Maybe you can calculate it: FAL raises the car by 30mm......

Do you know if the axle lifts 30 mm, or the nose? Some quick numbers give me 7.2 degrees with a 30mm nose lift, 7.9 degrees with a 30mm axle lift.

As I understand the lift is measured at the axle. The nose measurement would (obviously) depend on bumper, spoiler lip, etc.

Porsche describes it this way:

An optional lift system at the front axle raises the front end by 30 mm. Operable up to a speed of approximately 50 km/h, it minimises the risk of grounding on kerbs, ramps and car park entrances.

I guess it depends on how you interpret "front end".

Yes, this is open for interpretation

Some more details:

"The function module is a compact unit located at the front of the centre tunnel and is approx. 80 cm long. The pneumatic compressor generates pressure of up to 20 bar if required. The pressure reservoir has a fill volume of approx. 1 litre and stores the pressure required for the system to function. The compressed air system is controlled by means of a valve block unit. The system weight of all components of the front axle lift system is approx. 7 kg."

The ramp break over angle is 5.1 degrees versus 10.3 degrees for the 997.2 GT3 RS.

Is this compliant with your favourite coffee shop parking lot?
Can you tell me where you found this information? Trying to find a ramp solution for my trailer. And I assume the approach angle is based on a single plain, not open in the middle? If the middle is open, do you happen to know how much more the angle is?
