Porsche 991 GTS Control Arm Wheel Hub Front Rear Shock Absorber
For the Porsche 911 GTS (991 generation), the suspension and hub components are a mix of Carrera S parts and track-oriented hardware. Because the GTS features a lower ride height (PASM Sport) and a wider track, these components are precision-matched.
1. Control Arms (Wishbones)
The 991 GTS uses a reinforced lower control arm (often called a “coffin arm”).

2. Wheel Hubs & Bearings

3. Front & Rear Shock Absorbers (PASM)
As established, the GTS uses PASM-specific dampers.
-
Front Strut (PASM GTS):
991-343-035-48.-

The “DSC” Upgrade: In 2026, many GTS owners install a DSC Sport V3 Controller ($1,450) instead of replacing shocks. It plugs into the factory harness and optimizes the existing dampers for better ride quality and track grip.

5. Critical Installation Note: The GTS Center Lock
If your GTS has Center Lock hubs, you must not apply anti-seize to the wheel mating surface, only to the threads and cone of the nut itself (using Optimoly TA).

-
Hub Life: Porsche recommends replacing Center Lock hubs every $6,000\text{–}12,000\text{ track miles}$ or $60,000\text{ street miles}$ due to the extreme stress on the single locking mechanism.
