Product Description

The Tein VSC76-C1SA3-C Flex Z is a complete coilover kit for the 2006-2011 Lexus GS S190 platform, covering the GS300, GS350, GS430, and GS450h in RWD configuration. With 560 lbs/in front and 448 lbs/in rear spring rates, 16-way damping adjustment, and full-length ride height adjustability, this kit transforms the GS's luxury-sport balance - delivering a sharper, more planted feel without compromising the composure that makes the S190 one of the most rewarding large RWD sedans of its era.

Built in Yokohama, Japan with twin-tube construction and Tein's sealed damper structure, the Flex Z provides long-term performance at an accessible price. Note that inner fender clearance should be checked during installation, as individual vehicle differences may require minor trimming. AWD GS variants are not compatible. Professional installation and wheel alignment are recommended after fitment.
