It does not allow me to post pictures because of the size. Are you guys using some type of app to post? I have an android.
I usually just upload it from this app itself. You might have to make the image smaller.

I thought that could be a possibility! Sweet car btw.

I have KW HAS sitting in garage waiting on wheels.

Any feedback on ride quality / rebound greatly appreciated.
I immediately put the KW HAS was I drove it back from traveling 500 miles to pick it up. But I will say that the ride is slightly firmer than stock and there really isn't a bouncing feel.

I love this system as I had it on my M6GC also.

Thanks for the feedback; I had KW HAS on my F10 M5 and liked it very much.

Anyone with a M5C put these on yet? My concern is these may be the same spring rate as the non-Competition.. if so, you lose the additional 10% stiffness the M5C provides. Thoughts?

Can anyone comment on the installation process for these? Thought I read that the entire back seat needs to be removed to install the rear springs? Seems a bit invasive and has me a little nervous of getting some premature squeaks and rattles on a brand new car...

Do you know what the drop you set these to was in the end, in mm/inches front and rear?

It is pretty annoying but yup the full back has to be removed if you decide to lower the car so its not a quick install and will take a shop pretty much the full day to complete it if they have never done it before.

To further add, I was unfortunate where one of the connectors malfunctioned when putting everything back together. The Indy had to reach out to BMW and was told the rear seat connector had to be replaced. It took a month for that part to arrive and it didn't fix the error the car was throwing so now I am waiting for a new ACSM module which I was told would be here by month end and still nothing. So all in, I am nearly 2 months in and still have a error every time the car starts which lights up the dash and doesn't go away.

Here is my issue just in case anyone else runs into this problem. Will update once the ACSM arrives and hopefully fixes the error.

Is it the same for just a new set of springs?

(Having to remove the whole back, that is)

I would imagine so. The HAS kit is essentially a set of springs with an adjuster mechanism.

Would still love to hear more feedback from people who've already went thru with installation. Anyone have pics during install with seats removed?

G30 and F90 share the same main chassis.
I have done a few of them, only the whole rear deck and side bolsters that need to be removed. Also the seatbelt reels.

The reason being, unlike F10/F06 chassis, you can't reach the top 3 nuts holding the shock top just by removing the rear deck speakers.

Ok this is a littler better... Appreciate the info. So if I'm understanding correctly, only the rear upper deck gets removed along with side bolsters. The rear seats remain untouched. Do you have any pictures of the process? Any concerns with rattles down the road with removing all of this?

Unfortunately I don't have pictures.
If it done properly, it won't rattle.
I took my G30 apart at least 5 times already, no rattle.
So as my customers.

The problem of lowering the car's

The problem of lowering the car's attitude is that you have to change the length of the torsion bars to make them work at the right height. At the rear then with low springs we hear noises due to the misalignment of the torsion bar! But this does not tell you anybody .....
