For those that have PDCC fo you disable it when on track? Should I throw in the towel and just go Ohlins?

 

Great question — and a common one for those running PDCC (Porsche Dynamic Chassis Control) on track.

🏁 Short Answer:

No, most drivers do not disable PDCC on track. In fact, many find it beneficial — especially in high-speed corners and transitions — due to the reduced body roll and enhanced stability it provides.

🔍 More Detail:

Pros of keeping PDCC ON during track use:

• Reduces body roll, keeping the car flatter in corners, which helps with weight transfer and predictability.
  
• Improves cornering stability, especially in quick transitions like esses or chicanes.
  
• Maximizes tire contact patch, particularly in heavier cars like the Turbo or Panamera.
  

Potential downside:

• Some advanced drivers say PDCC can mask chassis feedback slightly, especially under extreme loads or in slower, technical sections.
  
• Slight artificial feel in transitions for drivers used to fully mechanical setups.
  

✅ Best Practice:

• Try a session or two with it ON, and focus on what the car is telling you.
  
• If your car allows disabling PDCC via PASM settings or with a controller (Cobb, CarPlay-based interface, etc.), try back-to-back comparisons if you're experienced and curious — but most find it's better left on, particularly on tracks with high-speed sweepers or elevation change (like Road America or COTA).
  

If you're running aftermarket sway bars or very aggressive suspension setups, that’s where disabling PDCC might make more sense — but for most, PDCC is an asset, not a liability.

 

If you're even thinking about Ohlins, you're probably already at the point where the stock suspension is holding you back — especially on a 991.1 Turbo S. Here's a breakdown to help you decide if it’s time to make the leap:

🔧 Ohlins vs Stock 991.1 Turbo S Suspension

✅ Ohlins (e.g., Road & Track or TTX):

• Customizable damping & rebound (dual- or single-adjustable depending on spec)
  
• Significantly better feedback & body control on track
  
• Height adjustable, so you can fine-tune rake, corner balance, etc.
  
• Lighter weight than OEM PASM dampers
  
• Improves tire wear and heat control with better weight transfer management
  
• Can be spec’d with spring rates suited to your tire choice & use case (e.g., Cup2 vs AD09 vs slicks)
  
• Highly rebuildable and tunable over time
  

🚫 Downsides:

• No PASM integration, so you lose in-cabin adjustability
  
• More NVH (especially if spring rates or damping isn’t street-optimized)
  
• Initial setup matters a lot — corner balance, alignment, preload, damping all need proper tuning or it won’t feel “right”
  
• Can be overkill for pure street use unless you’re okay with a firmer ride
  

🆚 Stock PASM Setup (with PDCC):

• Very competent for a dual-purpose street car — plush when needed, decent control in Sport/Sport Plus
  
• Integrates with drive modes, active damping is quick to react
  
• Tuned to balance comfort and grip for OEM tire sizes and geometry
  
• Works well on mild track setups or fast canyon carving
  
• Not bad until you're pushing >8/10ths regularly or running 200TW or R-compounds and seeing IAT/brake/roll limitations
  

💭 Consider This:

If you’re doing:

• 5+ HPDEs a year
  
• Running sticky tires (AD09s, CR-S, Cup 2 R, etc.)
  
• Getting annoyed by body movement, pitch/dive, or traction loss on mid-corner bumps
  
• Already upgraded sway bars, bushings, camber plates, etc.
  

→ Then yes, go Ohlins. It’s transformative — especially on the Turbo, which is inherently heavy and rewards chassis control.

🛠️ Recommendation:

• Ohlins R&T if you're 60% street / 40% track
  
• Ohlins TTX or similar motorsport setup if you're 70%+ track-focused
  
• Pair with adjustable camber plates (Tarett or similar) and a solid alignment for best results
  
• If you're not ready to lose PASM, consider Bilstein Clubsport (still firm, but retains some PASM integration in 991.1)
  

 

I've learned to leave mine on, per advice from an advanced instructor at my last event. He used to have a 996 TT that he'd track, and gave me a lot of good insight on how to make this platform go even faster, one of which is leaving PDCC on. My 'local' track is pretty bumpy and I definitely found that having a softer ride improved control and lap times. I probably could turn it off on a smoother, grand prix track like COTA, but I'll test that theory at the next event which I believe is in November this year.

 

I just read that the Bilstein Clubsports arent compatable with PDCC. (?)
