The Genesis G70, a sleek and sophisticated sports sedan, has carved a niche for itself in the luxury performance segment. With its agile handling, refined interior, and potent engine options, the G70 is a driver’s car at heart. For enthusiasts seeking to elevate its performance, the aftermarket offers a plethora of upgrades designed to enhance power, handling, and driving excitement. Here’s a deep dive into the key performance parts that can transform the G70 into a track-ready machine.
Engine Performance Enhancements
The G70’s 2.0L turbocharged inline-four or 3.3L V6 twin-turbo engine is already impressive, but aftermarket parts can unlock even more potential. A cold air intake is a simple yet effective upgrade, drawing in cooler, denser air to boost horsepower and torque. Brands like Injen and K&N offer high-flow intakes tailored for the G70.
For the exhaust system, a high-performance cat-back setup from manufacturers like AWE Tuning or Borla reduces backpressure and unleashes a deeper, more aggressive tone. These systems often include stainless steel components and sleek exhaust tips, combining function with aesthetics.
ECU tuning is another game-changer. Companies like Cobb Tuning provide remapped software that optimizes fuel delivery, ignition timing, and boost pressure, yielding significant power gains. For the 3.3L V6, gains of 50+ horsepower are achievable without major mechanical changes.
Suspension and Handling Upgrades
The G70’s stock suspension balances comfort and sportiness, but enthusiasts often seek sharper handling. Coilover kits from KW Suspension or Tein lower the ride height and offer adjustable damping, improving cornering stability and reducing body roll. Upgraded anti-roll bars from Whiteline enhance grip by minimizing body sway during aggressive maneuvers.
Polyurethane bushings replace stock rubber components, reducing flex and improving responsiveness. These upgrades collectively sharpen the G70’s already nimble chassis, making it a joy on twisty roads or track days.
Braking System Overhauls
Increased power demands better stopping power. High-performance brake kits from Brembo or Wilwood feature larger rotors and multi-piston calipers, providing fade-resistant braking and shorter stopping distances. Ceramic brake pads, like those from Ferodo, offer improved bite and reduced dust for daily drivers.
Wheels and Tires
Lightweight forged alloy wheels from companies like Advan or SSR reduce unsprung weight, enhancing acceleration and handling. Pair these with high-performance tires such as Michelin Pilot Sport 4S or Toyo R888R for maximum grip. A slight reduction in wheel diameter (e.g., 18” over 19”) can also improve tire sidewall compliance for better track performance.
Interior and Driver Engagement
For a more connected driving experience, consider a short throw shifter to reduce gear change times. Upgraded steering wheels with alcantara or carbon fiber accents add a sporty touch, while lightweight seats from Recaro or Sparco improve driver support during spirited driving.
The Genesis G70 is a versatile platform ripe for modification. Whether you’re chasing horsepower, sharper handling, or a more engaging drive, the right performance parts can transform it into a formidable machine. Always prioritize quality components and professional installation to ensure reliability and safety. With thoughtful upgrades, the G70 can rival—or even surpass—its luxury sports sedan rivals, offering a blend of sophistication and raw performance that’s hard to beat.
By carefully selecting and balancing these enhancements, drivers can tailor their G70 to their preferred style, turning every drive into an exhilarating experience.
