Show original supplier description
The Rev9 Hyper-Street II coilover kit offers a performance-oriented suspension upgrade for enthusiasts seeking improved handling. This kit features mono-tube shocks, providing a larger capacity for gas and oil to enhance ride comfort, even when the vehicle is lowered. The internal valving allows for 32 distinct clicks of rebound force adjustment, enabling users to fine-tune the suspension from soft to stiff settings. Designed for a proper lowering, the system includes specially matched spring rates: 8 kg/mm (448 lbs/inch) for the front and 10 kg/mm (560 lbs/inch) for the rear. The full-length adjustability allows for independent control over ride height and spring preload tension. This means the vehicle can be lowered without sacrificing shock travel, which can lead to a rough ride with traditional coilovers. This kit is compatible with Honda Civic Si models from 2012 to 2013 (FG/FB chassis). It is important to note that these coilovers are a "Lowering Kit" and do not adjust to the factory ride height. Professional installation by experienced individuals is highly recommended, as no installation instructions are included.
