at ''normal'' speed, it won't really give you downforce.
That being said, i like the look it gives and i would keep it too.

I disagree about spoilers being ineffective under 200mph. I'm no aero engineer, but i did work for a friend's racing team and was taught a lot about downforce. A e39 M5 lip spoiler, for those who know what that looks like, can generate 35-50 lbs of downforce at under 100mph. And that thing is tiny.
As for mods, i dont know. I told myself i wouldn't, but i said the same thing with my 328. I've got other priorities first, namely doing the s54 bearing recall (M roadsters & coupes never got an official recall because of their lower redline, bmw said they weren't affected), but i'll do it just to be sure. (And then raise the redline:P)
Other than that, maybe a stebro exhuast, i'm on the fence as to if i want it louder.
I have 3X as much money in my e36 as i do in this car (mostly mods), and in terms of driving experience, there's absolutely no comparison between the two cars.

Can you show me in writing that the rear lip on a E39M5 give 35-50 lbs of downforce? That is a fact I didn't know about my car.

Buzzed hornet, i'll try to find what was shown to me. I think it was bmw's own wind tunnel testing.
It shouldn't be hard to calculate ourselves, i think the formula for downforce is (0.5)(Area of wing)(aero coefficient of wing)(air density) (speed^2)
I have a m5 lip spoiler on my e36, so i could measure the area roughly, but i dont have the aero coefficient of the wing. I'd be curious to confirm that aswell, as it does seem like a high number for such a small wing. The M wing on the roadie definately creates more downforce than that (weight = downforce, aero aside
)
Complain more about the fitment of the hood! That's a much bigger issue, and i'm totally considering not fixing it this summer!
Always a joker, huh dana? I hope you & your family are doing well!
