Does the hardtop need an adjustment by an approved Bmw dealer?

Bmw says the installation time is approx. 1 hour.
It took me less than 5 minutes to install it.






Thanks omar for the response!omar wrote:Adjustments are easy but time consuming. You'll just need a 5mm rawlplug as a guide. What you do is adjust the locking pins that go into the car up and down with the aim of getting a 5mm gap between the roof and the body behind the side window. After that it should be fine tuning though I never got mine to stay totally quiet above 80mph until I added some draught proofing foam tape to the front edge of the roof and the deformations in the windscreen rubber seal caused by the soft top over time. There's a BMW tech bulletin on this somewhere.
Just to be clear, Increasing the gap I mention tilts the roof forward to eliminate the gap at the windscreen. Good luck!
It definitely tranforms the car. Actually it is a matter of taste. Personally, I decided to buy a hardtop because I wanted a quieter cabin when travelling. But basen on my current situation, it is proved that it is even worse.Paulj100 wrote:I had a simulier problem when I bought my hard top there would be wind coming in from the front edge above the window screen but was simple fix for me just pressed hard down on the hardtop front edge and it dropped about 1-2mm then made sure it was locked down from inside, cured all the wind noise instantly. Love the hardtop transforms the Z
Hope you get it sorted.

Where are you based? Easy to do but hard to explain.derin100 wrote: ↑Sat Feb 09, 2019 9:30 pm So, just resurrecting this thread as I've just put the hardtop on my Z4M today and driven it with it on for the first time ever. I too have noticed this symptom with wind noise at the leading edge on the driver's side.
I understand the principles of the described adjustment above i.e. adjusting the back edge of the hardtop makes the front edge press down harder on the top edge of the screen. But I don't know exactly what I have to adjust and how hard is it to do?
Thanks

Happy to show you if you’re near Sheffield? Or I can make you a video tomorrow if no one explains it well tonight.
