Show original supplier description
The Rev9Power Hyper-Street ONE Coilovers are engineered to enhance the performance and appearance of the 2014-2015 Honda Civic Si (FB/FG) models. This lowering kit provides a significant drop in ride height, allowing for a more aggressive stance and improved handling dynamics. Key features of the Hyper-Street ONE kit include 16 levels of adjustable damping, enabling users to fine-tune suspension stiffness for various driving conditions, from daily driving to track use. The front coilovers are equipped with pillow ball top mounts featuring camber plates, offering adjustability to optimize wheel alignment and tire contact patch. The rear of the suspension reuses the factory top mounts for a streamlined installation process. This coilover system boasts robust construction with specific spring rates: 8 kg/mm (448 lbs/inch) for the front and 10 kg/mm (560 lbs/inch) for the rear. The spring lengths are 200 mm for the front and 140 mm for the rear, with a consistent 62 mm inner diameter for both front and rear springs.
