How to Customize the 2015 Dodge Charger R/T: A Comprehensive Guide

If you own a 2015 Dodge Charger R/T, you already have a muscle car with impressive style and performance. Still, many Charger enthusiasts want to take things further, making their ride stand out both visually and under the hood. Whether you’re aiming for dramatic looks, improved speed, or a unique interior, customizing your Charger R/T has never been more exciting. Here’s a complete guide to making your 2015 Charger R/T truly your own.


Why Customize Your 2015 Dodge Charger R/T?

Personalizing your Charger R/T goes beyond just aesthetics. Custom modifications can:

  • Enhance performance and handling.
  • Improve comfort and daily usability.
  • Showcase your unique style.
  • Boost resale value, if done tastefully.
  • Make your driving experience more thrilling.

There are countless ways to approach customization, from body kits and engine mods to interior upgrades. Below, we’ll break down the most popular areas to consider, offer practical tips, and highlight what you need to know before starting.


1. Exterior Customization: Make a Statement

The first thing people see is your Charger’s exterior. From subtle touches to bold overhauls, here’s how you can transform that iconic muscle car body.

Body Kits and Aero Upgrades

Body kits can turn your Charger into a head-turner, giving it a wider, lower, and more aggressive stance.

  • Popular Options: Full body kits, front splitters, rear diffusers, side skirts, hood scoops, and spoilers.
  • Widebody Kits: Expanding wheel arches for a more muscular look; available for drivers wanting serious street presence.
  • Material Choices: ABS plastic, fiberglass, polyurethane, and carbon fiber each offer different looks, weights, and price points.

Key Steps to Installing a Body Kit:

  1. Research kit compatibility (ensure it’s designed for the 2015 R/T model).
  2. Consider professional installation — some kits require significant fitting or paintwork.
  3. Double-check local laws regarding ground clearance and exterior modifications.

Wheels and Tires

The right wheels change everything.

  • Larger Sizes: 20-inch or even 22-inch wheels fill the wheel wells and upgrade your stance.
  • Lightweight Alloys: Improve performance and style.
  • Performance Tires: Better grip, cornering, and acceleration.

Custom Lighting

Lighting upgrades serve both form and function.

  • LED Headlights and Taillights: Brighter and longer-lasting.
  • Sequential Turn Signals: Add a modern flair.
  • Underglow Kits: For show or event use—check legality.

Vinyl Wraps and Paint

Don’t forget about changing your car’s color and finish.

  • Vinyl Wraps: Non-permanent transformation, endless textures (matte, gloss, satin, chrome, carbon fiber).
  • Custom Paint: More expensive, but nothing beats the perfect shade applied by a trusted shop.

Practical Tip: Always have a plan before investing—decide your “theme” to avoid clashing styles.


2. Performance Upgrades: Unleash the Potential

Performance is at the heart of the Charger R/T experience. The 5.7L HEMI is a fantastic platform to build on.

Engine and Power Mods

  • Cold Air Intake Systems: Cooler air equals better combustion for a slight horsepower bump.
  • Performance Exhaust: Cat-back or axle-back systems add sound and flow, increasing power and generating that signature muscle car rumble.
  • Custom Engine Tunes: A professional ECU tune can extract serious gains, adjust shift points, and improve throttle response.
  • Throttle Body Upgrades: Quicker acceleration and crisp pedal feel.

Suspension and Handling

Handling is just as important as straight-line speed.

  • Lowering Springs or Coilovers: Improve stance and reduce body roll.
  • Upgraded Sway Bars: Sharper cornering, especially during spirited driving.
  • Performance Brakes: Bigger rotors and better pads help bring all that extra speed to a stop with confidence.

Forced Induction

For the ultimate power upgrade—superchargers and turbo kits.

  • Bolt-On Superchargers: Massive increase in horsepower; requires supporting mods and careful installation.
  • Cost Consideration: This is a big investment, so budget for supporting modifications (fuel systems, internals) and labor.

Practical Tip: Set a realistic budget and goal—do you want a street weapon, a show car, or a daily driver with extra punch?


3. Interior Upgrades: Comfort, Tech, and Style

Inside is where you spend most of your time. Make it your sanctuary.

Seating and Upholstery

  • Custom Leather or Suede Seats: Better feel, premium look.
  • Aftermarket Seat Covers: Protect and personalize at a lower cost.
  • Racing Seats: For serious track-goers or those who love the sporty feel.

Steering Wheel and Controls

  • Custom Steering Wheels: Carbon fiber, flat-bottom, or paddle shifter versions up the cool factor.
  • Shift Knobs and Pedals: Small touches that add personality.

Gauges and Displays

  • Digital Gauge Clusters: Modernize your dash with extra data.
  • Heads-Up Displays: Keep your eyes on the road with projected speed and navigation.

Audio and Infotainment

  • Aftermarket Head Units: Apple CarPlay, Android Auto, better sound.
  • Speakers and Subwoofers: Tune the audio experience to your taste.

Specialty Interior Accents

  • Carbon Fiber Trim Kits: Replaces bland plastic with race-inspired looks.
  • Custom Airbag Covers: For a unique focal point—ensure safety and compatibility.

Practical Tip: Choose upgrades that enhance your daily driving experience, not just appearance.


4. Tuning and Software: Get the Most From Every Mod

Tuning maximizes the benefit of your performance upgrades.

  • PCM (Powertrain Control Module) Tuning: Adjusts engine parameters for more power and better efficiency.
  • Custom Tunes: Tailored maps for your specific modifications.
  • Dyno Testing: Ensure your car is running safely and at its best.

Challenges with Tuning

  • Warranty Concerns: Some tunes may void your factory warranty.
  • Compatibility: Many tuners require specific software for 2015 models and later.

Tip: Work with a reputable tuner who specializes in Dodge vehicles and can provide after-support.


5. Best Practices and Practical Advice

Customization can be overwhelming—here’s how to do it smartly:

  1. Set a Budget: Customizing can get expensive fast. Prioritize key upgrades first.
  2. Do Your Research: Not all parts fit or work well together. Read reviews and consult experts.
  3. Professional Installation vs. DIY: Some upgrades, like body kits and engine internals, are best left to professionals.
  4. Check Local Laws: Some mods (like tint, underglow, and loud exhausts) may be illegal in your area.
  5. Plan for Insurance: Notify your insurer about major modifications to maintain coverage.

6. Cost Tips and Shipping Insights

Custom parts range widely in price, and so does shipping—here’s how to save:

  • Bulk Orders: Consider ordering multiple parts from the same supplier for combined shipping rates.
  • Watch for Sales: Many aftermarket parts retailers offer seasonal discounts.
  • Local vs. International Sellers: Domestic suppliers usually have cheaper and quicker shipping for big items, like body kits and wheels.
  • Return Policies: Check these before purchasing, especially for parts that may need custom fitting.
  • Shipping for Oversized Parts: Large items may incur freight shipping—if possible, pick up locally or order from regional suppliers.

7. Challenges to Be Aware Of

  • Fitment Issues: Not all aftermarket parts fit perfectly; sometimes trimming or custom mounting is required.
  • Installation Complexity: High-performance mods can stress other components—always upgrade supporting systems.
  • Resale Considerations: Highly personalized mods may limit your pool of potential buyers.
  • Quality Variability: Not all aftermarket parts are created equal; stick with trusted brands.

8. Bringing It All Together: Build Your Dream Charger R/T

Customizing your 2015 Dodge Charger R/T is a journey. Whether you start with a bold body kit, lightweight wheels, or a roaring exhaust, each step brings your vision to life. Prioritize safety, quality, and compatibility to enjoy your upgrades worry-free.

Remember, the best build is one that reflects your personality and meets your needs—there’s no single “right way” to customize your Charger R/T. Have fun, explore options, and turn that muscle car into a true extension of yourself.
