Why Upgrade Your NA Miata with Performance Bushings?

Factory NA Miata bushings use soft rubber compounds designed for comfort and noise isolation, which can become cracked, hardened, or excessively flexible over time. Upgrading to performance bushings reduces unwanted deflection under load, translating driver inputs more directly to the wheels for sharper handling and improved feedback.
Popular bushing modifications include:
  • Restored Handling Precision: New bushings eliminate slop and deflection for crisp, predictable cornering behavior
  • Improved Steering Feel: Reduced flex in steering rack mounts and control arms enhances road feedback and on-center feel
  • Enhanced Traction: Stiffer differential and subframe bushings minimize wheel hop and improve power delivery
  • Long-Term Durability: Polyurethane and solid mounts resist degradation better than aging factory rubber
  • Customizable Compliance: Multiple durometer (hardness) options let you balance performance and comfort
  • Track Readiness: Performance bushings withstand repeated high-load cycles without breakdown
Whether your goal is a comfortable daily driver with renewed handling, a canyon-carving enthusiast build, or a competitive track machine, the right bushing upgrades transform how your Miata communicates and performs.

Frequently Asked Questions

Do these bushings fit both NA6 and NA8 models?

Yes, the vast majority of bushing upgrades are compatible with both NA6 (1.6L) and NA8 (1.8L) models, as well as all model years from 1989-1997. The NA platform maintained consistent suspension geometry and mounting points throughout production. Always verify fitment notes for bushings that may interact with specific trim levels or aftermarket modifications.

What’s the difference between polyurethane and solid aluminum bushings?

Polyurethane bushings offer a significant improvement in precision over factory rubber while maintaining some compliance for street comfort and noise isolation. Solid aluminum bushings provide maximum rigidity and feedback but transmit more road vibration and noise—ideal for dedicated track cars but potentially harsh for daily driving. Choose based on your intended use.

Will stiffer bushings make my ride harsher?

Performance bushings do transmit more road feedback than soft factory rubber, but quality polyurethane compounds are engineered to balance precision with acceptable comfort for street use. Many enthusiasts report that the improved handling confidence outweighs the slight increase in NVH (noise, vibration, harshness). For maximum comfort, select softer durometer options.

Do I need special tools to install bushings?

Basic bushing replacement can be completed with standard hand tools, a press or bushing driver kit, and patience. Some installations benefit from a hydraulic press for removing old rubber bushings. Detailed installation guides and video tutorials are available for most kits. If uncomfortable with press work, professional installation is recommended.

Should I replace all bushings at once or focus on specific areas?

For comprehensive handling improvement, replacing all suspension bushings provides the most noticeable transformation. However, targeted upgrades (e.g., rear trailing arms for traction, front control arms for steering feel) can deliver significant benefits at lower cost. Prioritize based on your driving goals and budget.

How often should bushings be inspected or replaced?

Polyurethane bushings typically last 50,000-100,000 miles depending on driving conditions. Inspect annually for cracking, deformation, or excessive wear. Solid aluminum bushings are essentially lifetime components but should be checked for hardware loosening. Replace any bushing showing visible damage or causing handling vagueness.
