How to Custom Build a Subaru Crosstrek: Your Complete Guide

If you’ve ever looked at a Subaru Crosstrek and thought, “How can I make it truly my own?” you’re in good company. The Crosstrek is a versatile, adventure-ready crossover that responds incredibly well to customization—from bold off-road builds to sleek city upgrades. Whether you’re customizing for improved performance, rugged trails, everyday utility, or unique style, you’ll find countless opportunities to tailor a Crosstrek exactly to your needs and personality.

Let’s break down everything you need to know to custom build your Subaru Crosstrek, covering options for new orders, aftermarket mods, practical advice, costs, and more.


1. Understanding Custom Crosstrek Options

Customizing your Subaru Crosstrek can mean two primary things:

  • Ordering a Crosstrek with your preferred features from the factory
  • Upgrading or modifying your Crosstrek with aftermarket parts and accessories

Both approaches have unique advantages; many Crosstrek enthusiasts mix and match for a truly unique ride.


Factory Customization: Build & Order Your Crosstrek

Ordering a new Crosstrek straight from the manufacturer provides a solid foundation with your ideal selection of:

  • Trim level (e.g., Base, Premium, Sport, Limited)
  • Exterior color
  • Interior fabric and color scheme
  • Engine and transmission options (where offered)
  • Tech and safety packages (navigation, eyesight, heated seats, etc.)
  • OEM (Original Equipment Manufacturer) accessories like all-weather mats, roof racks, or splash guards

This route is best if you want your car to arrive tailored to your specifications and with a full manufacturer warranty covering your choices.


Aftermarket Customization: Performance, Looks, Off-Road, and More

Once your Crosstrek is home, or if you already own one, the world of aftermarket upgrades opens up. This is where you can transform your Subaru from stock to standout! Common reasons Crosstrek owners customize after purchase include:

  • Enhancing off-road or overland capability
  • Improving on-road handling or speed
  • Updating the look (aggressive, sporty, rugged, or urban)
  • Upgrading comfort or tech
  • Expanding overall utility

2. Steps to Customizing Your Subaru Crosstrek

Let’s break down the customization process so you can plan your build efficiently and effectively.

1. Define Your Goals

Every build starts with a vision. Ask yourself:

  • Will you be using your Crosstrek for off-road adventures, daily commutes, road trips, or as a utility vehicle?
  • Are you focusing on form, function, or a blend of both?
  • What’s your budget, both upfront and ongoing?

2. Start With the Base: Stock Features and Factory Upgrades

If buying new, use the dealer’s “Build & Price” tool to pick the trim and factory options that best match your foundation. For example:

  • Choose all-wheel drive and higher ground clearance for off-road aspirations.
  • Opt for comfort and tech packages if that’s your priority.

3. Select Aftermarket Parts and Accessories

Once your Crosstrek is in your driveway, consider these popular upgrades:

Performance & Handling

  • Lift Kits: Raise the suspension for better ground clearance—great for tackling tough trails.
  • Wheels and Tires: Aggressive all-terrain tires and upgraded wheels improve grip, looks, and off-road readiness.
  • Suspension Upgrades: Stiffer or adjustable shocks and struts enhance handling whether on rocky tracks or winding roads.
  • Brakes: Upgraded brake pads or complete big brake kits offer better stopping power.

Exterior Modifications

  • Roof Racks and Cargo Carriers: Perfect for camping, biking, kayaking, or hauling extra gear.
  • Skid Plates: Protect vital underbody components from rocks and debris.
  • Lighting: LED bar lights, fog lights, and auxiliary lights improve night visibility and add rugged flair.
  • Body Armor: Rock sliders, bumper guards, and custom grille inserts add both style and rugged utility.

Interior Upgrades

  • All-Weather Floor Mats and Cargo Liners: Preserve your interior from the mess of outdoor adventures.
  • Aftermarket Audio or Navigation: Superior sound systems or more advanced navigation than what the factory offers.
  • Seat Covers and Organizers: Custom covers for durability and interior accents, plus storage solutions for road trips.

Engine and Exhaust

  • Performance Air Intakes: Boost throttle response and a subtle performance bump.
  • Cat-Back Exhausts: Add a sportier sound and (in some cases) modest power increases.

4. Seek Professional Installation When Needed

Some upgrades, like light bars, basic racks, and mats, are perfect DIY projects. More complex modifications—especially suspension, electrical work, and engine upgrades—are best left to professionals with Crosstrek experience.

5. Tune and Test

After installation, test drive your build in environments it’s meant for. Off-road mods? Hit a trail. Audio upgrades? Take a favorite playlist for a spin. Tweak and fine-tune as you go.


3. Benefits of Customizing Your Subaru Crosstrek

Customizing your Crosstrek unlocks a variety of benefits:

  • Enhanced Performance: Upgrades let you tackle tougher trails or improve on-road manners.
  • Personalized Style: Create a look that turns heads or subtly refines your SUV.
  • Utility for Your Lifestyle: Add the perfect mix of cargo, camping, or sporting accessories for work and play.
  • Increased Value (for You): While not all mods add to resale value, customizing can make your vehicle irreplaceable to you.

4. Potential Challenges When Customizing

Every project has obstacles. Here’s what to expect:

  • Warranty Concerns: Some aftermarket parts may void portions of your factory warranty—always check first.
  • Compatibility: Not every part fits every trim or year. Confirm fitment before ordering.
  • Installation Complexity: Some mods require special tools, knowledge, or alignment.
  • Budget Management: Costs can add up quickly; planning prevents “mod creep.”

5. Practical Tips and Best Practices

  • Start Small: Begin with essentials (tires, mats, lights) and work toward bigger projects (lift kits, exhaust).
  • Prioritize Needs Over Trends: Choose mods that suit your growth as an owner and adventurer, not just what’s popular.
  • Document Everything: Keep records of upgrades for maintenance and resale.
  • Join the Community: Local or online Crosstrek groups offer support, troubleshooting, and inspiration.
  • Budget Accordingly: Price each mod—including installation and tax—before buying. Watch for bundle deals when possible.

Shipping & Cost Optimization Tips

  • Consolidate Orders: Order multiple parts from one vendor to save on combined shipping.
  • Compare Local and Online: Sometimes local shops can order parts at similar or lower cost with free shipping.
  • Check for Free or Discounted Shipping: Many vendors offer these at certain price thresholds.
  • International Shipping: If importing, factor in fees, taxes, and delivery times. Some specialty mods may be worth the extra cost.
