Skidnation Frame Rails Chassis Reinforcementfor Mx-5 Miata NA NB

Product information

Heavy-Duty Frame Rails – Mazda MX-5 NA/NB/NBFL

A rigid chassis is key to proper suspension performance. These heavy-duty frame rails reduce longitudinal chassis flex while protecting the underside of your MX-5. With reduced flex, the suspension can work as intended, resulting in improved handling and stability over uneven surfaces. This upgrade is one of the most effective ways to increase chassis stiffness and is highly recommended for every MX-5 enthusiast.

Designed without side cut-outs and featuring bent edges, these rails maximize stiffness and strength. Unlike cheaper alternatives, no compromises were made in material thickness or design – making them among the most rigid frame rails available on the market.

Key features:

• 2 mm stainless steel construction
• Extended length for maximum coverage
• Pre-drilled for butterfly brace installation
• 3 integrated brake line brackets
• Supplied with stainless steel fixings
