Description

The HKS Body Kit Type-S is a comprehensive aerodynamic package engineered to blend functional beauty with aggressive styling for the GR Corolla. Born from HKS’s racing heritage and validated through CFD analysis and wind tunnel testing, each component—front spoiler, side skirts, rear spoiler, and rear wing—is designed to improve high-speed stability, braking performance, and aerodynamic balance. This kit delivers tangible on-track benefits while dramatically enhancing the car’s wide-body stance with a purposeful, race-inspired aesthetic.

Product Concept

This kit embodies the principle that performance and style are inseparable. Every element is styled with intent and validated through aerodynamic simulation and real-world testing at Fuji Speedway. It transforms the GR Corolla’s presence and dynamics, offering a cohesive look that communicates serious capability.

Product Highlights

🏁 Aerodynamic Performance Validated on Track
Extensive testing at Fuji Speedway confirmed measurable improvements in driving dynamics:

• Improved Braking Stability

• Reduced Understeer

• Enhanced Rear Stability

• Smoother, More Predictable Behavior at the Limit
  The kit is proven at speeds over 200 km/h, ensuring both effectiveness and durability.

🌬️ CFD-Optimized Components

• Front Bumper Spoiler (+45mm): Inherits HKS time attack DNA with integrated carbon fiber barge panels to manage wheel well airflow. CFD-optimized to reduce drag and increase front downforce.

• Rear Wing (FRP): A striking centerpiece. Its shape, position, and angle were optimized via CFD for low drag and high downforce. One-piece FRP molding ensures a clean, beautiful design that sits lower than the factory antenna.

• Rear Spoiler with Diffuser Fins: Features integrated fins underneath that connect visually and functionally to the factory diffuser, aiding rear-end airflow management.

✨ Cohesive, Aggressive Styling

• Side Skirts: Provide a simple, flowing profile that complements the factory lines, with provisions for adding HKS emblems for a personalized touch.

• Complete Wide-Body Integration: The kit is designed to match and enhance the factory wide-body flares, creating a planted, aggressive stance that looks born from the factory.

🔧 Optional Fender Molding (+8mm)
For an even more aggressive look without extreme width, HKS offers Fender Molding that extends each fender by +8mm. This meets Japanese safety standards, prevents tire protrusion with wider wheels, and maintains easy repairability with a separate bumper/fender structure.

Performance Philosophy

• Goal: To offer a significant aerodynamic and visual upgrade derived from HKS’s engineering prowess. The focus is on real-world performance gains—improved stability, balance, and driver confidence at high speeds—while delivering a dramatically improved, motorsport-inspired appearance.

• Focus: The definitive aero kit for the track-focused enthusiast who values both looks and science. It is designed for owners who drive their GR Corolla aggressively on track or backroads and want the aerodynamic advantages and commanding presence of a race-bred design.

Installation & Finishing

• 🔧 Professional Installation & Painting Mandatory
  This is a full bodywork package requiring professional installation by an experienced body shop. All components require professional painting to match your vehicle. Installation utilizes a combination of provided screws and high-strength adhesive tape.

• ⏱️ Total Installation Time: Allow approximately 8+ hours of total labor for the full kit installation and finishing.
