On the control arms, I didn't realize they were the same material. I do know that they are non-serviceable on the S5 however. The S4 has replaceable ball-joints.
The S5 also has a larger gas tank by 2 gallons. They added a front spoiler and sideskirts on the TII. The bold items below also add weight (some due to the additional electronics to control them).

Didn't the S5 body also have some additional structural bracing added?
Also, I think there are fewer S5 models with aluminum hoods. Plus S5 spare tire jacks are heavy steel instead of the fancy German aluminum jacks of S4, and the aluminum spare tire wheel was replaced with a heavier steel one.

Former Moderator. RIP Icemark.
This has been covered quite a few times.
S5 has more add on internal structure to support the mouse belts/SRS systems.
Has more copper (wire) to support the additional engine functions and the SRS systems.
Has a bigger gas tank.
Has increased interior insulation.
Has heavier moulded carpeting.
Has heavier accessory parts (such as the S5 has a normal steel jack instead of the uberlichet German sourced jack, that the S4 models came with, and typically have the Steel spare tire rim, instead of the Enki built aluminum light weight spare found on many S4 models and the convertibles).
Has cost cutting steel engine parts (tubing, PD, Etc) instead of the light weight aluminum parts found on the S4
