For lowered cars, track builds, or anyone dialing in alignment more seriously, these arms provide a large camber adjustment range to help optimize tire wear, grip, braking stability, and handling balance.\u003c\/p\u003e\n\n  \u003cp\u003eUnlike factory rubber-bushed arms, SPL rear upper camber arms use high-quality spherical bearings and a motorsport-focused double adjuster design. The outboard, clamp-style adjuster is easier to reach on the car and does not use traditional jam nuts, making camber changes cleaner, faster, and more repeatable.\u003c\/p\u003e\n\n  \u003ch3\u003eKey Features\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLarge Camber Adjustment Range:\u003c\/strong\u003e Allows precise rear camber setup for street, track, and lowered applications.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEliminates Bushing Deflection:\u003c\/strong\u003e Improves rear suspension response and consistency under load.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSharper On-Limit Feel:\u003c\/strong\u003e Helps the rear of the car feel more predictable during aggressive cornering.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOn-Car Adjustment:\u003c\/strong\u003e Outboard double adjuster is easier to access near the knuckle.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNo Jam Nuts:\u003c\/strong\u003e Clamp-style adjuster design helps prevent wandering alignment specs during adjustment.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAdvanced Setup Potential:\u003c\/strong\u003e Can be used with adjustable lower arms to make small kinematic changes and fine-tune bump geometry.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePTFE-Lined FK Bearings:\u003c\/strong\u003e Self-cleaning, US-made spherical bearings for precision and durability.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDaily to Race Use:\u003c\/strong\u003e Suitable for everything from street-driven GR Corollas to dedicated track cars.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eWhy We Like It\u003c\/h3\u003e\n  \u003cp\u003eRear camber control is a big deal on a performance car like the GR Corolla, especially once the car is lowered or pushed harder on track.
