I assume these are for standard shocks.

Inverted shocks have the bump stop inside.
From my experiences over the last few day's I wouldn't advise cracking open the STi shocks to replace the bumpstops, as either the nut is siezed or the inner locating lug rounds off.
Not a job for the average Jo......because you then need to grind the nut off and investigate welding the damper back into the base of the shock housing when you re-assemble.

Bilsteins are easier to crack open as they use an Allen Key similar to the top of the struts. Although I still wouldn't be too keen to crack my Billies open.

Correct.

I think Bilsteins may be reverse thread

Coming together nicely, and what that shows is that the range of Prodrive WR springs (Blues & Grey's) have always sat a touch lower then the P1 springs.
Which is what was often thought/rumoured and is now proven.

I wonder why the very last run of Prodrive Bilsteins were shipped with Red P1 spring's instead of the Grey's.

890 WR springs fitted, showing a pretty linear formation compared to some of the others.
These are the correct spring for the damper of this era, and ride pretty well.
Also added to Post 69 to include with other spring images.

Hello,

have found this nice thread.
I´m also going with the bilsteins on my V4 STI RA.
I´ve got this springs:
Front: Part Num: ST2040055000 (Front, K39) K=39N/mm (4.0Kgf/mm) 224lb/inch
Dots Color: white over red
Rear: Part Num: ST2230055010 (Rear, K32) K=32N/mm (3.3Kgf/mm) 185lb/inch
Dots Color: red over blue
Here are some pictures:




I will post more pictures.
But before I want to tell you my problem and I hope you can help me.
I put the new bilsteins with new springs in my car and there are always clunking noises if I run fast over small short bumps.
So my concrete question is: What have you done with the original washers (they came like you can see it on the picture with a binder fixed at the damper) in second picture which I have painted with an orange circle??
I really don´t know where I have to mount this washer! It doesn´t fit right in any place I tried to put them at the damper. So if you have any idea/expirience with this washers tell me please.
THANK YOU

Sorry for my bad English, I´m from Germany
kind regards
robert

schrobatt

sorry for bad pictures.However you can see a big difference.
please look.

before:
with original dampers and springs


after:
new bilsteins and new sti ra springs



ride height is much more with new dampers as you can see, especially in the front!

Old vs new spring:

2pot

iTrader: (3)

That front spring is:
ST2040055050 5.1kgf/mm 284lb/in
It is the correct front height.

The matching rear is:
ST2230055090 4.9kgf/mm 276lb/in

The noise you can hear is the lower coils banging together. It's how they work. You could put sleeving on the second and third coils. For the front, starting on the coil above the end of the spring, 1.3 rotations of sleeve/protection/isolator/tube. For the rear, 2.25 rotations.

They're great springs; on a tarmac rally stage or autocross.

Can be used on the road, they just look a bit odd.

I've used them with koni's

The big washer fits on top of the damper under the gaiter and I believe its only purpose is to prevent the gaiter sliding down the damper and allows the gaiter to be clamped between the damper and top mount.

The big washer can be used for new age cars and fits between the top mount, but need not be used, even in the new age scenario, so ignore it

@ Schrobatt - something to remember is the front fender gap is bigger than the rear so an equal looking gap front & rear means the rear is lower and therefore the car has quite a negative rake

@2pot:
first time I mount the dampers without a sleeving. After first drive and clunking noises I put over all 4 springs a sleeving.
Unfortunately it doesn´t help much! I know that´s how they work but not with such strange noises. It takes too much confidence while fast driving to me because there are doubts that all works 100% right. The ohter think is, that the bilsteins+springs are not really cheap...for this price they should be quiet!

Thank you all for infos relating to the big washer!
Now I know it´s not the problem of my clunking issue!

I have an other guess why they make so strange noises. If you have dampers without springs in hand and pull piston rod fast to endstop (at the top) you can also hear a "clunk". I think it´s normal but if the motion of the piston rod is faster and spring rate is higher....hm maybe it could be the reason...I don´t know.


"@ Schrobatt - something to remember is the front fender gap is bigger than the rear so an equal looking gap front & rear means the rear is lower and therefore the car has quite a negative rake"

@bonesetter: Sorry, I don´t understand what you mean..my car has now a negative rake because front gap is bigger?

Creepy

A few years ago I was lucky to find a new set of bilstein WR shocks on the bay.
They were literally brand new, in the original packing.

I ordered also a set of red Eibachs from Roger Clarck I think.

My classic performs very ell, no strange noises and perfect handling for mu taste.

The rear roll bar came up in conversation with the original designer.
As the rear spring rates were increased to 224lb/in, on the wr99 suspension kit (page 12 in the link) the rear bar was reduced to 18mm.

Dear All,

It's a very intersting post... Anyway, I have a set of Bilstein Prodrive dampers and blue springs on my GT. I bought begining of june a set of Bilstein Prodrive dampers with grey springs. Please find bellow some pictures of the set just after sanding.




I know that on the 'Performance' kit the springs are blue and on the 'Professional' kit the springs are grey and slightly harder ride. Could you please tell me what is the difference between the grey and the blue springs?

Thank to France

There were at least 3 sets of blue springs and at least 2 sets of grey springs.
And at least 3 sets of Bilstein dampers.

What numbers, if any, are on your springs and dampers?

If you've got the wr99 grey springs and dampers, they have the same spring rate front and rear. You must use an 18mm rear roll bar, that came with the wr99 suspension package.

Ride quality is more to do with the damper, rather than the spring rate.

GT38

3 sets of blue springs and 3 sts of Bilstein dampers!!! Incredible...

Actually, on my car, I have a set of Bilstein Dampers with blue springs. The parts number of the springs are 2230055060 and 2040055040.

In the aim to change the set of dampers and spring which is actually on my car, I bought a set of bilstein dampers with grey spring. Please find below the part number of the set:

Right rear: RH2220055120 (SN : 3300VE34628M0)
Left rear: LH2220055130 (SN : 4300VE34627M0)
Right front: RH2030055120 (SN : 3300VE34626M0)
Left front: LH2030055130 (SN : 4300VE34625M0)

Grey springs: Eibah 96/00

According to your previous thred, could you please tell me how I can find the difference between the 3 sets of Bilstein dampers? Do you think that there is a difference between the set of dampers fitted on my car and set that I bought with the parts number behind?

Thank in advance...

2230055060 and 2040055040 are normally found on Bilstein RH2220055120 LH2220055130 RH2030055120 LH2030055130

WR99 springs are normally found on Bilstein F4VE34625M0 F4VE34626M0 F4VE34627M0 F4VE34628M0

P1 springs were sold off with Bilstein F4VE34625M0 F4VE34626M0 F4VE34627M0 F4VE34628M0
I'm not sure what the match was like, as while the front springs are similar, 1 N/mm softer, the p1 rear are 7.5 N/mm (43 lb/in) softer.

Please post a better picture of your grey rear spring - it looks like a wr99 rear.

GT38

First, please find below picture of rear Eibach spring actually on my car. As you can see, the part number is 2230055060.



Then, please find below picture of grey Eibach 96/00 before sanding.


The height of the front spring is 22cm and 25.5cm for the rear spring. Do you think that it's 22B springs (picture in page 3 of the thread).

This is a great resource, here's a contribution.
A few weeks ago I fitted Prodrive Bilsteins with the blue springs to my uk '99 wagon ppp, with OEM 16" wheels, 205/50 16 Nokian Zlines.
Part numbers:
Front springs 2040055040 (48 96)
Rear springs 2230055070 (49 98)
Front strut 20 300 55 130 (4698ve34261mo)
Rear strut 22 200 55 120
Ride height front: ground to arch 635mm
wheel centre to arch 348mm
Ride height rear: ground to arch 612mm
wheel centre to arch 325mm

Alignment (my choice, I'll see how it goes...)
Front: caster 3.9 degrees (alk fitted)
camber -0.7 degrees
toe 0.3mm
Rear: camber -1.3 degrees
toe 0.3mm

This is lower than I would like for rough road ground clearance reasons, especially at the rear, and also I'm not too keen on the saggy butt look. However, it drives brilliantly, far more controlled than the standard setup over the sometimes bizarre combinations of surfaces on the back roads. I'm keeping the 16" wheels for now, as I don't feel there's anything I need to improve on at the moment, although of course this may change....I may get some saggy butt spacers though.
Here's how it looks

Thanks for posting that info; very useful
Wagon-wise, you've, perhaps, an extra 35kgs shared across the two rear springs.
Should the P11-6 springs get made - 640mmish/640mmish on a wagon, with half a tank of fuel.

GT38

Very interesting... Actually fitted on my car, I have 2230055040 spings set up for the front and 2230055060 springs for the rear. Using 17" wheels, 215/45/17 Bidgestone RE002, ride height front or rear is 635mm (ground to arch).

Anyway, please find below picture which we can see differences between the Grey spring and the Blues... For information, Grey springs became blue after sanding and painting





As you can see, the Grey sping (Professional kit) is little shorter than the WR kit

And finally, please find below a picture of strut after sanding and painting! It look very nice

I've got some 3/8" spacers on the way from Paranoid to sort out the rear ride height, and as I say, the blue springs match the early Bilsteins perfectly, but I'm aware that if I was to break a spring, it would be hard to find a replacement, so I'll put my name down on the other thread for a set of P11-6.

Your ride height sounds about right for WR Blues/Grey's.
The Lowered STi Pinks, which are the closest currently available spring to the WR Blue measure around 630-635mm depending on fuel load and ambient temperature.

Although the Grey (which you have painted Blue) is shorter then the original Blue, the Grey is a higher rate and hence when fitted will give similar ride height despite being shorter.

GT38

Thank for the feedback. However, I have one request concerning the big washer. I don't remember where this washer was fitted into the damper.

Is it according to the following picture?

no, spring seat then washer and then strut top with bearing.
