In my honest opinion, I'd say you have too high of a spring rate (front and rear), also most aftermarket add a lot of stiffness to their damper setup... my car even with softer springs (with 17% flat ride) still rides very harshly, and until I do something with the dampers, I won't get what I want. I just wish FCM was a bit more affordable.

Think it might also have to do with natural frequencies? I.e., the new suspension's natural frequencies happen to overlap more with those of underinflated stock-sized PS4Ss?

Update: This setup seems to be rather sensitive to tire pressure.
Several days ago, I noticed the car didn't feel as directionally stable as it used to. Sometimes, with no clear pattern, it felt like it was tramlining over every tiny undulation in the road. It was much worse in the rain, which was a terrifying combo with the car's subpar (IMO) hydroplaning resistance.
At some point it occurred to me that I hadn't checked tire pressures in a while, so I did that. All four tires were all a few PSI low. I pumped them all up to spec and the car feels MUCH better now.
No surprise that tire pressures count. What surprises me is how much they seem to count on my car. I don't remember tire pressure having this drastic an effect when the car was on its original suspension.

They have been cheap because of all that though and has a lot of the same issues the S65 has. The M6 is way uglier. I chose my M5 because was manual and it was cheaper than an M3 which was what I was always intending to buy. Maybe I will pick up a E92 M3 at some point too.

Shame they couldn’t justify the costs to incorporate that grav-60 construction in the rest of the lineup or future models.

Wow, TIL. The E93 is hefty hefty.
If you take the non M versions, and compare same engine, same trans, same drivetrain, body (so, say, rwd 528i 6mt sedan vs rwd 328i 6mt sedan), the e60 is only ~70 lbs heavier than the e90. BMW had to do a ton of work to get the e9X M3 to be lighter (plastic fenders, CF rood, etc), and they still only ended up ~300 lbs lighter for similarly speced cars (e90 M3 vs e60 M5).
On top of that, the hardtop vert adds a ton of weight to the e9X.

Yeah, the e60 M5 is lighter than the e93 M3, so any kit that is fine for the vert should be fine for you.

Edit: never mind I just realized Bilstein's catalog for E60 M5 cars is pretty bleak.

I thought the total power requirement would not support what I could do with a transformer, but I've never had it trip out. The Hunter Road Force balancers need air to operate the load roller also. I run that and the tire machine off a small dewalt/emglo air compressor like what you see at Home Despot, I never have them running at the same time though. Tire machines have a big tank in the column or somewhere else because it uses a dump valve to seat the beads. I chose all my stuff so that I could put it in a trailer if I wanted (and had a trailer and half ton truck for track days). It's a time or money thing. also when I said NE I meant North East or New England not Nebraska, but I guess someone told me NJ is in a mid atlantic state, certainly not New England. I'm clearly not a native.

Originally posted by hansbrix View PostFunny you say that, it's so random, since I actually I have a few Hunter RF balancers, long story. I was going to post one for sale on CL, but been busy. I never thought about posting it up here. I have a transformer setup so it runs on 125V. (they are 220V single phase machines). I also can't stand anyone else touching my car because they always eff stuff up. Rotating the tire on the rim is a major pain and I do see why they don't do that unless you pay them extra. It's almost 2x the work. Where are you? you can come check them out. I have a forklift so I load it for you no prob.
I'm in South FL so pretty far from NE state, otherwise I'd take you up on that.
