Product Details
The Riaction GT1 Coilovers for the 1998-2004 Porsche Carrera 2 deliver a premium, adjustable suspension upgrade built for drivers who want more from their Carrera 2 than the factory setup can offer. These Porsche Carrera 2 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 Carrera 2 to the height you want while preserving spring travel and shock stroke. Riaction coilovers for the 1998-2004 Porsche Carrera 2 are fully rebuildable and backed by a 2-year warranty, making the GT1 a long-term suspension investment rather than a disposable upgrade.
