Why Upgrade Your NA Miata Suspension & Chassis?

The NA Miata’s lightweight, balanced chassis is legendary among driving enthusiasts, but factory suspension components can become worn, soft, or outdated over time. Strategic suspension and chassis upgrades allow you to tailor handling characteristics to your driving style while restoring or enhancing the NA’s innate agility and feedback.
Popular suspension and chassis modifications include:
  • Improved Handling Precision: Upgraded bushings and chassis braces reduce flex for sharper turn-in and more predictable cornering
  • Reduced Body Roll: Performance springs and sway bars minimize lean during spirited driving for increased confidence
  • Customizable Ride Height: Adjustable coilovers allow fine-tuning of stance and center of gravity for aesthetics or performance
  • Enhanced Feedback: Quality shocks and struts transmit road texture and grip levels more clearly to the driver
  • Track Readiness: Adjustable damping and reinforced components withstand the demands of circuit driving
  • Restored OEM Dynamics: Fresh suspension components revive the crisp, communicative handling of a new Miata
Whether your goal is a comfortable daily driver with subtle improvements, a canyon-carving street machine, or a competitive track build, the right suspension and chassis upgrades unlock your Miata’s full potential.

Premium Materials & Construction

Suspension and chassis components are manufactured using:
  • Aircraft-Grade Aluminum Alloys: Lightweight yet strong for control arms, braces, and adjustment hardware

  • Dyno-tested valving for optimized performance curves

Frequently Asked Questions

Do these suspension parts fit both NA6 and NA8 models?

Yes, the vast majority of suspension and chassis upgrades are compatible with both NA6 (1.6L) and NA8 (1.8L) models. The NA platform maintained consistent suspension geometry and mounting points throughout production (1989-1997). Always verify fitment notes for components that may interact with specific trim levels or factory options.

What’s the difference between coilovers and spring/shock combinations?

Coilovers integrate the spring and shock absorber into a single adjustable unit, allowing independent ride height and damping adjustments. Spring/shock combinations use separate components, often at a lower price point, with height determined by spring selection and damping by shock choice. Coilovers offer more tuning flexibility; spring/shock kits provide excellent value for street use.

How much lowering is recommended for street use?

For daily-driven NA Miatas, 1-1.5 inches of lowering is generally ideal. This reduces center of gravity and improves aesthetics while maintaining reasonable ride comfort and suspension travel. Aggressive lowering (>2 inches) can compromise ride quality, increase wear on components, and cause alignment challenges.

Do I need an alignment after installing suspension upgrades?

Absolutely. Any suspension modification that alters ride height, camber, or component positioning requires a professional alignment. Proper alignment ensures even tire wear, optimal handling, and safe vehicle dynamics. We recommend a performance-oriented alignment specification for upgraded suspensions.

Are polyurethane bushings worth the upgrade over rubber?

Yes, for enthusiasts seeking improved handling precision. Polyurethane bushings reduce deflection under load, translating to sharper steering response and more consistent suspension geometry. They do transmit more road noise and vibration than rubber, so consider your comfort priorities. Many kits offer multiple durometer (hardness) options to balance performance and comfort.

Is professional installation recommended?

Suspension work involves critical safety components and precise torque specifications. While experienced DIYers can install many components with proper tools and knowledge, we recommend professional installation for coilovers, alignment-critical parts, and chassis welding/modifications. Always follow manufacturer torque specs and re-check fasteners after initial use.
