Why Modify the Genesis G70?
The Genesis G70 already offers an impressive blend of performance, style, and technology. But for enthusiasts and everyday drivers alike, modifying the G70 can take the experience to the next level. Whether you’re looking to improve speed, handling, aesthetics, or simply stand out on the road, the right mods can transform your driving experience. In this post, we’ll explore the best Genesis G70 modifications that deliver real value, backed by community feedback and expert opinions.
Performance Mods That Make a Difference
1. ECU Tune for More Power
An ECU tune is one of the most cost-effective ways to boost horsepower and torque. By recalibrating the engine control unit, you can unlock hidden performance potential—especially on turbocharged models like the G70 2.0T and 3.3T.
According to Burger Motorsports, their JB4 tuner for the G70 3.3T can add up to 100 horsepower with just a plug-and-play installation. For those wanting a noticeable performance bump without invasive mods, an ECU tune is a smart first step.
2. Cold Air Intake for Better Throttle Response
Upgrading the intake system improves airflow to the engine, resulting in faster throttle response and better engine sound. Brands like Injen and Stillen offer performance cold air intakes specifically designed for the G70 platform. These systems also enhance under-the-hood aesthetics.
3. Exhaust System for Power and Sound
A cat-back or axle-back exhaust system not only increases horsepower but also gives your G70 a throatier, sportier tone. Consider systems from ARK Performance or Borla that are known for quality and sound tuning.
Not only do you gain performance, but you also achieve a more aggressive and refined exhaust note that complements the car’s luxury-sport appeal.
Handling Upgrades That Matter
4. Lowering Springs or Coilovers
To improve stance and handling, lowering the G70 is a popular route. Lowering springs like Eibach Pro-Kit slightly reduce the ride height while maintaining daily drivability. For more aggressive setups, BC Racing coilovers allow for height and damping adjustability, giving you full control over how your car handles.
Many users on Genesis Forums recommend starting with lowering springs to test the look and feel before committing to coilovers.
5. Performance Tires and Lightweight Wheels
Wheels and tires directly affect handling, acceleration, and ride comfort. Swapping the stock wheels for forged alloys not only reduces unsprung weight but also allows room for wider, stickier tires. Consider brands like Enkei, Forgestar, or Apex that offer lightweight options that fit the G70 bolt pattern and offset.
Performance summer tires like Michelin Pilot Sport 4S or Continental ExtremeContact Sport dramatically improve grip and cornering confidence.
Visual and Interior Mods for Personalization
6. Aerodynamic Body Kits
Visual mods add personality to your ride. Front lips, side skirts, and rear diffusers from ADRO or Stillen not only improve downforce but also enhance the G70’s aggressive look. These kits are often made from lightweight carbon fiber or durable ABS plastic.
7. Custom Lighting Upgrades
Upgrading to LED interior lights, sequential turn signals, or smoked taillights adds a modern and premium feel to your G70. Many of these upgrades are simple plug-and-play installations that don’t require major rewiring.
8. Carbon Fiber Interior Accents
For the interior, carbon fiber dash trims, steering wheel overlays, and gear shift surrounds give your cabin a more performance-oriented look. They also help reduce visual wear over time, especially in high-touch areas.
Tech and Convenience Enhancements
9. Android Auto/Apple CarPlay Upgrade
Some early G70 models don’t have wireless Apple CarPlay or Android Auto. Aftermarket modules, like those from CarPlay Smartbox, allow for wireless connectivity, screen mirroring, and even video playback on the OEM infotainment screen.
10. Dash Cam Installation
Adding a dash cam not only helps with accident documentation but also protects your vehicle from vandalism and parking lot incidents. Hardwiring it into your fuse box keeps the install clean and out of sight.
Build the G70 That Reflects You
Modifying your Genesis G70 is more than just an upgrade—it’s a statement. With the right combination of performance, handling, visual, and tech modifications, you can tailor your vehicle to perfectly match your style and driving preferences.
Just be sure to always research thoroughly, choose quality parts, and consult with professionals when necessary to maintain safety and warranty considerations. Your dream G70 build is just a few mods away.
