Mein Auto: E70 XS SAV
There is a sports suspension on the E70

I know this is an old thread, but there are separate part numbers for the dampers. I can't find the spring part numbers, but typically BMW does not change dampening without a need (higher spring rate), and each configuration has a different bump stop, so it's likely the springs have different rates. The following is for the 3.0 only, not the diesel or the 8 cylinder vehicles. I ran into a brick wall at the dealer when trying to find out specifics about the myriad of suspension options available. I do know the swaybars are the same on all packages unless you get the Adaptive Drive. The inserts for that set up are completely different and include the EDC module and associated hardware.

-- Edit- looks like the S226A is only available outside the US, oh well.

I personally preferred the 19" all seasons with the sports package, but ride quality and handling are subjective, and need to swap tires come winter as well as road quality are individual factors (obviously depending on where you live). What you desire from the vehicle comes into play as well.

I also have not had an X5 before, my previous BMWs have been an E30 M3, E36 M3, E36 MC SC, and an E46 328. These are very very different animals, so perhaps my expectations of the SAV are not the same as someone else.

For Reference, the E70 6 cylinder suspension strut insert numbers are as follows.

Front (same L/R)-
Standard 31326781917
W/sport suspension (S226A) 31326781919

Rear (gets really involved, as there are many options)
Standard 33526781921/922
Sport (S226A) 33526781927/928
Self Level + 3rd Row (S220A + S4UBA) 33526781925/926
Self Level + Sport (S220A + S226A) 33526781877/878
Self Level + Sport + 3rd Row (S220A + S226A + S4UBA) 33526781931/932

If anyone could find out about springs that would be great, I'd love to know if they have different rates or if indeed it is just a change in the inserts compression/rebound settings.
