Power Hyper-Street II Coilover Kit

The Rev9 Power Hyper-Street II Coilover kit is an entry-level suspension upgrade designed to enhance the handling and aesthetics of select Mini Cooper models. This system features mono-tube shocks, which offer a larger capacity for oil and gas compared to twin-tube designs, leading to improved ride quality and performance. The coilovers provide 32 distinct clicks of rebound adjustment, allowing enthusiasts to precisely tune the suspension to their preferences and driving conditions. Installation involves full-length adjustability, enabling users to lower the vehicle by adjusting the lower bracket rather than preloading the spring. This method helps maintain optimal spring performance. The kit includes front springs rated at 8 kg/mm (448 lbs/inch) and rear springs at 7 kg/mm (392 lbs/inch), chosen to complement the handling improvements. Construction consists of full steel alloy components with aluminum hardware for durability. **Important Installation and Warranty Information:** Prior to installation, it is crucial to verify all hardware and properly preload the suspension to 10mm. Vehicle realignment is strongly recommended after installation. Due to the specialized nature of aftermarket suspension components and the absence of included instructions, professional installation is highly recommended. Rev9 Power will only honor the warranty if the item is installed by an ASE Certified Mechanic. This product also carries a California Proposition 65 warning regarding nickel content.
