Ansix Rear Sway Bar Geometry Correction Mounts – 2013–2026 Scion FR-S / Subaru BRZ / Toyota GT86 & GR86

When you lower a BRZ/FR-S/86/GR86, rear sway bar geometry quickly moves away from ideal. In a properly set up suspension, sway bar end links should sit perpendicular to the lower control arm and perpendicular to the sway bar arm. Once the car is lowered, the end link angles change, the sway bar’s effective rate becomes less linear, and the rear of the car can feel less predictable—especially on corner entry and over bumps.

The Ansix Rear Sway Bar Geometry Correction Mounts reposition the rear sway bar higher to bring your suspension back toward ideal geometry on lowered cars. The kit also provides three fore/aft mounting positions to fine-tune alignment with adjustable sway bars that have multiple end link holes. On first-gen cars, this kit converts the rear sway bar mounting from the subframe to a direct chassis-mounted configuration similar to the second-generation BRZ.

Key Features

• Corrects Lowered-Car Geometry: Raises the sway bar mounting position to improve end link angles and restore more linear sway bar behavior.
• Improves Rear Predictability: Helps the rear end feel more consistent and controlled during cornering and transitions.
• 3-Position Fore/Aft Adjustment: Dial in ideal geometry, especially useful with adjustable sway bars featuring multiple mounting holes.
• Chassis-Mount Conversion (Most Applications): On non-second-gen BRZ applications, converts the sway bar mounting from subframe-mounted to chassis-mounted.
• Lower Weight on Stock BRZ Setup: On stock BRZ configurations, removing the rear sway bar mount frame can reduce weight by approximately 5.5 lbs.

Why We Like It

Lowering a car without addressing sway bar geometry is one of the easiest ways to lose consistency in how the rear end responds. This kit is the “missing piece” that helps your rear sway bar work the way it’s supposed to—especially if you’re serious about handling balance, track consistency, or simply want a more planted, predictable rear on the street.

Confirmed Fitment

• 2013–2016 Scion FR-S
• 2013–2026 Subaru BRZ
• 2013–2026 Toyota GT86 / GR86

Installation Notes

• Cutting Required: Cutting the stock brackets off the subframe is required on all cars except the second-generation Subaru BRZ.
• On the second-gen BRZ (which is chassis-mounted from the factory), the install is simpler and does not require cutting the subframe brackets.
• Recommended for lowered vehicles; use the three fore/aft positions to optimize end link angle and sway bar alignment.
• Professional installation is recommended due to cutting requirements on most applications.

Compatibility & Disclaimers

Intended for the vehicles listed above. This kit is designed to improve sway bar geometry primarily on lowered cars. Installation may require permanent modification (cutting) on most applications; measure carefully and follow the manufacturer’s instructions. Always verify sway bar, end link, and exhaust clearance after installation.
