Lets talk side mirrors!

Every .05 adds up.

Similar principal to doing every little mod that gives 1-2kw Eventually you accumulate quite a few ponies.

I bet you'd gain no more than .05 second around a 2:00 track.

in other words, you'd never notice the difference.

those are pretty cheap for dtm style mirrors. but i think they look weird on e30s.

Yes, they are very cheap. Cheap enough for me to order a set to check out.. I'd like to use a set of those on my track car. They don't look quite right, but the aerodynamic increase over the barn-door mirrors is undeniable at the speeds my car is capable of [when running]..

i'd be really surprised if there was a significant weight saving. maybe 1 lb or so. but 5-7 lbs? no way. aerodynamically, sure - the E30 mirrors are wide and flat.

I was thinking the same exact thing. The heaviest part of the mirror is the glass, and that will remain (but maybe just a smaller piece).

Our car's are bricks. You don't need numbers to back it up. Take your hand, push it through the water perpendicular to your palm, then parallel. What flows better? Parallel. Water is just a denser version of air (they're both fluids.)

Id like to see some pictures of those on e30s

sir im going to say your past post was null in void for the pure fact that every rx8 driver here has a giant tampon up their ass. im writing RX8's off all together

null in void?

must be a new phrase im not familiar with.

Nice find.. I can't believe those didn't pop up when I searched!?

[speedblind]

These look like they'd help

Sure they can and do.

Bit expensive, but very high quality with minimal distortion.

Longacre is much cheaper, but has distortion and distance perception issues at first. Although it does serve the purpose of letting you see that something is behind you.

I use the longacre 17" and do not look at my side mirrory anymore. You can see Bpillar to Bpillar easily. I can see the front of cars that are driving next to my door.

It's easy to mount to a 'normal' plastic mirror, just drill a couple holes.

Personally, I don´t think the rearview mirror can replace the side mirrors, particularly in order to eliminate blind spots. How wide/curved should it be in order to do that? But I might be wrong. I got my side mirrors really well adjusted so there are no blind spots and therefore no need to turn your head to watch for incoming traffic. Anyways, my scale is not exactly accurate (it´s just a bath scale, not even digital), but according to it, the stock power mirror weighs around 2lbs., (each one) and these aftermarket units (powered also) about 1.5lb each. You can see in the pics how the shapes are really different, apparently the aftermarket ones should put a lot less resistance, although that wasn´t the reason to buy them. I won´t be hitting 100+mph anytime soon unless I fall off a cliff.:P

They make mirror delete plates. Or just use some pieces of plastic and cut/bolt to fit. With a wide rear view you don't really use the side mirrors anyway.

[speedblind]

Removing the mirrrors or folding them in is probably the easiest solution. As someone else mentioned, you're saving wind resitane, not weight. The resistance caused by the mirrors can be significant.

And coefficient of drag is just that - a coefficient. It takes into consideration the entire frontal area of the car. Drag is the force created by air swiring around the back of the car - it essentially pulls it backwards. So cD isn't a great measure of how "aerodynamic" a car is - most people when talking aerodynamics are thinking about resistance. In that respect, our cars absolutely are bricks.

Also, most race cars have horrible Cd. I think F1 cars are like 1.0 or larger. Obviously, there's a reason for it.

[E30Nova]

I have ALWAYS been curious about how mirrors like these would look on an E30.

Never seen those on an E30 but I've seen them on a lot of jap cars like Skylines and such.

I think they'd look better than those fugly ass DTM mirrors and ACS mirrors. Those things look absolutely retarded.

i dont drive a volvo?

Check out the cd of older Volvos, you might be surprised..
