I guess this is a good reason not to go on a diet.

There are also Adjustable Ride Height coil over kits that you can add to your car to give you M030 type of ride height adjustment.
1) Do S2s with M474 equipment have the same ride height as S2s with standard suspension ?
On S2s, M474 equipment features springs that are 11 mm shorter than springs of the standard suspension set up although they have the same stiffness. WM do not specify much about front ride height on S2s, either with or without M474 ...
In my experience, fitting M474 Koni shocks with base suspension springs results to increasing front ride height.
2) Does that mean lower spring perches are actually positoned "higher" on M474 Koni struts than on base suspension Sachs struts ?
I should have measured when I replaced the shocks ...
Many thanks in advance.
(PS : base suspension springs on my S2 were replaced with 968 CS springs since, but that has no influence on my two questions above)

Ride height is important for ground clearance, suspension geometry, suspension travel, ball joint movement limitations (which is what causes catastrophic failures), lower center of gravity, aerodynamics, ect, ect, and I guess looks. That is if anyone can see with their eyes a 1/4" difference. As long as you are not lower than the limits Porsche recomends for the stock suspension, what is more important than making all corner measurements "equal" is corner balance.
Corner balancing is the method used to get each wheel supporting as close to the same amount of weight on each tire. This is done by raising or lowering each corner. A properly corner balanced car will handle better, but will not necessarily have "equal" height measurements.
Chassis can flex, body panels can move, suspensions can droop, tires wear uneven, all can influence a measurement. The most accurate method is to put each tire on a scale, and corner balance.
