installed new CF mirrors.

[sojusoulja]

Well, i got around to installing my Mracing mirrors. Same ones used on ASm S2000 and others i believe.
Took about three hours to install.

These are just preliminary pics.

 

[TURBO2GO]

Looks good. They are tiny. Can you see well with them? How much were they?

 

[NeoNSX]

I think we need some close-up photos taken outdoors.

 

[KSXNSX]

What are you going to do with the holes in your doors?

 

[sojusoulja]

I'm planning on doing a photoshoot soon probably after Hot Import Nights so I'll have better shots of the mirrors.

As for the holes I just covered it up with some carbon fiber. Temporary fix...well permanent unless I decide to have the holes filled and door repainted.

So, I take it benefit is less drag; but how much? (I'm serious..:redface: )

 

[NSXrebel]

I've been thinking of changing my mirrors to something like this. I have a W_I_D_E convex rearview mirror, wide enough that I could do without sideview mirrors if they weren't mandatory. I can look at the rearview mirror and see clearly both sides of the car. So if I lost some visibility with these mirrors, I can make up for that.

Can you show us a pic of the CF you used to cover up the holes? I was thinking of using some sort of decal as a temp fix, if I were to go through with this mod.

Interesting question! As far as I can tell, the exterior rearview mirrors are responsible for about 3.2% of an NSX's total aerodynamic drag.

I couldn't find any drag coefficients for rearview mirrors but the drag coefficient of a hollow semi-sphere that has the curved portion facing into the wind is 0.38 according to aerodyn.org. NSX rear-view mirrors are shaped pretty much like hollow semi-spheres, so that drag coefficient should be a decent approximation. If I measured correctly, each rear-view mirror has a frontal area of about 0.0239 m2 (239 square centimeters). Both rear-view mirrors together therefore create a total drag (Cd*A) of about 0.018. A stock pop-up headlight NSX has a drag coefficient of 0.32 and a frontal area of 1.78 m2, so a total drag (Cd*A) of 0.57.

Therefore about 0.018 of the total 0.57 drag of the car is caused by the rearview mirrors, or 3.2%.

I am curious since I actually like the shape of the OEM mirrors. Is there a CF kit or a CF mirror set that is the same style as the OEM?

 

[sojusoulja]

visibility with these is pretty good.
the mirror has a slight blueish tint and is convex.

they cost $330 shipped.

as for weight savings I can quote the S2000 specs. The stock S2k mirrors were 2.XX lbs. per mirror. The CF mirror only weighs 0.4 lbs./mirror.

Well, the CF I used was supplied from the seller. It is a thin sheet with sticky backing. I traced the base of the OEM mirror onto the CF and just cut with scissors. However, it doesn't work too well. The dorr has curvature and over time the CF just unsticks.

I am going to try using some Black vinyl. Besides, I think the black vinyl will blend in better and not attract attention to the problem area like CF does.

Very nice!!

Where can I order a set of these for my NSX?

procars has a CF oem shaped mirror replacement.

Thanks for the detailed analysis! hmm... that's interesting. Sounds like I need to replace my mirrors :tongue:

Interesting mod, I actually like the look of the oem mirrors on the nsx, also, what will you do about ice?

I take it these do not have heat elements installed?

I live in California...ice isn't a problem over here:biggrin:


I always thought the NSX oem mirrors made the car look dated. I've been wanting to change them out for a while now.

Hmmm... if you completely remove the rearview mirrors and thereby decrease the car's drag by 3.2%, the top speed should increase by about 1.05%. For a stock car, that should be a gain of about 1.75 mph.

Replacing the stock mirrors with Mracing mirrors will eat up a bit of that potential gain again, but you will still have a lower wind resistance than stock, a higher top speed, and you can be rid of the OEM mirrors. I've also always thought the OEM mirrors look a bit clunky compared to those on some other sports cars.

Here is my rearview mirror some of you were asking about. It would compensate any visibility lost with these smaller cf mirrors. I've gotten so used to it, now when I drive any other car with a regular mirror, it feels strange to me.

You have a rear-view mirror? I've deleted mine for weight savings and because it blocks my visbility looking AHEAD.

Given a 5% dark tint all around, I just bob my head back and forth multiple time before I make lane changes now :biggrin: Seems kind of scary but you get used to it. The real test is in the dark, that's when you learn to "drive by faith, not by sight" :tongue:

Wow...that thing is huge. I put an after market auto-dim/compass one in my car and it's only slightly larger than the stock one...and it gets in my field of view when I'm driving a little more than I'd like.

I would have a serious blind spot in the front with that thing...

 

[NSXrebel]

lol, you get used to it. and as for the blind spot in front, it's not that bad. It does make me feel a little safer since I have a wide view of the rear. No one is gonna surprise me by sneaking up on me (carjackers).

I'm hoping I can fix this problem with some sort of FI.

Can you post a closeup pic of the mirrors and the mounting base?
I found a seller on S2ki that sells a similar mirror but he does not know if it will fit onto the base on our NSX.
APR Formula 3 Mirrors - Carbon Fiber

Is this the same mirror?

Thanks,
