Anyone out there know what porsche uses as oem springs in c2s pasm (non sport) and the comparable H&R equivalent if there is one? I'm considering H&R oe sport springs which lower 0.25 - 0.75" on average per the product info. Not sure if this is equivalent to what already exists on the car.

 

PASM springs are 10 mm lower than stock or ~ 0.4 in
SPASM springs are 20 mm lower than stock or 10 mm lower than PASM
The new GT3 springs are 30 mm lower than stock
