The NSX-R OEM Momo Tuner steering wheel.
It has red stiches so I think it’s for the NA1 Type-R but it’s the same Momo wheel for the NA2 NSX-R with black stiches.






I quite like the red stiches with the contrast to the black leather.
Overlaying against my NSX-R steering wheel.
Some owners prefer the black horn button from Type-S but I think it’s no longer available.

At the back of the wheel, you will find several information. As they are owners specific info, I erased them from this photo but the owner can see the original photo.



The tyre pressure was way too low.
Probably it was adjusted when the weather was still warm.
It only had about 1.8kg at the front and 2.3kg at the rear.
For now, pumped it up to OEM 2.3/2.8 setting but considering the tyre used, probably better suits with bit lower setting.

Time for the test driving session before detailed Health Check.

    For the driver side (SRS device used to be part of the original steering wheel), yes, there will be no more SRS and thus, please check your local regulation and insurance for this.
    The passenger one (if you have one) stays the same and will be activated when the condition met.

    This is the reason why I strongly recommend using the OEM Momo steering boss when installing the non-SRS wheel.
    It has self-crushable mechanism to protect the driver in case of huge impact and it also uses extra fixing screws to fit the steering wheel that you don’t get ‘wobbly’ feeling that can be felt on some of the aftermarket wheel installation.
    In Japan, the combination of OEM NSX-R steering wheel and the OEM boss are recognised by some of the insurance companies.

    Hmm well that settles it for me no new steering wheel. Its bad enough that the wife thinks the car "unsafe" as she has no airbag. Suggested she brings a pillow and bites on it!

    For the clarification, removing the SRS steering wheel won’t affect the passenger side SRS (if your NSX has one).

    For your reference, SRS is a ‘Supplement’ system and only effective if the seat belt was worn properly.
    If you have a chance to visit the automotive crash test or watch its video, you will understand this.

    Even at less than 10mph, if you hit rock solid non-movable object, you will feel enormous impact.
    There is a simulator that you can safely experience this.
    Your body can move in different angle and the seat belt will do good job in holding your body.
    Your injury could be reduced by the seat belt and the SRS or by the crushable OEM boss upto certain speed but the brain will be under serious stress at much lower speed.

    Unlike your body held by the seat belt, the brain can’t hold itself and will hit the internal wall of your skull even at low speed.
    So, you want to remind yourself that SRS is a supplement device for the seat belt and if you want to protect your brain and body, keep defensive driving from other potential dangers and know your limit. Most of the time, the driver's ability will hit the limit first than the chassis side.

    Also, when installing any additional switches, lever, etc around the steering wheel, please keep them behind the wheel and not on it.
    Same concept as the FIA technical regulation for the Formula racing. You can find it on their website.
