Spring Rate Data

[blkaplan]

After reading this thread many times over, I calculated and had custom springs made for my 1992 244 sedan. The aim was to achieve both lowering and ride comfort. The cost was about 400 USD for all four springs.

Front 98 lb/in
410 mm free length
165 mm overall Diameter
13 mm wire diameter
4.65 free coils
5.5 entire coils
205 mm installed height sitting

Rear 120 lb/in
300 mm free length
127 mm overall Diameter
11.5mm wire diameter
5.14 free coils
6.64 entire coils
163 mm installed height sitting
71 mm block height.
※Rear springs are used with BNE rear coilover.

As a result, it became a car with an exceptionally comfortable ride. It's ideal as a family car for city driving.

that thing must be smooooth.
