Product Description

The TEIN Street Basis Z Coilovers (Part Number GSE20-81SS2) deliver an affordable yet refined lowering solution for Mitsubishi Lancer models from 2008 through 2017, including ES, GTS, Ralliart, and Evo trims. Featuring a twin-tube damper design with fixed damping, this kit provides smooth travel over rough surfaces while lowering your ride by approximately -55 mm front and -40 mm rear for a sporty but manageable stance.

Built with cold-formed SAE9254 steel springs and precision ZT-coated threaded adjustment sleeves, the system resists sag and corrosion for long-term durability. OEM upper mounts are retained to simplify installation and preserve factory geometry. Though damping is non-adjustable, it is tuned for daily comfort with improved cornering stability. Ideal for drivers who want improved aesthetics and handling performance without sacrificing ride quality or breaking the bank.
