OVERVIEW

Achieve precise rear alignment control and drastically cut unsprung weight on your 2022+ Toyota GR86 or Subaru BRZ (ZN8/ZD8) with the Racer X Fabrication Tubular Rear Upper Control Arms. Designed as the ultimate rear camber adjustment solution, these control arms feature a re-engineered pivot location that allows for wide camber adjustments while minimizing unwanted toe changes during suspension travel.

Constructed from ultra-strong 4130 chromoly steel tubing (far surpassing standard A513 DOM tubing in tensile strength and fatigue resistance), these arms shed a massive 4 lbs per arm—delivering 8 lbs of total unsprung weight savings across the rear axle. Heavy-duty polyurethane inner bushings with zinc-plated steel inserts eliminate unwanted suspension deflection under cornering loads, while race-grade outer rod ends and custom CNC-machined studs ensure unyielding reliability. Each set is finished in a durable satin black powder coat for maximum corrosion protection.

FEATURES

• 4130 Chromoly Tubular Construction: Crafted from high-strength 4130 chromoly tubing for maximum structural rigidity and long-term durability under extreme track conditions.
• Massive 8 lbs Unsprung Weight Savings: Reduces total vehicle weight by 4 lbs per arm compared to heavy factory stamped steel upper arms.
• Optimized Kinematics & Camber Range: Re-engineered geometry minimizes toe change during camber adjustments to keep alignment setup fast and predictable.
• Low-Deflection Polyurethane Bushings: Includes stiff polyurethane bushings with zinc-plated steel sleeves to maintain alignment settings under hard cornering.
