Bilstein Shock Absorbers Parameters?


APka

Recommended Posts

Hello everyone ! 

 

So after having read through a great many pages of the stance thread, I have decided to lower my car, by getting shock absorbers and springs.. From what I can tell most people use Bilstein B6, so i'm guessing that's one of the better ones to get? 

My problem, is that when searching to purchase them, I am confronted with 2 different models. The first being the 34-000236, and the second being the 34-000250... The difference? None, except for the "parameters". Let me explain

 

The 34-000236 has 160/75

The 34-000250 has 200/85

 

What are these different mesures exactly? 

 

Please ask me for more info as I most likely left important things out,

 

(Also, if you don't think these are the best choice for shock absorbers, let me know which ones are better!)

 

Thanks in advance,

spent like 7 mins searching this as I never recall the p/n's, and I wanted to offer correct info...........you  couldve searched as well 

 

your numbers appear to b sports vs HD models. The parameters as u call them seem to just be the rates....rebound and compression

 

depending on how low u go on the drop/springs  u will need sports to prevent bottoming out of shocks............if u dont go more than 1.5 " or so HD will be good.....it just depends on what u r doing w/ the car and how it will b used.

 

Billies are well liked, so are Koni shocks

I appreciate your time, 

 

I did actually find out that the difference was indeed sport vs comfort, several minutes after posting, but I left the post to get an explanation regarding the parameters...

 

So the 160 = the height of max rebound..?

And the 75 = the stiffness ?

Not sure what the units are but consider them against each other. The piston in the shock has two, one-way valves. The hole in the rebound direction is 160 (mm? Yards? Furlongs? Microns?) and compression is 75.  So it is a bit less than half the stiffness in one direction to the other.

160 kg at 1m/sec (or some other metric unit of force to cause movement of some distance in one unit of time) in compression,

75 kg at 1m/sec for rebound.

 

The numbers, as my pompous high school physics 'profess-er' used to say, don't mean anything without units.

 

But it's compression and rebound rates-  you'll need to get the units from Bilschtein.

Subjectively, you can say that the second shock you posted is a bit stiffer than the first.

Thank you very much for that explanation ! 

 

I may end up chosing the "sport" / stiffer option, seeing as people say that they fit better with non OEM springs, and the comfort ones are better with OEM springs... Seeing as I want to lower a bit... 

 

Anywyay thanks everyone for the information !

At least in the US of A, the HD Bilsteins seem to be bought more by folks who want improved handling but not a really harsh ride (roads in parts of the US aren't the smoothest!).  Those how favor all-out performance or are going to track their cars prefer the sports, which are considerably harsher--at least on a 2002--than the HDs.  HDs work fine with lowering springs.  My '73 is set up with HR lowering springs and Bilstein HDs and it's great for the street, twisty back roads and periodic autocrossing.  All my suspension bushings are OEM rubber except for the sway bars.  AFAIK Bilstein doesn't make "Comfort" shocks for 2002s, just the HD and Sports.

 

Interestingly my E30 has Bilstein sports and lowering springs, and the ride is no harsher than the HDs on my 2002.

There's a difference between models in the Bils type designations- the E30 'sport' is a shorter shock, whereas the 2002 sport is a stiffer shock

that's the same length as the HD.  I do not know the damping rates of the E30.  This has been a confusing point since before my time...

 

I retract the kilograms- it'd be Newtons, since it's force, not weight.

 

I'm surprised the HD and Sport numbers are as similar as they are- the Sport 2002 shock is quite 'stiff', as in highly damped.  I have HDs, kicking around, I've

just never tried them...  I should, I guess, huh?

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
