Hyper-Street II Coilover

The Rev9 Power Hyper-Street II Coilover kit is an entry-level suspension upgrade designed to improve handling performance and allow for a custom ride height. It features mono-tube shocks with a larger capacity for oil and gas, contributing to a better ride compared to combining lowering springs with stock shocks. The coilovers offer 32 clicks of rebound force adjustment, allowing users to fine-tune their ride comfort. The full length adjustment capability allows for lowering the vehicle without negatively impacting spring tension, and independent spring tension adjustment enables custom stiffness without altering ride height. Key features include full steel alloy construction with aluminum hardware. The kit includes specific spring rates: 8 kg/mm (336 lbs/inch) for the front and 6 kg/mm (448 lbs/inch) for the rear. These coilovers are designed to fit the 1998-2005 Mazda Miata MX-5 (NB) models. **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 highly recommended as this kit does not come with instructions. Rev9 Power will only warranty the item if it is installed by an ASE Certified Mechanic.
