Product Description

The TEIN GSW02-91AS3 Street Advance Z Coilovers are a sport-oriented suspension upgrade designed for 2019 through 2025 Mazda Mazda3 models - including sedan, 5-door hatchback, and fastback body styles in both front-wheel drive and all-wheel drive configurations. This complete coilover kit replaces the factory struts and springs with adjustable components that let the driver dial in both ride height and damping to achieve the desired balance of comfort and performance.

Unlike basic lowering springs, this kit features 16-way damping force adjustment on both front and rear dampers, allowing fine-tuning of compression and rebound feel to match daily driving, spirited canyon runs, or light track days. The threaded spring seats let you lower your Mazda3 aggressively while the corrosion-resistant ZT Coating and powder-coated bodies improve long-term durability even on wet or salty roads. Compatible with TEIN's optional EDFC system, these coilovers provide a customizable ride without sacrificing everyday drivability.
