    DIY Removing Rip Stop from OEM Seat Belt on a NA Mazda Miata

    If you have installed an aftermarket Steering wheel, or you are planning to do so, you need to READ THIS!!!

    Thanks.

    Because the USDM NA Mazda Miata has airbags, we also have stitched part in the belts called a "rip-stop". This is an area of the seat belt which on a crash or heavy impact is designed to work WITH the OEM Airbags Safety Restraint System.
    Basically what it does is rips upon impact to slow your forward motion into the Airbag as it deploys simultaneously.

    If you keep your airbags then do nothing, you should be fine.

    HOWEVER, If you have installed a non-airbag steering wheel, AKA aftermarket steering wheel, like MOMO Sparco, Nardi, etc, and have not removed the ripstop then you will get an additional 12" inches of forward travel right into your fancy new steering wheel with your face!

    The other option is either a pair of JDM seat belts or a racing harness that is DOT approved.

    Let me be clear in saying this should be done at your own risk, and for off road use only, I, (we) the forum, its members, staff, take no responsibility for you, your passenger, or your Miata in anything you do to modify your Miata. (See Disclaimer below)

    Here you can bend this section back and look inside and see a folded up seat belt (about 12 inches worth)

    While I did not want to cut those nice looking red 93-LE seat belts, I did have a black pair from my 96 Miata that I performed this surgery on.

    (when I did the swap to red interior I installed red JDM seat belts, now sold off with that Miata)


    Look close and you can see the extra 12 inches, I was able to cut out (or release) from the rip stop with an exacto knife (this takes about 30 minutes per side)

    Again I cannot tell you to do this as a harness is much safer, however if you have not carefully cut out the rip stop and have an aftermarket steering wheel, you WILL smash your face the next time you are in a car accident.


    I hope that helps answer any questions about the USDM rip stop on the early Gen Miatas when installing an aftermarket steering wheel.

    Edit: No! NB1 and NB2 use different methodologies but neither have the folded belt that NAs do in markets that use airbags.

    Wait a second. Doesnt the NB have a completely redesigned seatbelt system? Don't they have a crush reel that under some inordinate amount of pressure bends the internals and physically locks the reels, still giving it some built in give before the actual lock?

    My understanding was if you had an nb and wanted an aftermarket wheel with no airbag, you needed to swap in an na belt and remove the extra stitching.

    Yes, and I'm browsing through these threads too fast and I should slow down when it's something this important. My apologies.

    The NB2 has the explosive pretensioner that is deployed when the airbag does. The NB1 uses a locking spool instead. Neither NB1 nor NB2 have the stitched, giveway belt that the airbag-equipped NAs do.

    If you have an NB and want to remove the airbag, buy an NA belt and remove the stitching.

    so basically it's just a portion of the seat belt that's been folded and held in place by that "sock" thing and is designed to rip upon an impact, correct? i was kinda confused on what's going on here.
