Bilstein shock sidentification Options

[Montreal914]

Trying to identify what Bilstein shock I have and information is not clear... (IMG:style_emoticons/default/wacko.gif)

Lets start with the back ones as I think this will be easier (maybe). These are yellow and have the 5-6 grooves with the ring allowing to ajust the ride height. P/N is 720 0179 H003. Are these the Heavy Duty, the Sport, or something else? (IMG:style_emoticons/default/confused24.gif) Looks like there is only one option for the rears in yellow with the grooves but they have a different number. Did Bilstein change their numbering scheme?


For the front, I am using 911 3" wedge bolt Boge struts. For this I actually have a selection of 2 sets of Bilstein yellow inserts with part numbers:

F4-P36-0113-H003
052 112 H001 EDIT for typo: 050 112 H001

What to read for both of these two front ones, Regular, Heavy Duty, Sport, other? (IMG:style_emoticons/default/confused24.gif)

Help appreciated. (IMG:style_emoticons/default/smile.gif)

i googled F4-P36-0223-H003 and i am getting a hit on a pelican forum.
seems to say its an old parts number.
accords with B8 performance.
so i would say that is a super stiff shock.
maybe almost a track shock.
i haven't gone into the website just looking at google summary on search page.
i'd have to look further googling.
not getting a match on the other part number you list for front.

can't seem to get anything on the rear part number yet.
must be old part numbers maybe - or more obscure.
