Description

The STI front coil spring provides a 15 mm reduction in vehicle height to improve the handling dynamics and aesthetic of the Subaru BRZ (ZC6) and Toyota 86 (ZN6). Each purchase includes a single spring, and you must purchase two units to complete a full front set. Installation on non-compatible models or vehicles with incorrect strut setups may upset the intended front-to-rear chassis balance. Vehicle height reduction may vary slightly based on installed optional accessories and natural variances in individual vehicle bodies. This product is not compatible with RA (RWD/6MT), RA Racing (RWD/6MT), or STI Sport vehicles. Please verify your specific trim level before purchase. Because these parts are sourced for JDM specifications, we recommend consulting with your local authorized dealership to confirm compatibility for your specific region and vehicle configuration.

MIA's Description

The STI front coil spring is a performance suspension component designed to lower the vehicle ride height by 15 mm compared to the OEM spring. This spring is intended for use with standard front struts to enhance driving stability and reduce body roll for a sportier stance.

Please note that this package includes a single spring; two units are required to complete a front set. Compatibility is specific to certain Subaru BRZ and Toyota 86 models.
