Spec Miata Donor Cars for Sale

What makes a good Spec Miata donor

• 1990–1997 Mazda Miata (NA, 1.6L and 1.8L)

  Any NA Miata. 1.6 and 1.8 cars race together, balanced by weight and restrictor plate.

• 1999–2005 Mazda Miata (NB, 1.8L)

  Any NB except the 2004–05 Mazdaspeed turbo. A rust-free manual car with a clean title makes the best donor.

Cars are matched by year, make and model. Check the current rulebook before you buy, since trim, engine and transmission details can matter.

Build or buy?

A finished race car almost always costs less than the parts, labor and safety gear that went into it, so building makes the most sense when you want to know every bolt, already have the tools, or can do the cage and wiring yourself. If the gap above is small, a used Spec Miata is usually the better deal. See Spec Miata race cars for sale.
