Product Description

The SPL RTA IS300 adjustable rear toe arms from SPL Parts are designed to upgrade the rear suspension of the Lexus IS300 (2001-2005) by replacing the factory rear toe arms with precision-machined adjustable units. By incorporating high-tolerance rod ends and an adjustable length design with a rotating clamp to lock your setting, this kit helps maintain correct rear toe geometry under lowering, wide-tyre or high-load applications - ideal for track or high-performance street builds.

Installation involves removing the OEM rear toe arms, installing the SPL units, setting your desired alignment (especially important if the vehicle has been lowered or fitted with aftermarket suspension), and then locking the settings using the clamp system. A full rear alignment is strongly recommended post-installation to maximise the benefits. Fitment is confirmed through model year 2005; fitment for later Lexus IS models (e.g., IS250/IS350) or other chassis is **unconfirmed** at time of listing.
