Spring rate for rear coilovers

[owdlvr]

It still wonders me how a 944 with the engine in the front runs the 23,5mm stock in the rear and how that can be an acceptable upgrade for a sporty beetle with the rear engine?

A 944 weighs in at around 2700-2900lbs, with nearly 50/50 weight distribution.
A 1303 weighs in at about 1950lbs, with about 40/60 weight distribution.

So, roughly 1400lbs static weight on the 944 rear vs. 1140lbs static weight on the Beetle rear.
