I am trying to work out what the original suspension would have been on my 73 911S Targa.
The front struts look like they are the original Boge struts. I think the may now have Bilstein inserts and the rear are Bilstein.
Does anyone know what the original set up was ?
Can this be replicated.
I think the ride is just a little hard with the current set up.
Thanks
David
I'm going to guess that Boges were standard on '73 S. I've got Tourist Delivery option lists for both '71 and '72. In '71 Konis appeared to be standard on S, the option list notes the Koni shock upgrade (M402) was available on T & E only. For '72, while prices were different, M402 (Koni) and M474 (Bilstein) was available on all 3 models, T, E & S. So maybe the same was true for '73.
As per price list in 73 Konis were available as an option of T,E and S. No mention of Bilstein.

Boges were the only shock factory fitted on Targas from the factory.
Before you do anything...how old are your tires and what is your ride height.
Front Tbar 18.8 rear 23.
What Bilsteins are fitted? Green HDs or yellow Sport?
My 73 S Coupe has green Bilsteins (Bottom roll pin) but then it is a sportomatic with factory A/C, so maybe that makes a difference.

The rears are green with the code F4-B46-0169- H0. The front are yellow but have a code written on them 1600P36 0112HO.
Intersted to know what this tells us.
My tyres were newly fitted during my ownership.

As was said in post #4, green are H.D. Bilstein, yellow are sport Bilstein.
Gled49 and RSTarga agree that Boge would have been fitted.
What is the nearest I can get to the original suspension.
Bilstein offer a number of options that mention Boge but I'm struggling to work out which if any are suitable.
Any help gratefully accepted.

Most similar to the original Boge shocks and inserts available today are Sachs brand. Boge was the shock division of Sachs (or maybe the parent company of both Boge and Sachs). They have phased out the Boge name now and market them as Sachs.
Came across this thread...I am restoring an early 1973S Targa with low miles that was parked in 1983. It has Bilsteins all around, and while its possible they aren't original, they certainly look original when looking at the bolts and markings etc.

My 73S targa came factory with boge struts but the inserts must have been exchanged when near new for bilstein. The rears green shocks had early 73’ date codes .
My 73’E targa came factory with Koni so don’t understand the claim that targas were only supplied with Boges.
Original rear bilstein Had blue tape wrapped around the bottom tube and not that modern printing . They would be date coded as were early bilstein front struts .Quote:

I have no way of knowing for sure but pretty sure it was there from day 1.

The bilstein rears were marked with 8mm cloth tape as were the boges, sometimes in blue or yellow cloth tape, front and rear. The bilsteins front struts did not have the tape marker.
What’s your bilstein code?

Car long gone Robert so can't confirm
I’ve owned two targas that were factory fitted with Koni .Quote:

Here is a picture of my front shocks - sorry its not full - but you can see the Green top and the bottom is black. I am ordering some new inserts, but this post and this picture have made me reconsider if I am correct ordering the "Bilstein inserts for Bilstein shocks" vs the "Bilstein insert for Boge shocks"?

OK, so I answered my own question. Mine were switched out from Boge to Bilstein. 911-341-079-00
