RX1 Coilover System with H.B.S.

The Tein RX1 Coilovers offer advanced suspension performance for the 2015-2021 Subaru WRX and WRX STI. These coilovers incorporate Tein's "Hydraulic Bump Stopper (H.B.S.)" technology, which has been proven in motorsports like the WRC and ERC. This system effectively generates damping force near full-bump to absorb large impacts smoothly, preventing jarring jolts and maintaining controllability when a vehicle is lowered. Key features include adjustable front camber, allowing for precise alignment tuning. The damping force can be adjusted across 16 stages, providing a wide range of customization for different driving conditions. Ride height is adjustable from 1mm to -88mm in the front and 19mm to -81mm in the rear, with included front and rear springs rated at 8 kgF/mm and 7 kgF/mm, respectively. The coilovers are also compatible with the Tein EDFC system for on-the-fly damping adjustments. Construction includes OEM specification brake hose fittings, anti-corrosion coating, and dust boots for durability. Installation notes indicate that for the rear, interior components may need to be removed, modified, or relocated to avoid interference with the motor. Exceeding the recommended ride height adjustable range may lead to clearance or interference issues and could void the product warranty. The front suspension allows for -1.2 to -3.5 degrees of camber adjustment, with a ride height adjustment range of -3.5 to 0.0 inches. The rear suspension offers -1.0 degrees of adjustment with a range of -3.2 to 0.7 inches.
