*  Data source TireRack.com; values are adjusted to reflect representative rolling radius.  Manual calculation results may differ, using equation [63360/(πΦ)], where Φ is the tire’s unloaded diameter (inches), since Revolutions per mile of a mounted tire under load will generally be about 3% more than the calculated number.  These are most likely the numbers programmed into the PCM, for converting ABS wheel revolution data into Vehicle Speed.

Recommended Tire Pressure (B-pillar placard states 29 PSI for both front & rear tires on all models, however, upon closer analysis of that placard):

Normal loading (cargo + occupants 340 lbs.): 32 – 36 PSI (cold) vs. stated 29 PSI
High-speed driving (> 75 mph): 32 – 36 PSI (cold)

Recommended Tire Fitment Max Sizes (with stock wheels):

225/45R17 or 225/45R16 (for stock vehicle height)
215/45R17 or 225/45R16 (if vehicle lowered ≈ 1″)

✅ Upgrading both interior light bulbs with Super-bright CANbus LED units* is highly recommended for significantly improved lighting

 Note: LED “bulb” substitutions can be made for incandescent bulbs, but they won’t always behave well with the Body Control Module (which interprets the very small circuit current draw as a burned-out bulb, resulting in “hyperflash”), unless: (1) at least one of the bulbs in the respective circuit remains incandescent, or (2) the LED bulbs are CANbus “error-free” units (built-in load resistor), or (3) you splice into the wiring circuit to add your own inline resistor.

  1. Hi, I am going to change oil in both differential and MT . I d like to have beforehands the Drain plug crush washers for the plugs .. By reading the specs posted they look to be 18mm ID/25mm OD but the link sends to a Washer Gaskets For Mazda Part# 9956-41-400 that if I am not wrong looks to be 14 mm internal diameter. Where do I misunderstand ?

    • Good catch Claudio! I’m surprised no one has said anything before. The link was from a Mazda forum reader, but I believe you are correct. I’m going to change the link to https://amzn.to/2qLVcpe , that appear to be not only cheaper, but better suited to the job as well. Please let me know how whatever you end up with, works out 😉

  2. Based on feedback from @HaZ & @Good-Win Racing, I’ve added to the Wheel & Tires Specs:

    Recommended Tire Fitment Max Sizes:

    225/45R17 (for stock vehicle height)
    215/45R17 (if vehicle lowered ≈ 1″)

    Had also added Specs for Fiat’s “Historical” wheel a few days ago, as well.

  3. [EDITED 11/25/2019]
    John M. pointed out nice alternatives to the factory side-repeater lights with removable bulb and either smoked lens or clear lens. I added to the Lights section.

    It’s also been pointed out that with some force, you can remove these lights (and the factory version) from the exterior by design:

    I just pushed the light rearward (with some force to deflect the large spring tab) & it allowed me to pull the front out & away.

    which is especially nice if the [optional Mopar] splash guards have been installed with rivets, making the fender guards difficult to be pulled aside for behind-the-panel access. [Be advised that the movement of the lamp could mar the body panel paint finish though.]

    • Hi Dan,
      sorry, but I have to disagree with that. Replaced my side repeaters with these ( https://www.zymexx.de/produkt/led-seitenblinker-fuer-mazda-mx-5-nd-rf-fiat-124-spider-und-124-abarth/ ) a few months ago.
      Opening a gap in the fender guards is actually pretty easy. They are held in place with rivets similar to the ones used on various interior panels.
      Turn the steering wheel to full lock and remove the lowermost 4 rivets. That should give you enough space to fiddle your arm in and reach the clip holding the repeater. Takes about 5 minutes per side.

      Some people on the Miata board warn about the remove-from-outside methods. Some have managed to scratch their paint cause quite a bit of dirt accumulates behind the repeaters.

  4. Added a footnote for Wheel Revs per Mile stats:

    * Data source TireRack.com; values are adjusted to reflect representative rolling radius. Manual calculation results may differ, using equation [63360/(πΦ)], where Φ is the tire’s unloaded diameter (inches), since Revolutions per mile of a mounted tire under load will generally be about 3% more than the calculated number. These are most likely the numbers programmed into the PCM, for converting ABS wheel revolution data into Vehicle Speed
