PCI Rear Upper Camber Arm Set

PCI Rear Upper Camber Arm Set - Toyota GR86 / Subaru BRZ (2022+)

Zero-Deflection Geometry & Precision Camber Tuning

Take total control of your rear suspension geometry with the PCI Rear Upper Camber Arm Set. From the factory, the GR86 and BRZ offer zero rear camber adjustment; when you lower the car, the camber naturally moves into a negative range that can't be corrected. PCI solves this with a robust, adjustable upper arm designed for the rigors of competitive motorsport. Unlike many aftermarket options that use rubber or polyurethane bushings, PCI utilizes high-quality spherical bearings to eliminate "bushing bind" and deflection, ensuring your alignment remains constant even under the highest cornering loads.

What’s Included in the Box:

- Pair of Rear Upper Camber Arms: Left and Right assemblies.

- Spherical Bearings: Pre-installed high-misalignment racing bearings.

- Stainless Steel Spacers: Precision-machined for a perfect fit into factory subframe mounts.

 -Grade 8 Hardware: High-strength fasteners for the adjustment turnbuckles.

The PCI Advantage

- Total Camber Adjustability: Features a heavy-duty turnbuckle system that allows for fine-tuned camber adjustments without having to remove the arm from the vehicle. This is essential for correcting "camber gain" on lowered cars or adding negative camber for track performance.

- Spherical Bearing Technology: PCI is world-renowned for their bearing housings. By replacing the compliant factory rubber with spherical bearings, you eliminate the "vague" feeling in the rear end and stop the suspension from "wiggling" during high-speed transitions.

- 6061-T6 Billet Aluminum: CNC-machined from aerospace-grade aluminum for a massive increase in strength and rigidity over the OEM stamped steel arms, all while maintaining a lightweight profile.

- Increased Chassis Clearance: The arms feature an offset, slim-profile design to provide maximum clearance for the frame and axles, which is critical for vehicles running extreme low ride heights or long-travel suspension setups.

- Hard Anodized Finish: Finished in a signature matte black hard anodizing for superior corrosion resistance and a long-lasting "race-spec" aesthetic.

- Made in the USA: Designed, machined, and assembled in Southern California.

Precision Tip: Most owners choose to adjust camber via the lower control arm, but adjusting from the upper arm is often preferred by professional racers. Adjusting the upper arm helps maintain better axle geometry and keeps the roll center more stable on extremely lowered cars. Because these utilize spherical bearings, you will notice more mechanical "feedback" from the rear suspension—it’s the sound of precision.
