Product Details
The Riaction GT1 Coilovers for the 1987-1991 Honda Prelude BA3 deliver a premium, adjustable suspension upgrade built for drivers who want more from their Prelude BA3 than the factory setup can offer. These Honda Prelude 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. Whether you track your BA3 Prelude on weekends or log daily miles, this BA3 coilover kit dials in ride height and damping to match how you actually use the car.
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 Prelude BA3 to the height you want while preserving spring travel and shock stroke. Riaction coilovers for the 1987-1991 Honda Prelude are fully rebuildable and backed by a 2-year warranty, making the GT1 a long-term suspension investment rather than a disposable upgrade.
