BLOX Racing BXSS-50010-BK Rear Lower Control Arms Black Subaru WRX STI BRZ

Vehicle Fitment

• 2008-2025 Subaru WRX
• 2008-2021 Subaru WRX STI
• 2013-2025 Subaru BRZ
• 2013-2017 Subaru Crosstrek
• 2013-2016 Scion FR-S
• 2017-2020 Toyota 86
• 2022-2025 Toyota GR86

Fitment Notes

• Rear axle position only - replaces both rear lower control arms. Sold as a pair (2 arms included).
• Designed for vehicles that have been lowered beyond the factory camber adjustment range. On stock or near-stock ride height vehicles, OEM camber settings are typically adequate; these arms are most useful where aftermarket coilovers or springs have introduced excessive negative camber.
• OEM sway bar end links are compatible - no replacement end links required.
• Rear toe correction is not provided by this arm. If excessive toe change has occurred due to lowering, a separate rear toe link may also be needed.
• A professional wheel alignment is required after installation.

Features

• BLOX Racing rear lower control arms for the Subaru WRX/STI, BRZ, Scion FR-S, and Toyota 86/GR86 platform - a steel-constructed, direct-replacement upgrade that adds rear camber adjustability for lowered vehicles. The OEM lower control arm on these platforms provides no camber adjustment; the BLOX arms feature multiple mounting positions at the rear knuckle, shock, and sway bar end link to allow camber correction and fine-tuning beyond what the factory eccentric bolts can accommodate.
• Multiple mounting locations at the rear knuckle, shock mount, and sway bar end link provide flexible adjustment options for dialing in rear suspension geometry after lowering.
• High-quality steel construction with powder-coated black finish for durability and corrosion resistance.
• Prothane polyurethane bushings included - firmer than OEM rubber bushings for reduced deflection under lateral loads, improved rear suspension response, and longer service life under performance use.
• OEM sway bar end link compatible - no additional hardware required for the sway bar connection.
• Updated design from BLOX Racing's previous generation arm.

Product Description

The BLOX Racing BXSS-50010-BK is a pair of rear lower control arms in black powder coat for the 2008-2025 Subaru WRX, 2008-2021 WRX STI, 2013-2025 Subaru BRZ, 2013-2017 Subaru Crosstrek, 2013-2016 Scion FR-S, and 2017-2025 Toyota 86/GR86 platforms. These arms are designed to address a common issue on lowered examples of these platforms: the OEM rear lower control arm provides no camber adjustment, and aftermarket springs or coilovers often introduce negative rear camber beyond what the factory eccentric bolt system can correct.

The BLOX arms feature multiple mounting positions at the rear knuckle, shock mount, and sway bar end link attachment points, enabling camber adjustment to bring geometry back within specification after lowering. Construction is high-quality steel with a durable black powder coat finish, and Prothane polyurethane bushings are included for reduced compliance and improved rear suspension response compared to OEM rubber. OEM sway bar end links are retained without modification. A wheel alignment is required after installation. Sold as a pair. Backed by a 1-year manufacturer warranty.
