Rear Window Louvre (3M tape install) maximum speed?

[Arashk998]

Stupid question (and installation) but how fast would you go with rear window louvre installed using 3M tapes?
I would be comfortable driving usual motorway speeds in UK but I’m thinking more in Germany autobahns if I head that way again in the future…

would it be safer to just remove it before heading that way?

Do you mean like the MMD rear louvers ?

I never installed mine. I didn't like that I could not easily remove them to clean the windows.

Controversial I know but any modification to any car will introduce a compromise.

Good call, that and they look shit!

Hold me back....

Out of sheer luck, it started raining here on the Sunday as well.. less than 48hours after installation. Really boosts my confidence

I think the install guide says it should be dry after 48 hours, was it 3M tape for the mounts and then sealant around the edges ?

3M for everything..

Yeah but did it come with sealant, here's the install guide for mine.

Nope it didn’t, wanted this specific design so didn’t go for any ‘reputable’ brands so that’s probably why

Not sure I'd trust louvers at Autobahn speeds, especially some random sketchy brand. Louvers haven't been cool since the 80's.

I would usually agree but I feel mine blend in with the stock matte black theme.

Imma keep it real with you. My car is out here in Germany for about 3 years now, I’ve been 160+ mph (260KMH) many many times…. My rear louvres flew off around 220kmh. After about 1 year of installation. This is using alcohol wipes and cleaning the surface of the glass and using adhesion promoter. They still flew off. Thankfully it was at night so it was long gone. And nothing happened to anyone else. That is all I got to say.

Ok well that is enough of a proof to not do high speeds with it on then, thanks for sharing your experience
