Spoilers

[The real Apache]

I've taken the spoiler off the Beemer and am very happy with the cleaner look, but, will it make a difference to stability at high speed? (not that it ever gets the chance)

I was surprised to see that it did have an inverted aerofoil profile

If you are talking about the 3 series in your pic, it will have f*ck all effect. Much better without it.

Probably, nothing you'll notice at legal speeds though.

Doubt you'll notice any changes in daily use unless taken on a track or something...

Pretty much as I feel too, why put the thing on then, Alpina doesn't usually add hardware for no reason
