2015-2021 Subaru STI

The CUSCO Front Side Power Brace (Part #6A1‑492‑FS) is designed for the front bottom suspension mounts of 2015‑2021 Subaru STI models. By linking the lower control arms and front suspension towers, it reduces chassis flex, enhances handling response, and gives the driver greater confidence during aggressive driving.

Constructed from high‑quality aluminum and finished in CUSCO’s signature blue powder‑coating, this brace is built for both street and track use. The installation kit comes complete with all necessary hardware, making the upgrade straightforward. It’s sold as a pair for both sides of the front suspension.

Key Features:

• Rigid aluminum construction for improved strength and durability

• Powder‑coated blue finish for corrosion resistance and visual appeal

• Connects front suspension lower mounts to reduce independent side flex

• Improves handling, steering response, and cornering stability
  

• Includes installation hardware

Why Choose This Brace?
If your STI shows signs of chassis flex, weak turn‑in, or less than ideal front end control — this brace corrects those issues by reinforcing the lower suspension layout. Whether you’re on street, canyon roads, or track day duty, you’ll feel a tighter, more responsive front end.
