Vehicle Compatibility
Designed for compatible Mazda Miata applications.
Always verify:
- Model year
- Chassis generation (NA, NB, etc.)
- Suspension configuration
before purchasing.
Why Install a Master Bushing Kit?
Instead of replacing one worn bushing at a time, a master kit refreshes nearly every major suspension pivot point.
Benefits include:
- More consistent suspension movement
- Improved chassis rigidity
- Better steering response
- Reduced suspension flex
- Improved alignment stability
- Longer-lasting performance
For older Miatas, replacing every suspension bushing at once often transforms how the car drives.
Hyper-Flex® Polyurethane Construction
Energy Suspension’s proprietary Hyper-Flex® polyurethane offers major advantages over aging rubber.
Benefits include:
- Excellent wear resistance
- High load capacity
- Reduced suspension deflection
- Resistance to permanent compression
- Long service life
Unlike factory rubber bushings, polyurethane maintains its shape and performance even under spirited driving.
Improved Handling
Replacing worn rubber bushings can noticeably improve:
- Steering response
- Cornering stability
- Braking consistency
- Suspension precision
- Tire wear
- Driver confidence
These improvements are especially noticeable during autocross, canyon driving, and track events.
Resistant to Harsh Conditions
Hyper-Flex polyurethane resists damage from:
- Oil
- Grease
- Road salt
- Ozone
- UV exposure
- Dirt
- Common automotive chemicals
This makes it an excellent long-term solution for both street-driven and performance Miatas.
Installation
Installing a master bushing kit typically involves:
- Removing suspension control arms.
- Pressing out factory rubber bushings.
- Cleaning all mounting surfaces.
- Installing the new polyurethane bushings and sleeves.
- Reassembling the suspension.
- Performing a professional wheel alignment.
Because many bushings are press-fit, installation is best suited for experienced DIYers or professional shops.
Benefits After Installation
Owners typically notice:
- Tighter steering feel
- More precise suspension movement
- Reduced chassis flex
- Better cornering stability
- Improved alignment retention
- Longer-lasting suspension performance
