SPL rear adjustable swaybar endlinks for the Toyota GR Corolla feature massive PTFE-lined FK 1/2" bearings to provide the highest load capacity for use with stiffer aftermarket sway bars. Additionally, SPL endlinks improve rear sway bar response and increase its effectiveness (rate) by replacing the OEM rubber bushing end with a spherical. Custom heat-treated chromoly high-misalignment studs allow for extreme articulation angles (up to 65°) to prevent endlink bind when used with adjustable sway bars.Unlike OEM, SPL endlinks are adjustable, enabling you to eliminate unwanted preload on the sway bars, set the ideal bar angle, and, if equipped with ride-height adjustable coilovers, properly corner balance your car. The result is better handling, more sway bar tuning options, and less variation in performance between right-hand and left-hand turns. Even stock cars can take advantage of this upgrade by simply dialing out the swaybar preload that occurs when you sit in the car to drive it.
