Product Details
The Riaction GT1 Coilovers for the 2010-2013 Mazda 3 deliver a premium, adjustable suspension upgrade built for drivers who want more from their 3 than the factory setup can offer. These Mazda 3 coilovers are engineered to pair street comfort with canyon and track capability, giving you the stance, handling, and adjustability you've been chasing without compromising daily driveability.
Every GT1 set features a monotube damper with 32 levels of damping adjustment, so you can tune ride quality to match the road, the weather, or your driving mood. Full-length ride-height adjustment separates preload from ride height — meaning you can drop the 3 to the height you want while preserving spring travel and shock stroke. Riaction coilovers for the 2010-2013 Mazda 3 are fully rebuildable and backed by a 2-year warranty, making the GT1 a long-term suspension investment rather than a disposable upgrade.
