The Riaction GT1 Coilovers for the 2006-2013 Lexus IS350 RWD deliver a premium, adjustable suspension upgrade built for drivers who want more from their IS350 RWD than the factory setup can offer. These Lexus IS350 RWD 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 IS350 RWD to the height you want while preserving spring travel and shock stroke. Riaction coilovers for the 2006-2013 Lexus IS350 RWD are fully rebuildable and backed by a 2-year warranty, making the GT1 a long-term suspension investment rather than a disposable upgrade.
