can achieve a unique and eye-catching result.
