Bilstein question-what's the difference?

[rfuerst911sc]

While searching on various sites including this one I see that there is a Sport shock # B46-0169 and a Rally/Sport shock # B46-0975,so what's the difference?I want to put them on my 83SC which is mostly a street driver,it currently has the oem Boges which I'm sure are tired.Thanks in advance.

As Tim said, for more information, contact Bilstein they can provide info like this Which Bill Gregory recieved and shared for 964 shocks:


964 to '90 (Bilstein HD)
...Front 332/104
...Rear 274/122

964 to '94 (Bilstein HD)
...Front 332/104
...Rear 277/124

964 Carrera RS
...Front 259/84
...Rear 415/237

964 Cup
...Front 220/67
...Rear 379/172

964 RSR (3.8L)
...Front 237/96
...Rear 402/216

The values are read as rebound over compression, ie, the first number is the rebound value with the second being the compression value.

The standard values are decanewtons at a piston shaft velocity of .5 meters (500mm) per second. A decanewton equals 10 newtons equals about 2.2 lbs of force. (Reference: an excellent two part article entitled "996 Standard and Sport Suspensions Analyzed" in the April and May Pano's).
