Christmas Bundle: Stainless Differential Cups + Polyurethane Bushings

Get the most out of your MX-5’s rear differential with this exclusive Differential Reinforcement Bundle, combining two essential upgrades for enhanced performance and longevity:

MX-5 Stainless Differential Mount Stop Plates

Replace the rust-prone stock washers with our lightweight, rustproof stainless steel mount cups plates. These are designed for use with polyurethane bushings but can also work with OEM rubber bushings when paired with our optional circle bushings. Protect your differential from wear and tear while ensuring long-term reliability.

Key Features:
– Made from high-grade stainless steel for rustproof durability.
– Compatible with polyurethane or OEM bushings (with option “new bushings – yes”).
– Includes an optional set of stainless steel fixings (4x M8 + 2x M12 nuts).
– Fits all MX-5 NA, NB, and NBFL models (1989–2005).

MX-5 Polyurethane Differential Bushings

Upgrade your MX-5’s rear differential with polyurethane bushings for improved throttle response, better shifting, and reduced axle hop. Available in two stiffness options to suit your driving style:

Performance Street (80 ShA): Stiffer than OEM, but still comfortable with improved precision and durability.
Race Track (90 ShA): Hard bushings for track-focused builds and enhanced performance.

Kit Includes:
– 1x set of rear differential polyurethane bushings.
– 1x grease pack for installation.

Shipping options: worldwide.
