Neuspeed Sofsport/Softsport for MkIV
- Front: 200 lbs/inch, linear
- Rear: 160 lbs/inch, linear
Jetta and 2.0L are probably the same rates, but this is unconfirmed.
According to Neuspeed, the front springs are longer on the VR6 to account for the extra engine weight, but the spring rates are the same.
These springs appear to be "progressive" in the box, but when installed, the "progressive" coils bind up to a solid block under the weight of the car. They are there to prevent the spring from falling out of the perch at full suspension droop.
