Much harder/taut, it literally feels like an M5. The soft isolated glide is gone and it feels like a BMW so if you like that great if not you may not want the 500 series

Hope you dont mind another question.
I have never tried a M5 myself. My wife used to have a 2001 IS300. I always thought that was the perfect combination. Very fun to drive around town. But still not to harsh for a log trip. Curious if you have ever tried the IS yourself and how it would compare.
Thanks

Why not test drive an M5? If you can find one, that'll tell you.

Yes, that is what I was going to still try and do. But BMW dealer about an hour away from me. Before I read this post, I had always told myself that I would just keep buying air shocks when needed. Only have 47K miles and is my garage car or toy. Plan on keeping it a long time.
My wife gets car sick from the boat feeling on anything but the sport mode. So I thought I would have to keep air shocks. Since I expected coil overs to be more like normal mode.
I myself also like more of sports car ride vs soft luxury.
So a bit excited reading this post. That I could do away with the problems of having air shocks. And not only have a sport mode ride but even better. For me it would be great to go one step more than my oem sport mode. More like the IS ride but in the LS size. And I would also get the remote controller which would be neat. I figure I was also be saving so much over the years on any air shock problems it could still be cheaper.
Even if I have only had one replaced so far which was under warranty.

I COULD be wrong, but I'm pretty sure that price is for all four corners. I can't see why they would ask for the spring rates for both front and back on the same purchase unless it included both front band back shocks. And comparing that prices to other options I've looked it, $1900 for all four is a little higher than some competitors but still reasonable. IE - the BC Racing shocks are $1245 for all four. But if it rides like an M5 and keeps the ride height, I'd be happy to pay a little more. I'm giving the 500s strong consideration.

I think the price is for all four corners too, and I am also considering these.

The pricing is def for all (4).

I contacted them a couple months ago when I was at crossroads on whether to go coil overs, or get new OEM air struts.

FYI when I contacted them in August, wait time was 6-8 weeks minimum.

@XF40FSPORT What did you end up going with? If coilovers, what did you go with and how do you like them?

I kept the air suspension & added a Data System controller.

I finally just ordered a set of Mullers from Fortune. Had them increase the shock length by 20mm and increase the rear spring rate so I'll have 12kg front and 10kg rear. I live in the mountains so this will give me a bit more stiffness. I can adjust the shocks down to stock height or up to 0.7" above. Now if my wife will let me but some All Terrains on it... I'll post when I get them in and installed.

OK! - Got my Mullers in from Fortune Suspension. These things have 5.75" range in height. Since I live in the mountains and I'm not looking to lower (and springs sag over time), I had them add 20mm of height to them, It was free. I also went with spring rates of 12k / 8k front/back. I'll let you guys know how they are. I'm going to start tearing out the rear seats now.
