The Sparco seat base is a vehicle-specific mounting plate for the left side of Lexus IS250 and IS350 models from 2006 onward (Australian fit noted). It supplies a side-specific foundation for a replacement or aftermarket seat and calls out the regional fit variant, helping shoppers match the correct left-side base for these Lexus models and their regional configurations.
