2023-2026 Toyota GR Corolla

The SPL Parts SPL RUA E210 Rear Upper Camber & Caster Arms are precision-engineered suspension components designed specifically for the 2023+ Toyota GR Corolla. Built for enthusiasts who demand maximum adjustability and on-track performance, these arms replace the factory rear upper control arms to provide independent camber and caster tuning capability — critical for dialing in alignment on lowered or track-prepped GR Corollas. Whether you're chasing lap times or setting up your car for aggressive street driving, these arms deliver the adjustability and durability that SPL Parts is globally recognized for.

Key Features & Benefits

• Independent Camber & Caster Adjustment — Dual-axis adjustability allows you to tune camber and caster separately, giving you precise control over handling balance and tire contact patch without compromise.
• Billet 6061-T6 Aluminum Construction — Aerospace-grade aluminum arms are lightweight yet extraordinarily strong, reducing unsprung weight for improved suspension response and handling dynamics.
• High-Misalignment Spherical Bearings — SPL's signature spherical bearing ends eliminate compliance and deflection found in rubber bushings, providing direct, consistent feedback and improved cornering precision.
• Anodized Finish — Hard anodized surface treatment offers excellent corrosion resistance and durability in all weather and track environments.
• GR Corolla-Specific Engineering — Designed from the ground up for the E210-platform GR Corolla, ensuring proper geometry correction when lowered or running aggressive alignment settings.
• Track-Proven Design — SPL Parts components are trusted by professional motorsport teams and amateur racers worldwide, bringing race-level engineering to your GR Corolla build.
• Eliminates Alignment Limitations — Factory arms limit alignment adjustability; these arms unlock alignment ranges required for performance driving and suspension tuning.
