I am sorry to beat a dead horse with all the discussion of CS vs. CR shocks, but it seems like the
Porsche
catalogs list 2 different part numbers. However, when looking at the
Bilstein
part numbers, same part numbers are listed:
22-147578
front and
22-147585
rear. This would lead me to believe that the shocks are actually the same. Can someone confirm or deny this?
the
Bilstein
part numbers are for B4 OEM spec. I don't think they have base/S/R specific models.
if you're keen to try
Bilstein
go for the B6 (normal height) or B8 spec (lowered) which is sportier (stiffer).
if not go for
Porsche
branded.
In order to ensure good configuration control it is not unusual to assign specific part numbers for specific end items even if the part is the same. i.e. future updates may indeed change the specific part, shock, for the CR relative to the CS. This change may now just be fazed in with time, without having to introduce a new part number.
Sorry I was operating under the assumption that
Porsche
just puts their own part number of
Bilstein shocks
and sells them as their own. Do they make their own shocks or is it another company altogether? I purchased
Cayman R springs
and am trying to find the most cost effective solution. I am open to any brand, but I have not seen anything other than
Bilstein
. What are my shock options ? Would reusing my current 09
Cayman S
shocks be a bad idea? (Shorter life, shocks not matched for spring rates etc)?
I spoke with
Bilstein
customer service. They could not confirm if
Bilstein
is supplies the shocks for
Cayman
. I was told though that the B4 shocks are made to factory specs and I should be ok using B4 shocks (same PN between
Cayman S
and
Cayman
R) on my
Cayman S
with
Cayman
R shocks. Has anyone tried this setup? It seems like most people with the
Cayman R suspension
retrofit (on here) bought the entire setup together shocks and springs. I found new springs for $500 (set) new and B4
Bilsteins
run about $200 each, so ~$1,300 total vs the kits I've seen running ~$2,400. Has anyone tried this setup -
Bilstein B4
and
Cayman R springs
or can comment on it?
Bilstein
B8 sports will work very nicely with
Cayman R springs
. I had that exact setup (except for
Boxster Spyder
springs) on my
987.1
Cayman
. I also installed a
Cayman R rear sway bar
(the front bar is common to both
Cayman S
& R). Get a
Cayman
R wheel alignment, and you'll be good to go!

Croc'ed, curious - did the rear sway bar make a big difference in the overall setup?
Prior to installing the
Cayman
rear bar, I had an adjustable RSS bar. Playing with the settings gave me an appreciation for their handling effects. I preferred a stiffer than stock setting, to dial out some of the inherent "push" or understeer. The
Cayman
R's rear bar is non-adjustable, and stiffer than the S's, so I think it's a no-brainer to add it to your setup. Plus, it's super easy to swap out and relatively inexpensive, so you can always revert to stock if you don't like it. But I suspect you will. [emoji41] Just be advised you'll need to swap out the rubber bushings too, since the bars are different diameters.

sovietmuscle - what did you wind up doing for dampers with R springs?
I have recently purchased an S and the previous owner installed Eibach Pro-Kit springs which are too low in front. I spoke with my local
Porsche
shop and they said since Eibach are designed around factory dampers and the spring rates are similar to R, so I could just swap my front springs with R and it would be a cost effective way. But I have some doubts. Members say factory dampers with stiffer springs make for a bouncier ride.
