H.Tech Lowering Springs

The Tein H.Tech Spring Kit is engineered to transform the driving experience of the 2003-2008 Toyota Corolla ZZE130L FF models. This premium spring kit aims to enhance both performance and comfort, providing a superior ride quality. The kit utilizes the latest spring and material technology, designed and tested in North America for use with OEM or similar shocks. Constructed from durable, lightweight Vanadium (SAE9254V) steel with a gold powder coat finish, these springs are built to withstand daily driving while maintaining their performance. The progressive spring rate design is optimized for comfort and handling, offering a slight drop in ride height for improved aesthetics and aerodynamics. Front spring rates are 2.3 kgf/mm (129 lbs/in) with a recommended ride height reduction of -44mm (-1.7 inches), while rear rates are 2.7 kgf/mm (151 lbs/in) with a recommended reduction of -46mm (-1.8 inches). The kit includes silencer rubber on certain applications and comes with a one-year limited warranty covering defects and sag over 5mm, but excludes powder coat finish and rusting.
