STI Front Lip – Subaru BRZ VFL (SG517CA100)
Original Subaru STI aero – precise fitment, premium quality, subtly sporty.
The STI front lip with part number SG517CA100 is the factory-developed aerodynamic upgrade for the Subaru BRZ pre-facelift. No reproduction, no fiberglass replica – this is a genuine STI component from Subaru’s performance program, delivering the OEM-level finish and durability expected from factory aero parts.
Visually, the lip integrates seamlessly with the front bumper and gives the BRZ a lower, wider, and more dynamic presence without looking exaggerated.

Appearance & Design Effect
The STI lip extends the front slightly downward and outward, giving the BRZ a noticeably flatter and sportier stance. The factory design language remains intact – this is not an aggressive track-only add-on, but OEM performance with understatement.
Painted in body color, it creates a clean OEM+ look. In black, it adds a defined contrast line that sharpens the lower edge of the bumper for a more performance-focused appearance.
Legality & Registration
There are no certification documents or approval papers available for this component.
Registration is therefore only possible via individual inspection and depends on the specific inspector. As a genuine STI part, some inspectors may accept it as a high-quality OEM component – however, approval cannot be guaranteed.
For track or dedicated performance vehicles, usage is generally unrestricted.
Benefits
OEM-level fitment – no modifications required

Plug & play installation
Primed – fully customizable in any desired color
Conclusion
The STI SG517CA100 front lip is one of the most refined ways to enhance the front of the BRZ VFL. Not loud, not overstyled – but factory-inspired, functional, and cleanly executed.
For those who appreciate OEM performance with style.
