Show original supplier description

The Rev 9 Hyper-Street II coilover suspension kit is engineered to enhance handling performance for enthusiasts. It utilizes mono-tube shocks, providing a larger capacity for gas and oil to improve ride comfort, especially in lowered vehicles. The system features 32 distinct clicks of rebound adjustment, allowing users to precisely tune the damping force from soft to stiff. These coilovers offer full-length adjustability, enabling independent setting of ride height and spring preload tension. This design allows for a lowered stance without sacrificing shock travel, preventing the rough ride often associated with traditional lowering springs. The spring rates are specifically chosen for performance: 10 kg/mm (560 lbs/inch) in the front and 6 kg/mm (336 lbs/inch) in the rear. Installation is recommended to be performed by experienced professionals, as no installation instructions are included, and the coilovers are designed as a lowering kit that does not adjust to factory ride height. This specific kit, R9-HS2-045, is compatible with Subaru WRX and WRX STI models from 2015-2021 (VA1/VA2 chassis).
