1989-2005 Mazda Miata MX-5 NA6/NA8/NB1/NB2
Q1: What exact models and years do these Miata coilovers fit?
A1: These coilover shock absorbers are specifically engineered to perfectly fit the 1989-2005 Mazda Miata MX-5. This comprehensive fitment covers the entire first-generation (NA6, NA8) and second-generation (NB1, NB2) chassis, ensuring a direct bolt-on suspension upgrade.
Q2: How much can I lower my Mazda Miata MX-5 with this kit?
A2: You can easily achieve a much more aggressive stance with an adjustable lowering range of 2 to 4 inches below factory ride height. This drastically lowers your car's center of gravity, which improves both aerodynamic aesthetics and high-speed stability.
Q3: What are the spring rates on these 1989-2005 Miata coilovers?
A3: This Flashark setup features custom-tuned spring rates of 7 kg/mm (392 lbs/in) in the front and 6 kg/mm (336 lbs/in) in the rear. These high-tensile performance springs have been heavily stress-tested over 600,000 times to guarantee less than 0.04% distortion, giving you long-lasting performance.
Q4: Are these MX-5 coilovers too stiff for daily street driving?
A4: Not at all. They are highly recommended for daily driving. Thanks to the twin-tube shock structure and premium rubber top mounts, these struts effectively absorb hard impacts and road imperfections, delivering a smooth and forgiving ride for comfortable city use.
Q5: Will lowering my car ruin my suspension travel and damper stroke?
A5: No, it will not. A major engineering advantage of this coilover kit is the independent ride height adjustment. You adjust the height by threading the lower shock mount—not by compressing the spring. This guarantees that you maintain full damper stroke and maximum ride comfort, no matter how low you set the height.
Q6: What materials are used to construct these shock absorbers?
A6: To ensure maximum durability while shedding unsprung weight, vital components like the mounts, locking collars, and spring perches are CNC-machined from 6061-T6 Billet Aluminum. This aerospace-grade material makes the kit exceptionally strong and highly resistant to rust.
Q7: Do I need to purchase additional tools to adjust the ride height?
A7: No extra purchases are necessary. Every 4PCS Flashark coilover kit includes the required stainless steel spanner wrenches, allowing you to easily adjust your ride height and securely lock the collars in place during or after installation.
Q8: What is the proper spring preload setting for this Miata suspension kit?
A8: For optimal shock performance and to eliminate any unwanted spring clunking noises, we highly recommend setting the spring preload between 7-10 mm during installation. This keeps the spring properly seated when the suspension is completely uncompressed.
Q9: Are these shock absorbers rebuildable if they eventually wear out?
A9: Yes, these twin-tube shock absorbers are fully rebuildable. This feature significantly extends the operational lifespan of your suspension investment, making them one of the most cost-effective and sustainable upgrades for your NA or NB Mazda Miata.
Q10: How will this upgrade affect my Miata's body roll in corners?
A10: By replacing aged, soft factory struts with these performance coilovers, you will experience a dramatic reduction in body roll. The stiffer 7k/6k spring rates and precision valving prevent excessive nose-dive under hard braking and keep the chassis flat and predictable during spirited cornering.
Q11: Will this suspension kit fit both the 1.6L and 1.8L engine configurations?
A11: Absolutely. The suspension mounting geometry on the 1989-2005 Mazda Miata MX-5 remains identical across the NA and NB generations, regardless of whether your vehicle is equipped with the 1.6L or 1.8L engine block.
Q12: Why does this kit use rubber top mounts instead of pillow ball mounts?
A12: Rubber top mounts are intentionally integrated into this specific kit to maximize street comfort. While rigid pillow ball mounts are excellent for track-only race cars, they transmit excessive harshness and noise into the cabin. The rubber joints effectively isolate NVH (noise, vibration, and harshness), resulting in a much quieter, high-quality street driving experience.
