Mazda MX-5 NA/NB Coilovers – 1 Way

Thunderlane coilovers for the Mazda MX-5 NA and NB are built to order, with spring rates and damper valving selected specifically for your car.

Rather than using one generic setup across both generations, each kit is configured around the chassis, vehicle weight, intended ride height, tyre choice, modifications and how the car will be used.

This is particularly important on lightweight NA and NB builds, where excessive spring rate or poorly controlled damping can quickly reduce grip and make the car nervous over uneven surfaces.

Key Features

Custom spring rates and damper valving
Selected to suit your NA or NB’s weight, tyres, modifications and intended use, rather than relying on a universal off-the-shelf specification.

20-way rebound adjustment
Allows you to fine-tune the response, balance and body control of the car without adding unnecessary adjustment complexity.

Application-specific damper setup
The dampers are configured to control roll, pitch and weight transfer while preserving mechanical grip and compliance.

Microcellular polyurethane bump stops
Provide controlled, progressive support near the end of the suspension travel, helping prevent harsh bottoming and supporting the car during high-load compression events.

Electroplated damper bodies
Help protect the damper bodies against corrosion and harsh road conditions.

Fully rebuildable construction
The dampers can be serviced, repaired and revalved rather than replaced as complete units.

Individually dyno tested
Every damper is tested and validated before dispatch to confirm that it performs consistently with the intended specification.

Specified Around Your Car

Before the kit is built, we will ask for information about your MX-5, including:

• NA or NB chassis
• Intended road, track or competition use
• Vehicle weight and modifications
• Wheel and tyre setup
• Intended ride height
• Aero or weight-reduction modifications
• Driver preferences

This allows the spring and damper package to be developed around the complete car rather than supplying the same fixed setup for every application.

Additional Options

• Swift spring upgrade
• Alternative spring rates
• Linear or digressive valving
• Road, track or competition specification
• Custom setup consultation
• Revalving and servicing support

Thunderlane Mazda MX5 NA and NB coilovers are designed to improve control and confidence while preserving the responsiveness and mechanical grip of the lightweight chassis.
