The G20 BMW 3 Series is a versatile and stylish platform that’s perfect for personalization. Whether you drive the sporty M340i or a more understated trim, the G20 offers plenty of potential for enhancements that improve performance, aesthetics, and driving pleasure. If you’re looking to take your G20 to the next level, here are the top 5 modifications every owner should consider.
1. Aftermarket Wheels and Tires
Swapping out the factory wheels is one of the quickest ways to upgrade the appearance and performance of your G20 3 Series. Opt for lightweight, forged wheels from brands like HRE, Vossen, or BBS for improved handling and a more aggressive stance. Pair them with high-performance tires, such as Michelin Pilot Sport 4S or Pirelli P Zeros, to boost grip and cornering capabilities.
Whether you’re going for a sporty, track-ready look or a clean luxury aesthetic, the right wheel and tire combo transforms the car’s overall presence.
Benefits:
- Enhanced styling and stance
- Improved grip and cornering performance
- Reduced unsprung weight for better handling
2. Performance ECU Tune
The G20 3 Series features powerful turbocharged engines, making them excellent candidates for a performance ECU tune. By optimizing boost pressure, fuel maps, and ignition timing, an ECU tune can unlock significant horsepower and torque gains. For example, a stock M340i can easily exceed 400 horsepower with the right tuning solution.
Brands like Bootmod3 and MHD offer reliable and customizable tunes for the G20, allowing you to switch between performance maps for daily driving, track use, or fuel efficiency.
Benefits:
- Increased horsepower and torque
- Improved throttle response
- Customizable performance profiles
3. Aero Kit
Enhance the sporty look of your G20 with an aero kit. Carbon fibre add-ons like front splitters, side skirts, rear diffusers, and spoilers not only improve aerodynamics but also give the car a race-inspired aesthetic. certain lightweight components also reduce drag and increase downforce, especially at higher speeds.
Brands like CT Carbon and MHC offer high-quality kits specifically designed for the G20, ensuring a perfect fit and premium finish.
Benefits:
- Aggressive and sporty appearance
- Improved aerodynamics and stability
- Lightweight construction
4. Exhaust System Upgrade
If you want your G20 3 Series to sound as good as it looks, an aftermarket exhaust system is a must-have. Upgrading your exhaust not only enhances the car’s sound profile—giving it a deeper, more aggressive tone—but can also improve airflow for slight performance gains.
Popular options include Remus, Akrapovič, and Cobra, which offer systems tailored to your sound and performance preferences. Some exhausts even include valve control, allowing you to switch between quiet and loud modes.
Benefits:
- Enhanced exhaust note
- Slight gains in horsepower and torque
- Lightweight materials like titanium or stainless steel
5. Suspension Upgrades
The G20 3 Series strikes a good balance between comfort and performance, but upgrading the suspension allows you to tailor the car’s handling to your needs. Adjustable coilovers or lowering springs improve the car’s cornering ability, reduce body roll, and give it a more aggressive stance.
Brands like KW Suspension, Bilstein, and H&R offer suspension kits that cater to both spirited driving and daily use, ensuring a smooth ride while delivering enhanced performance on twisty roads or the track.
Benefits:
- Improved cornering and stability
- Adjustable ride height and stiffness
- Sporty, lowered stance
Honorable Mentions:
- Dechroming: Replace chrome trim with gloss or matte black accents for a stealthier look.
- Intake System Upgrade: Improve airflow and turbo spool with a high-performance intake system.
- Custom Interior Trim: Add carbon fiber, Alcantara, or custom accents to elevate the cabin’s luxury feel.
