This spec doesn't apply to the car you selected.
Not yet checked against the factory manual for your car's year. It's verified in the 2005 Mazda MX-5 Miata Workshop Manual (electronic manual capture); later manuals may differ.
60.0–72.0 mm
Factory manualTaken from a Mazda factory workshop manual, with page citation.
Procedure
Install the MT PPF bracket, remove the transmission jack, then measure vertical A from the illustrated underbody reference plane to the lower PPF surface using the factory reference surfaces. Adjust PPF position if outside specification. This dimension is not ground clearance. Erroneous printed inch endpoint is retained only in the citation.
Applies to
- NB 2001–2005 (BP-Z3, 6MT) — Other years in this family inferred from 2005 factory evidence with owner approval; actual-year verification is separate.
- NB 2004–2005 (BP-Z3-TURBO, 6MT) — 2004 family applicability inferred from the generic 2005 differential procedure with owner approval.
