ISR Performance Pro Series Coilovers - MAZDA MIATA MX5 89-05

The ISR Performance Pro Series Coilovers are the top-tier suspension upgrade for the 1989-2005 Mazda Miata MX-5 (NA and NB chassis). 32-way adjustable damping, mono-tube design, 8K front and 6K rear spring rates, and front pillowball upper mounts. Built with Japanese bearings for the kind of damping consistency and longevity that the Street Series can't match.

What It Does

Pro Series coilovers step up from the Street Series with adjustable damping (32 clicks of compression and rebound adjustment), mono-tube damper design (better heat dissipation and damping consistency vs twin-tube), pillowball upper mounts on the front (more direct steering feel and stiffer top-of-strut connection), and Japanese-sourced internal bearings. The 8K front / 6K rear spring rate is firm enough for serious track and autocross duty while still being livable on the street, and the rates are tuned for the Miata's light front weight and balanced chassis.

Adjustable Ride Height and Damping

Threaded bodies let you set ride height anywhere from mild to slammed. The 32-way damping adjustment lets you run softer on the street and stiffer at the track, which is exactly the use case the Pro Series is built for.
