We all know that the Motorcraft sport shock have become an unobtainable commodity. So for my '04 V8 Sport, I started looking into the '00-02 Jaguar S-type shocks for more options. Tops on my list are the Bilstein shocks, which are offered in either the B4 or B6 for the '00-02 Jaguar S-type. From what I have read the B4 for the Jaguar S-type are a mono tube design, which is typically reserved for the B6. The B4 would be basically a replacement unit, while the B6 is a heavy duty or sport unit that would work for coil-over conversion. Bilstein also made the electronically selectable adaptive shocks that came as part of the Sports package.
Not sure about their relative firmness to each other, but I have found that for the '03 and later Jaguar S-type factory shocks (which were also made by Bilstein), the difference between the factory stock and Sport shock are about 10% firmer in rebound and about 17% firmer in compression. Not sure if this has any impact what so ever on the Bilstein replacement shocks for the '00-02 models. Not 100% sure which one I will select, but I am leaning toward the B4 shocks - mostly because I don't want the ride to get too firm with our wonderful roads around here.
With any '00-02 Jaguar S-type front shock, the lower spring perch has a smaller diameter than the one on the shocks used on the Lincoln LS. That means you have to use a front spring for the Jaguar S-type as well. Now I do not want to use a set of lowering spring, like those from H&R, as I am not looking to lower the ride height. So I started looking into the factory Jaguar S-type springs. They list two springs for the '00-02 Jaguar 4.0L V8 applications; #XR811166 with the adaptive suspension and #XR811172 (which may have been superseded to #XR835298) for use with the base suspension. As a point of reference, there are also two different and unique springs listed for the V6 models with the same distinction. I can not find any data on the differences with these two V8 front springs - mainly their spring rates. I can only presume that the springs for the adaptive suspension (again which is part of the Sport package) are somewhat firmer because the adaptive suspension had a firmer/sport setting on the shocks.
I know I am out on uncharted waters here, but I have a couple questions;
- For the brave few who went with the '00-02 Jaguar S-type Bilstein shock, did you choose the B4 or the B6?
I can't see the the photos anymore to know if edrurdoe used B4 or B6 shock

Based on the photos it looks like LS_Monk used B4

- Has anyone tried the factory Jaguar springs with any '00-02 Jaguar S-type front shocks?
