R Theory NA/NB Miata V2 Rear Diffuser (1990-2005)

R Theory Motorsports' V2 rear diffuser for the NA and NB Miata, designed for track cars. It runs wheel to wheel, wider than their V1, and its curved center section keeps the air attached better than a single-angle diffuser. It also clears the muffler better than the V1.

Fits

• NA and NB Miata, 1990-2005
• The 1990-1991 and 1992-2005 kits attach to the rear subframe differently: 1992 and later subframes have a cross brace the diffuser mounts to. A 1990-1991 car fitted with a later subframe takes the 1992-2005 kit.

Specifications

• 28.43" x 49.14" x 5.21" (L x W x H)

Good to know

• The diffuser is trimmed by the owner to clear the exhaust tip, since tips vary so much.
• Made to order by R Theory once the order is placed.
