The HKS Type-S Front Bumper Spoiler for the GR Corolla is not just a styling add-on — it is a CFD-designed aerodynamic component developed to improve front-end stability, airflow management, and high-speed composure.
Borrowing design cues from HKS time attack machines, this front lip extends the factory bumper by approximately 45mm, giving the GR Corolla a more aggressive stance while delivering measurable aerodynamic benefit.
This is aero with purpose.
HKS engineered the Type-S front spoiler using 3D CAD modeling and computational fluid dynamics (CFD) analysis to:
• Straighten airflow from the bumper to the under-panel
• Reduce turbulence at the front corners
• Improve air passage under the vehicle
• Increase front-end stability at speed
• Reduce drag while supporting downforce
Testing conducted at Fuji Speedway showed improvements in:
• Braking stability
• Reduced understeer
• Improved high-speed composure
• More controllable limit behavior
This isn’t cosmetic aero — it’s balanced chassis enhancement.
Adds visual aggression and increases aerodynamic surface area for improved front stability.
Carbon fiber end pieces streamline airflow at the front corners while adding subtle motorsport detail.
The shape transitions air smoothly toward the factory undertray, reducing chaotic air separation.
Maintains OEM body balance while introducing sharper, more purposeful front-end definition.
The Front Bumper Spoiler is constructed using high-quality FRP with carbon fiber components depending on configuration.
• Designed for strength and durability
• Lightweight construction
• Separate painting required
• Mounts using supplied hardware and double-sided tape
Professional installation is recommended.
Estimated installation time: Approximately 2 hours
Separate paint preparation required
Designed specifically for 2023–2024 Toyota GR Corolla
Always test-fit prior to paint.
Vehicle: 2023–2024 Toyota GR Corolla
Engine: G16E-GTS
Chassis: GZEA14H
While this listing focuses on the Front Bumper Spoiler, it is designed to integrate seamlessly with:
• HKS Type-S Side Skirts
• HKS Type-S Rear Spoiler
• HKS Type-S Rear Wing
For customers building a complete aero package, the full Type-S system enhances overall balance.
This front spoiler is ideal for:
• GR Corolla owners wanting functional aero
• Track and spirited street drivers
• Time attack-inspired builds
• Owners wanting improved front stability at speed
• Enthusiasts who want aggressive styling without compromising airflow
If you’re building a serious GR Corolla, front aero should do more than look good — it should perform.
Does this increase downforce?
Yes — through airflow straightening and underbody management, it improves front-end stability and reduces lift at speed.
Is this just cosmetic?
No. This was developed using CFD analysis and tested at Fuji Speedway for measurable handling improvements.
Does it require cutting?
No major structural modifications required, but professional installation is recommended.
Does it come painted?
No. Separate painting is required.
Will this fit with other aftermarket body kits?
Designed specifically around the OEM GR Corolla bumper.
