Miata 1.8 Differential Carrier Reinforcement (Torsen and Open)

This is a service, not a part you bolt on. You ship me the differential carrier from your 1.8 NA or NB Miata (the carrier only, not the whole diff), and I weld reinforcement plates onto it and ship it back. It works on both Torsen and open carriers. If you place an order without realizing you need to ship in your carrier, there's a 20% cancellation fee.

The standard option is what almost everyone needs. It reinforces the passenger side arm where the factory notch is, which is the setup shown in the product photo. The both sides option adds the same reinforcement on the driver side. That's mostly cosmetic, but I'm happy to do it.

If you need me to supply a carrier, reach out and I'll see if I can find a core for a fee.

Turnaround is about one week once your carrier arrives.
