I think it'll make it worse due to the wraparound sections on the sides.

It won't do much with that sunroof open!

The side portion shouldn't hurt, provided it follows the existing body taper (or is slightly more tapered). Hard to tell from the pic, but it looks like it at least follows the existing lines.

it will extend the tail out a bit making a very slight angle decrease to the hatch .. doubt you'll see a big difference but looks basically like a kammback mod.. on a tamer scale.. couldn't hurt

IF the wraparound sections follow the body lines, I would say it could only help by a negligible margin.

IF the horizontal piece follows the body line, its kammback properties might be negated by the increased wetted flow area. Remember, the purpose of a kammback is to reduce the amount of drag by to eliminating surface area.

IF you want it 'cause it looks cool, GO FOR IT, 'cause it's not hurtin anything significantly

IF you're justifying the purchase by saying it'll save you gas, it will probably take like four years to pay for itself if it even helps at all

=P

IMO it looks pretty cool.

Mugen Wing

My thought is that since it's Mugen,it was built for "performance".Since it has no up-sweep it should not induce drag and my guess is that they're using it to move the low pressure wake underneath it to create a little downforce,without the drag penalty.Since it increases the fineness-ratio a tad that's also not bad.It's a perfect fit,it doesn't block your vision,could show a smidge better on fuel,I'll vote,keep it!

If you get it,don't expect terrific gains.It might get the folks next door talking about it.That wouldn't be a bad thing.Happy modding!
