Fits 2016-2024 Mazda MX-5 Miata and MX-5 Miata RF (Sport, Club, Grand Touring, and Anniversary editions).

Progress Technology Sport-lowering springs are engineered to significantly improve the handling and stance of the ND chassis by lowering the center of gravity and reducing body roll. These sport-tuned springs provide a more aggressive appearance while maintaining a street-friendly ride quality. While designed to work with OEM shocks, these springs offer even greater performance when paired with high-performance dampers such as Bilstein, Koni, or Tokico.

Each spring is manufactured from certified high-tensile SAE spring wire and cold-wound on precision CNC machines. To ensure maximum durability and consistent ride height, the springs are stress-relieved, pre-set, and shot-peened. A durable powder-coated finish protects against corrosion in harsh driving environments.

• Front Lowering: 1.3 inches
• Rear Lowering: 1.0 inches
• Front Spring Rate: 180 lb/in
• Rear Spring Rate: 115 lb/in
• Construction: CNC cold-wound SAE spring wire
• MPN: 40.1134

Fits 2006-2008 Mazda MX-5 Miata models including Base, Club Spec, Grand Touring, Sport, SV, and Touring.

Improve your Miata's center of gravity and handling precision with Progress Technology Sport lowering springs. These springs are engineered to reduce body roll and provide a more responsive driving experience without sacrificing ride quality. While designed to integrate seamlessly with OEM shocks, these springs are ideally suited for high-performance dampers like Bilstein, Koni, or Tokico to further refine the suspension's rebound characteristics.

Constructed for longevity, Progress specifies only certified high-tensile SAE spring wire. Each coil is cold-wound on CNC machinery, then undergoes a thorough stress-relieving, pre-setting, and shot-peening process to ensure maximum durability and consistent ride height over time. A durable powder-coated finish provides a long-lasting barrier against the elements.

The Progress Tech Rear Chassis Brace Assembly (16.0102) is engineered to reinforce the rear subframe and minimize chassis deflection during hard cornering. By providing a more rigid mounting point for the rear suspension, this brace helps maintain consistent suspension geometry and improves overall steering response and predictability for the EP3 and DC5 platforms.

• Reduces chassis flex for sharper, more predictable handling
• Reinforces high-load rear subframe mounting points
• Durable construction designed for track and spirited street use
• Direct bolt-on installation for a precise fit
• Manufacturer Part Number: 16.0102

This assembly is a vital upgrade for drivers looking to maximize the handling potential of their chassis, whether used in conjunction with upgraded sway bars or as a standalone reinforcement.
