found it ish, Next, mirror drag is quantified at 3-6% of total vehicle drag for a modern car in a report called Contribution of different devices to the total drag (PDF):
"A very well designed mirror increases the drag of a car of approximately ΔCd=0.012. But this value can reach 0.025 to 0.030 for the worth [worst] designs. Actually it seems reasonable to think that the average value for ΔCd is of around 0.015" |

are we really arguing over the fuckin drag co-efficient of a CAR MIRROR?

Here's a picture:
If the US Air Force felt like it was okay to put a rear view mirror on the U2, the presence or absence of a mirror is going to make fuck-all difference on your car. |

Wow. You know it doesn't matter what you are discussing on the internet, everyone always has to be ****s.
1 - EVERY car manufacturer on the planet is working on replacing mirrors with cameras. The hold up is with archaic rules in the DOT. The same rules that are holding up active LED and laser headlights. The fact that major manufacturers have already developed these systems pretty much invalidates every one of the "dumbest idea ever" posts. 2 - my phone has a 1080p display and can record 1080p video. the components are off the shelf at this point. In terms of hardware required, this could be done for the same amount of money as a set of high end aftermarket mirrors. 3 - you guys will discuss cat deletes all day for a gain of ONE horsepower, but reducing the drag of the car by 3-5% is "not worth the time" and "illegal". If aero is so insignificant, why did Toyota bother with putting under body panels on to smooth airflow under the car? I'm not sure if I have ever seen a forum so full of trolls. Good to know that a community is so unsupportive and stagnant that they are unable to answer a simple question of "have you ever seen an off the shelf system that would work?". A simple "no" would have sufficed. |

And extrashaky: the U2 had a pair of turbine engines generating 38,000lbs of thrust and it flew at 70,000ft where the air is less than 5% the density that it is at sea level. out of all of the troll posts, this was the one that was the least relevant.

What's funny is this car is about being each to their own. I'm sure there were probably people who thought the same thing when I kept pushing the heated mirror issue on US spec FR-S and what it would take to add them since it was clearly established up to that point FR-S didn't come with them here.
Well guess what. We found you could add it on a 10 Series buy adding the mirror housings and plugging in the correct relay for a total plug and play and through the efforts of @Silent_Dan doing it on his base model FR-S we've found you can just add the pins to the door harness (both ends) and splice wiring between the pins you add because we also tracked down the Toyota Wire Harness repair manual which list all the part numbers to order the repair pins with a section of wire pre-crimped which more or less makes it plug and play as well other than having to run the extra bit of wire. So kudo's to this guy/gal who wants to do something unique. Good luck. |

A couple of things.
I was going to troll you and you sincerely deserve it; this is ridiculous, but I see those positions are already filled. Even though the amount the mirrors are dragging is likely as much as the front license plate and a really insignificant thing to focus so much effort on, I'll help because I claim to see no basis for being able to dictate to others what they can do with their own cars. This is me walking my talk. Snarking system deactivate. Sarcasm cannons do not lock target. TRD claims that these split the air effectively and allow the mirrors to slide through that slot more smoothly. You don't have to engineer anything, just buy em and bolt them on. I'm actually looking at picking up a set myself, for that reason secondly, firstly for aesthetic reasons. I think the trim at that spot now looks stupid. http://www.trdparts.jp/english/86_pe...line/aero.html

How fast do some of you guys drive where the mirrors drag is even a measurable impact on speed or mileage?
I have factory mud flaps, drive with my windows open and frequently have my arm out the window. Does this mean I am sucking up gas and going way slower than I should be? This is not a formula one car we are talking about here and some things can be taken too far for the results that are gained. Gonna head over to the Prius room where they really know their stuff on this topic and see how many thousands of dollars I can spend to save .002 mpg.
