Miata Differential Mount for PPF Delete - NA and NB

NA8 (1994-1997) bracket option is now available!

This is a bolt-in solution for securing the front of a 94-05 Miata 1.8 diff with the PPF (power plant frame) removed on an NA or NB Miata. No fabrication is needed like other options on the market. And unlike most homebrew solutions, our setup also incorporates a 88A poly bushing to help reduce vibration and noise. This is the perfect mount to pair with our Getrag 260 5-speed and ZF 6-speed transmission upgrade kits.

The lower subframe brace is made of steel bar, powdercoated black, and the upper mount is machined out of 6061 aluminum. All necessary hardware is supplied. The aluminum mount is machined so the poly bushing sits at a 1.5 degree angle, which provides OEM driveline geometry.

This front differential mount must be paired with upgraded rear differential bushings made of polyurethane or Delrin. 

Additionally, if you plan to launch the car hard in a drag racing or autocross setting, we recommend reinforcing the right differential arm, as Mazda designed this part to crack in an impact. Miata diff arms have been reinforced for years with weld-on aluminum plates. We now offer the first bolt-in solution with our differential arm reinforcement plates. Add Energy poly rear bushings and reinforcement plates to your order and receive discounted package pricing. 

Note that two lower mounting brackets are now available (NB bracket is pictured). The NA8 bracket is for 1994-1997 cars, and the NB bracket is for 1999-2005 cars. 

Sorry, 1990-1993 owners will need to swap the rear subframe to a newer version since the 1.6L cars did come come with any attachment points for a rear subframe brace.

All NA and NB subframes mount to the chassis at the same points and have the same suspension geometry, so swapping rear subframes is straightforward, especially with the differential already removed from the vehicle.
