Height-Adjustable Springs for the Porsche 911 (991/992): Lower It, Keep PASM
Height-Adjustable Springs for the Porsche 911 (991/992): Lower It, Keep PASM
If you want height-adjustable springs for the Porsche 911 (991 and 992) that lower the stance without giving up factory ride quality or PASM, the TL-HAS height-adjustable spring kit is built for exactly that. It is a spring kit — not a coilover — that keeps your factory dampers, so PASM electronic damping and the car's driver aids stay fully active. Priced at $1,200, hand-assembled in Poland and built to order, it lowers and corner-balances the 911 while leaving the parts of the car you actually like alone.
Why height-adjustable springs make sense on a 991/992
The modern 911 leaves the factory riding a little tall, but its adaptive PASM dampers are genuinely good. That creates a dilemma: full coilovers give you stance and adjustability, but you throw away the factory adaptive damping and often the driver aids that depend on it. Simple lowering springs fix the stance but give you a fixed drop and no way to corner-balance.
The TL-HAS threads the needle. You keep the factory PASM dampers — so the electronic damping and driver aids stay active exactly as Porsche intended — while gaining an adjustable, threaded ride height and the ability to corner-balance the car. You lower the 911 and improve its stance and centre of gravity without trading away the ride quality and adaptability that make a 991/992 so usable every day.
What the TL-HAS does
Keeps PASM and the factory dampers
Because the TL-HAS is a spring kit that retains your OEM struts and dampers, PASM's adaptive damping keeps working — Normal and Sport modes, and the driver aids tied to the suspension, all stay live. No coding, no defeated warning lights from removing the adaptive dampers, no giving up the compliance you paid for.
Adjustable, independent front and rear height
The kit offers front lowering of 15–35mm and rear lowering of 20–40mm, with front and rear adjusted independently. That range lets you choose a subtle drop that just tidies the arch gap, or a more aggressive stance, and it lets you set rake to taste. Independent adjustment is also what makes proper corner-balancing possible — setting equal cross weights so the car handles evenly left to right.

Ride height, and street vs track
For a street 991/992, the appeal is obvious: dial in a clean, level stance with usable ground clearance, close up the wheel gap, and keep the adaptive ride you love for daily driving and road trips. For a car that also sees track days, corner-balancing on the TL-HAS sharpens handling balance while PASM Sport still manages damping. It is worth being clear about the ceiling: because you keep the factory dampers, damping itself is not separately adjustable the way it is on a full coilover. If you are chasing maximum track adjustability — independent rebound and compression tuning — full coilover options exist for owners going further. For the large group of 911 owners who want a lower, better-balanced car that still rides and behaves like a factory Porsche, the TL-HAS is the smarter tool. Browse the range in the TL-HAS collection.
Fitment
The TL-HAS is built for the Porsche 911 991 and 992 generations in both 2WD and 4WD, including the Carrera S 2WD. Because it is built to order, confirm your exact model, generation and drivetrain when you order so the kit is matched to your car. See related applications in the Porsche collection.
FAQ
Will I lose PASM or trigger warning lights?
No. The TL-HAS retains your factory dampers, so PASM electronic damping and the driver aids that rely on it stay active. You are changing the springs and ride height, not removing the adaptive dampers.
How much can I lower the car?
Front lowering is 15–35mm and rear is 20–40mm, adjusted independently so you can set both drop and rake to taste.
Does it fit 4WD cars like the Carrera 4?
Yes. The kit fits the 991 and 992 in both 2WD and 4WD, including the Carrera S 2WD. Confirm your exact model when ordering.
Should I get this or full coilovers?
Choose the TL-HAS if you want to lower and corner-balance while keeping PASM and factory ride quality. If you want fully independent damping adjustment for serious track use, full coilover options exist for going further.
