Infiniti G37 Racing Widebody

The Infiniti G37 (V36 platform) is a popular choice for “street-to-track” builds. While the car’s factory lines are elegant, several aftermarket manufacturers offer “racing” style body kits that range from purely aesthetic widebody conversions to functional aerodynamic setups. Below is a breakdown of the most prominent kits available for the G37 Coupe and Sedan.

1. Liberty Walk (LB-Works / LB-Nation)

Liberty Walk is perhaps the most famous name in the G37 widebody scene. Their kits are inspired by Japanese “Bosozoku” and GT racing styles, characterized by exposed rivets and massive fender flares.

• Style: Aggressive, low-slung, and wide.

• Components: Front bumper, front diffuser, side skirts, rear diffuser, rear wing (Ducktail or GT Wing), and the signature wide fenders.

• Material: Usually Fiberglass Reinforced Plastic (FRP).

• Purpose: Primarily for “Stance” and show builds, though it provides the width needed for extremely wide racing tires.

2. DarwinPRO Aerodynamics

DarwinPRO offers some of the most comprehensive “racing” kits for the G37, often incorporating carbon fiber elements and vented designs that mimic GT3-class race cars.

• Key Features: Their kits often include vented hoods (RR Style), trunk spoilers, and full widebody flares.

• BKSS Style: A popular choice for the G37 Sedan, providing a modern, sharp racing aesthetic that updates the older V36 styling.

• Functionality: Vented fenders and hoods help with heat dissipation and wheel well pressure relief.

3. Zele Performance

For enthusiasts seeking a more refined, “functional” racing look without the “over-fender” riveted style, Zele Performance is a prestigious Japanese tuner.

• Style: Clean, integrated, and aerodynamic.

• Components: Front bumper with enlarged air intakes, side skirts, and a unique rear bumper/diffuser setup.

• Reputation: Zele kits are known for exceptional fitment and are often seen on high-end JDM-style builds.

4. IPL (Infiniti Performance Line) Retrofits

The factory IPL kit is the most aggressive “OEM” option. Many G37 owners upgrade their base models to the IPL bumpers and side skirts for a “factory racing” look.

• Components: Aggressive front bumper with fog light deletes, sculpted side skirts, and a unique rear bumper.

• Advantage: Perfect fitment and retains the car’s original body lines while adding a sporty edge.

5. Custom Functional Aero (Time Attack Style)

For true racing applications (Time Attack), owners often mix and match components for maximum downforce:

• Front Splitters: Often custom-made from Alumalite or Carbon Fiber, extending several inches forward.

• Chassis-Mounted Wings: Large GT wings from brands like APR Performance or Voltex.

• Canards: Small winglets on the front bumper to help with front-end grip.

• Vented Fenders: Aftermarket fenders (like those from Fly1 Motorsports) that allow air to escape from the wheel arches, reducing lift.
