Not sure if anyone can help with this, but were Monroe/Boge dampers off the shelf third party supplier designs adapted to fit the 993, or were they an entirely bespoke design, developed for the 993 in conjunction with Porsche?

As Bilstein HDs were not developed with Porsche for the 993, should I be worried about using them on my 993?

Any Bilstein is an improvement on Monroe or Boge.

The Monroe shocks are specifically for the 993, Boge werent fitted for very long, doubt if you have them on a 96 car

Have already got HDs on my 993 but there is talk from one corner of 911uk that it's better to stick to Monroes as they were designed in conjunction with Porsche. According to one person in particular there are well documented handling problems caused by the fitment of HDs to a 993. I must admit, that despite searching, I haven't found any evidence of these 'well documented' issues.

This sounds like bull to me as I've seen a massive improvement in all aspects of handling since fitting HDs.

Just curious to know if there is any value to the 'sticking with Monroe/Porsche developed dampers is best' argument.....

I bet all the "handling issues" is from shops not being able to do a proper alignment after the HD install.

You would need some seriously bad shock to make a car handle worse then crap blown shocks. I happen to like the stock shocks, they just don't last long!

Porsche or other auto maker designs and work together with technical labs of several companies at model launch.
They guaranty 2 years of preferred supplier for the part developed usually,
IIRC, the initial laboratory who developed the 993 shock absorbers was Boge (ZF and Bosch owned company)
GEA Bischoff was chosen for the emission system (catalytic)
Two years after, Tenneco won the bid and supplied the monroes and the Gillet cats
same product criteria and norms
Bilstein were always on the porsche 993 option catalog, the pss9's option code 000.044.500.02
the HD's I am sure were built with the same product criteria and norms, and maybe exceeds these.
If the person saying the Bilstein were not designed with porsche, then neither the monroes were, nor the gillet cats nor plenty of stuff, brake pads, filters, sensors, PISTONS, spark plugs etc etc
it's all a question of pesos

edited: and forgot to mention that bilstein yellow struts were original mount on the RS. not the HD's nor the pss9's

Im afraid this is the site for info, not 911UK. I dont believe anythig on there unless it is verified on Rennlist. (lets face it the site doesnt even know the models years for most 911's, ie; 911SC in 1977? 964 ended in 1993? 993 started in 1993, 996 started in 1997 and the 997 started in 2004)

I dont think that Bilstein was an option on 993's from Porsche, standard on the RS yes. The 000.044.500.02 kit is for a turbo and Monroe I think, were PPS9 out way back then?

Bilstein are a huge improvement on Monroe or Boge end of

Cristel993

Awesome insight Geolab, thanks loads. Really makes so much sense. If Porsche switched from Boge to Monroe, I doubt they would have put the same amount of R&D funding behind an entire redesign, as with Gillet etc.....

geolab

Yes bilstein was an option, 000.044.500.02 IS bilstein pss9, I take bets

911PERVY

I suggest you look at the parts list for 000.044.500.02 it is not a PSS9 kit

PSS9 have only been on the planet this century

Now how much shall I bet?

geolab

PART NUMBER 993.343.980.01 is a front left bilstein pss9 shock absorber for 993
the kit today costs (installed) 5205 euros before TAX at dealer
I suggest you take a membership

You seem to be moving the goalposts.............

Anyhow, Bilstein PSS9 kits are an aftermarket kit, they were introduced in 2001 ish

The PSS9 is not available from Porsche, it wasnt even a thought back in the mid 1990's so couldnt be specced on a car!

Bilstein shocks are available now and were available back in the 1990's (the part you list isnt adjustable, its a shock absorber, link here;http://cgi.ebay.de/Porsche-993-Feder...-/320596676406

The RS had Bilstein shocks, these can be fitted to a non RS 993, again non adjustable

The kit 000.044.500.02 lists wishbones, sway bars, wheel hubs, carriers and god knows what else, it is also only for a turbo

As for membership....................what did Groucho Marx say?

Zuffenhausen :O)

911 UK is a good source of info it just depends who you ask, some members have a rather excellent imagination unfortunately

You're just fine on those HD's Cristal.

911PERVY

Yes, youre right and Im sorry if my post came over a bit harsh on you guys!

As you can see, there is mis-information on this site too..........

geolab

were can we verify this info?


Wrong, this ad is wrong. Listed is two shocks part numbers
993.343.041.80 and 993.343.042.80 these are the shocks originally on RS

and you forgot to mention the shock absorbers !!!

Now if you say the kit 000.044.500.02 is not PSS9's
well we all know that ROW turbo is euro M030
and the kit 000.044.500.02 proposes 15 mm lowering for the euro M030 turbo
so what are the shocks in the 000.044.500.02 kit?
call your dealer
I called mine
