I was convinced I needed air spring and I used the crap out of them on my e53 but when I switched to e70 two years ago I accidentally bought one with coil springs. It will sag pretty good when I over load it but even with 6-700# of tools in the bag (not overloaded), I don't even notice the sag and what I do notice is it's a much more comfortable ride.

I used to think people were crazy to do an air spring delete but if you don't regularly haul ≥ 1000# of crap I think you can be very happy with the softer ride.
