My Ride: 2007 530XI
ISC did revamp their front suspension from the original group buy. They started using 1 inch longer front shock and went from 10k springs to 12k springs.
I was also having issues with bottoming out in the front.
I recently purchased the new longer shock and stiffer springs from them. After doing some research and following Timmay77 post, I was looking to go to a 13.5k rated springs. ISC did not have access to this spring rate and suggested a 13k as a replacement. However the lead time would have been lengthy. I ended up with Swift 14k front springs. The ride is firm, but not overly stiff. I still need to adjust the damping to see if I can soften it up a little. I am also running the ISC rear springs and shocks.
The good news is I haven't bottomed out the front suspension since installing the new shocks and springs.

I am running ISC front and back (Group Buy) and I am switching back to Air bags and remove the spring but I need to relocate the air compressor. I like the look but I don't like the idea of deleting the Air Bag. (ride quality.) I can hear the sound from the rear spring. It is loosen, keep making noise. Hopefully switch back to air bag will work.

I put on the godspeed coilovers a month or so ago.. and I am grinning ear to ear. So far so good.. no creaks bangs or booms as mentioned in the ISC setup. I was just about to get in on it last year but was so busy trying to move/buy a different house.
I haven't really bottomed out yet with it.. drives a billion times better than my H&R spring setup. Also to note.. it rides best when on full soft.. I tried a few clicks up adjusting it twice.. and I didn't like it, it got much harder so fast that it was too bouncy feeling. I think there's like 30 clicks and I didn't even like 5 clicks.. full soft it is and I'm happy as a clam.

I've been running the ISC setup for about a year (without airbag delete). I'm pretty happy with it, though I think I'm a bit of an outlier in that I didn't want it too stiff. I spent a fair bit of time trying to tune the rebound and ended up going nearly full open. I also went a bit too low to start off and with the full M5 front end, was scraping over everything bigger than a golf ball - I measured right at 2.5 inches of clearance with the M5 belly pan. I bumped it up about 3/4 inch and have been happy with it since. Don't get me wrong - I loved it that low to start but it just wasn't practical. I have the factory software tool so I was able to drop the rear end an inch to get the stance right.

Just installed the ISC front coilovers today. Chose the 'street sport' setup. 6 clicks from total soft. It is a little bumpy, but no bottoming out yet. I *just* installed them. Rear end is stock, lowered via software. Front end is as low as it can go with the ISC setup. Will need to roll the top of the arc on the fenders as they rub a little bit, but nothing horrible. Will update with any changes.
