Which mirror has better aero

[canadian_yeti]

Haven't posted in a couple years, but I have a new mpg focused project. Its a 2003 s10 that I will be focusing
heavily on aero mods. Wondering which mirror would have better aero.

First is a 94-05 "street scene" knock off style sport mirror.
Second is a BMW M3(E36) style mirror made to fit an s10

Why not peep mirrors?

They're available in 3" and 4" sizes. A pair of 3" mirrors for $41.00 on eBay. They're available with built-in turn signal repeaters.

The A-pillar is a problematic area aerodynamically. The door top is closer to the driver's eye.

I have a 1998 S10, and people are always walking into the mirrors.

I assume these idiots are accustomed to knocking into mirrors that fold back.

Just saying, a mirror that is cheap and easily replaced or that folds back may be the more economical choice in the long run.

From the mirrors shown the first one, the long narrow one of simple design is what I would favor.

I say this with the major blind spot most pickup trucks have in mind and the necessity for a convex mirror. The long narrow mirror with a convex glued on to the outer most mirror region should work. However, if you can get the entire mirror surface in convex that would be preferred because the smaller the mirror the more useless it becomes (unless convex).

Also if you are doing an aerodynamic bed cover that has no back window, these side mirrors will be your only connection to the outside world adjacent and behind you. Make them as effective as possible.

I think the peep mirrors would certainly suit a look I have in mind, but I figured the complete flat surface would be less aerodynamic compared to either of the 2 I posted.

As for a cover, I plan to do a type of kammbak off the cab and a partial tonneau cover. Not quite as good as an aeroshell, but I'll be doing 99% highway driving so I'll need the visibility.

We're kind of crippled by the database errors, but there have been posts on the subject. The peep mirror could have a bollet-shaped nose added. More subtle would be a ring-shaped wickerbill. And they can be positioned half-way back on the door, for better aerodynamics and visibility.

Ask kach22i: ecomodder.com/forum/showthread.php/roof-spoiler-pick-up-truck-cab-phase-1

There exists a comparison chart I can't quote at the moment -- a cab-top Bonneville spoiler and half-tonneau is close to the aerocap in performance. Plus you get a closed compartment behind the tailgate.

I have looked at that post recently. Showed a graph on aero mods represented as a percentage of CD drop. Top 3 were roof spoiler and partial cover, aero shell, and full body redesign. Doing the spoiler/partial cover option for budget, simplicity, and appearance.

There ya go. For the lurkers bots.



Basic Redesign has none of the features.

What kind of look?

[kach22i]

I was just looking up mirrors and found this - sorry for the sidetrack but might be of use?
