The Tein Street Advance Z coilover kit is a street-oriented suspension solution for 2014 and later Lexus IS250 (GSE30L) and IS350 (GSE31L) models. It replaces factory dampers and springs with a tunable coilover system aimed at drivers seeking a tailored street ride and refined stance. Presented as a complete fitment for those Lexus applications, it supports controlled, road-focused suspension setup without added claims beyond intent.
