Eibach 82105.31 25mm Front Sway Bar for Scion FR-S/Subaru BRZ/86

Vehicle Fitment

• 2013-2021 Scion FR-S
• 2013-2021 Subaru BRZ
• 2017-2021 Toyota 86

Fitment Notes

• Front sway bar only - not the rear bar and not a full front+rear kit
• Same "82105" prefix pattern as other Eibach parts on this platform: 82105.140 is the Pro-Kit lowering springs (4 springs), 82105.310 (this part) is the front anti-roll bar, 82105.312 is the rear anti-roll bar, and 82105.320 is the combined front-and-rear kit - confirm the full suffix before ordering, since these are distinct products
• Precision engineered specifically for use with Eibach Pro-Kit and Sportline lowering springs, and part of Eibach's Pro-Plus, Pro-System-Plus, Sport-Plus, and Sport-System-Plus package tiers

Features

• Further reduces body roll beyond what lowering springs alone provide
• Performance-tuned handling engineered for this specific platform
• High-tensile steel construction for durability
• Unimpaired spring comfort at bilateral spring deflection - doesn't stiffen the ride when both wheels compress together
• Decreases load difference between inside and outside wheels through a curve
• Positively influences under/over-steer handling tendency

Specifications

• Position: Front
• Bar Diameter: 25mm
• Material: High-tensile steel
• Finish: Red powder coat

Included Components

• 1x Front Anti-Roll Bar
• Mounting Hardware (application-dependent - some kits require a separate mounting kit)

Product Description

The Eibach 82105.31 is a 25mm front anti-roll bar built for the Scion FR-S, Subaru BRZ, and Toyota 86 platform, aimed at sharpening turn-in and reducing body roll beyond what a spring-only upgrade delivers. It's designed to work alongside - not replace - Eibach's Pro-Kit or Sportline springs for this platform, forming part of their larger Pro-Plus and Sport-Plus suspension packages.

Because an anti-roll bar works by resisting body roll specifically rather than stiffening the springs themselves, it sharpens cornering response without penalizing ride comfort when both wheels move together over bumps - a distinct improvement from what a spring or shock change delivers on its own.

As with the closely related part numbers on this platform, the key thing to verify before ordering is that you're getting the front-only bar and not accidentally the rear bar, the springs, or the combined front+rear kit - all of which share the same base part number but serve different roles in a full suspension upgrade.
