Mazda MX-5 NA / NB Subframe Reinforcement Arms (Frog Arms)

Chassis reinforcement arms for Mazda MX-5 NA and NB, which significantly increase body stiffness and improve steering response.

Frog arms reduce chassis deformation under load, leading to more precise vehicle handling and better steering feel. The result is more stable vehicle behavior, especially during dynamic driving or track use.

Components are made from high-strength steel tubing and laser-cut steel plates, which are then CNC formed and professionally welded.

Installation is simple and requires no welding – only basic tools and drilling mounting holes are needed.

The surface treatment with powder coating in graphite color ensures high corrosion resistance.
