E36, E46, I don't care. That is nasty! If you're going to put a wing on that is functional, get the ACS wing. It's shhhweeet! It's the only wing I've seen that I actually like.

For a wing to generate the most down force it needs to be up in the air stream. ACS is not up in the air stream. The ACS wing produces very little down force. If you don't believe me ask ASC how much down force it produces.

The CF wing on the other hands produces big time down force in the xxx lbs range, why because it's up high in the air stream, not hidding on the deck like the ACS wing does.

This is not about what looks good or cool, this is about function. The CF wing beats the ACS wing hands down. Sorry

That may be so...but in that case, I would get custom brackets made for the ACS wing. The two vertical brackets are what restricts how high the wing will sit...I would just get longer (thus higher) brackets.

I'm sure the wing is very effective, but it's an eye sore.

At least it's being used on your car...I see Honda's everyday that have wings that size or bigger, and they don't realize that the wing is actually slowing their car down:

added coefficient of drag
added weight
they don't go fast enough to need downforce to hold them to the road

You have got to love it when a major ACS dealer (who also prepares race cars) advises against the ACS wing for the need and use I discussed with him.

The core section and width of the CF wing is 3-4 times larger than the ACS wing, a greater area to create down force.

The width and core section of the ACS is so small that even if you stuck it up high in the air stream it's not not going to create much down force, more than likly it will only create drag.

What's the amount of downforce that spoiler creates? ACS sez:
Quote:
The wind tunnel test performed by the editors at "sport auto" found that the AC Schnitzer Racing Rear Wing increased the downforce of the BMW M3 (E46) by 21.3 kg!

I hear you man, form follows function, but that wing is still ugly.

The main thing is it's doing its job. Do you have #s on the two wings that show it's added downforce/added drag?

Just curious.

I still like the styling of the ACS wing, it's a shame it doesn't apply in the real world though. Maybe something like that, just better designed? I really love the looks of that wing. As a matter of fact, that's the only wing I've seen for an E46 I would buy.

Regarding:

I read the same report and what was stated by Sport Auto was a test of the combined ACS pieces, front splitter and rear wing. The test found that the combined pieces front splitter and rear wing reduced LIFT by 21.3 kg. Nothing in the report talked about the down force created by the rear wing.

I'm just quoting what they had on their site. Weird.
