Maruha Pro Spec Coilovers with Mazdaspeed bushing for 1990–2005 Mazda Miata MX-5 (NA/NB)
Upgrade your Mazda Miata’s handling with the premium Maruha Pro Spec Coilover Kit, engineered by Maruha Motors Japan and custom-built by Buddy Club Japan. Designed specifically for the NA and NB generations (1990–2005), this high-performance suspension system delivers razor-sharp steering precision and unmatched track day reliability without compromising daily street usability.
Key Performance Benefits
Track-Ready Alignment & Feel: Equipped with pillow ball upper mounts to provide rigid, direct feedback and crisp cornering response over traditional rubber bushings.
The Strategic Choice for Drivers: While MazdaSpeed reinforced bushings achieve a stiff rubber durometer hardness of 70 degrees for a direct response, drivers who are concerned about the harsh impact absorption of solid pillow upper mounts will find the tuned Maruha assembly to be the absolute optimal middle ground for direct handling and real-world street compliance.
Eliminate Bottoming Out: Features a custom 20mm extended rear upper mount that preserves essential damper travel, removing harsh rebound and bump-stop crashing even at lower ride heights.
Independent Ride Height Adjustment: Full height adjustment is handled entirely through the bottom bracket sleeve, letting you slam or corner-balance your Miata without altering spring preload or compromising shock stroke.
Advanced Technical Specifications
Massive Piston Diameter: Features a 46.0mm damper piston—the largest piston bore profile available on the market for the Miata chassis.
15-Step Adjustable Damping: Easily tune your compression and rebound settings simultaneously using the top click adjusters to match track conditions or street comfort.
Optimized Spring Rates: Tuned base setup featuring 8.0 kg/mm Front and 6.0 kg/mm Rear springs for optimal balance.
Low Friction Finish: Coated in an off-black internal bore plating designed for maximum thermal dissipation and smooth friction-free travel.
Fully Rebuildable Architecture: The fully overhaul-capable (O/H) design means the absorber cartridges can be replaced or serviced individually for lifelong durability.
