Power Hyper-Street II Coilover

The Rev9 Power Hyper-Street II Coilover is an entry-level suspension upgrade designed to enhance the handling performance of your vehicle. This system features mono-tube shocks, which offer a larger capacity for oil and gas, contributing to a better ride quality compared to a combination of lowering springs and stock shocks. The springs are specifically rated to improve handling performance. Key features include 32 clicks of rebound force adjustment, allowing users to fine-tune the suspension's response for comfort. The coilovers offer full length adjustment, enabling a lower ride height by twisting the lower bracket without affecting spring tension. This independent spring tension system allows for custom stiffness without altering ride height. The construction consists of full steel alloy components with aluminum hardware. The front springs have a rate of 8 kg/mm (448 lbs/inch) and the rear springs are rated at 10 kg/mm (560 lbs/inch). **Important Installation Notes:** Prior to installation, verify all hardware and properly preload the suspension to 10mm. Vehicle realignment is recommended after installation. Professional installation is strongly recommended, as these are aftermarket suspension parts and do not come with installation instructions. Rev9 Power will only warranty the item if it is installed by an ASE Certified Mechanic. **Fitment:** This kit fits BMW 3-Series (E46) RWD models from 1999-2005, including Coupe and Convertible models from 1999-2006. It specifically DOES NOT fit the M3 model.
