Bilstein B12 kit question

[Will.I.Dub 11]

Hi guys, just got a B12 kit for my VR with plus suspension, fitting instructions say I do away with the VR springplate 357 412 341 A and use 1 H0 412 341 A. From what I can see that is the older type spring plate and presumably I need the corresponding older type top mount. Any help greatly appreciated!

Hi Will, I had this issue not too long ago.

you just need the plate and not the mount. This is only to accommodate the larger diameter springs.

VW heritage list them, but i got mine from TPS, little more expensive but quicker turn around.

Thanks Alex, so would that be the combination pictured below? They don't seem to sit particularly well together. I'll give it a go!

So here's how it sits on the B12s

 

 

 

Three finger gap at the front, two at the back, I will let it settle for a couple of hundred miles and see if the front comes down a little.

So as grrrallye correctly says the early VR top spring plate is required. Pics for reference

 

 

 

On left is '90 valver, center early VR and right late VR

Despite the offset difference of the flat face the early and late VR plates don't look too different. What is the effect of using the late VR plate?

The diameter of the top of the spring is smaller in the later version, the B12 kit has a larger diameter spring despite being 'plus axle' specific

I'm getting mine delivered today, so front is the early mount e.g. http://etka.cc/vw/part_single/catalog/vw/markt/RDW/modell/COR/year/1991/drive_standart/76/hg_ug/411/subcategory/102005/part_id/3705862/lang/e#sec_8

 

What about the rears? Did you need early rear spring discs too? (http://etka.cc/vw/part_single/catalog/vw/markt/RDW/modell/COR/year/1991/drive_standart/76/hg_ug/511/subcategory/106010/part_id/3705862/lang/e#sec_5)

This explains a lot to me, i thought there was only two, the left and right one. When i tried fitted early style suspension spring i ended up with the left plate and thought it didn't work too well, so bought different suspension :lol:

The rears just slot in using all the original hardware

[Will.I.Dub 11]

Little update, about 500 miles after fitting the B12s the front had a 3 finger gap and the rear settled to barely two. It felt horrible on the rear, almost sitting on the bump stops all the time and a bit nose up. Weight distribution obviously felt all wrong. After a bit of research here and talking to my supplier and filling out ride height info forms for Bilstein they supplied me with a pair of replacement rear springs.

 

From L - R first supplied spring, replacement in centre and stock on right

 

 

How it sits now on 16s

 

 

Great setup on the road, not at all crashy but nicely firm and planted

Looks good. I bought a set of these and fear I will have to get replacement springs too when the time comes to fit them.

Me too, although the ones I have fitted are the ones you had as replacements. I used SeanJaymos thread as a reference, and I've just provided part numbers and measurements to Bilstein via Demon Tweeks. Will see how it pans out.......

[Will.I.Dub 11]

Sean are you saying your longer spring 8502002HA has settled and the car is now lower at the rear?

[edd 0]

Bit of a hot topic for a few of us at the moment that bought this kit a while ago but are only just getting round to fitting. Has anyone got the measurements of the length of the faulty Spring against the length of the new spring (would the length of the faulty Spring have reduced in use, does it need to be taken before put on)

This is the rear Spring in the kit sat in my garage!? Is this the same part number as your faulty one?

Would be useful to know, what are the Part Nr's of the incorrect spring and it's correct replacement?

 

Ian.

[Will.I.Dub 11]

The part number is the same but the markings are different and they're marked Eibach B/Y where yours are Eibach A/N.

 

The numbers are incorrect spring: Eibach B/Y EW 85 13 002 HA

 

Replacement spring they sent: Eibach KRA 90501, 85 02 002 HA, C/Q 8530

 

To my mind it makes a bit of a myth out of the 'matched spring & damper for your specific car' sales line.

Early and late VRs had different spring lengths, even though they were both "PLUS" 5-stud wide-track suspension set-ups. Mine is a 93, and was noticeably lower than any later 94 or 95 cars I've seen, and that was on stock suspension with 35K miles on it when I bought it. If you check the parts list, you'll see that the shocks are more less the same but the springs differ in length, and the part numbers are different based on chassis number.

 

The spring plates were then also changed - that's your mystery there - after-market suspension suppliers don't cater to this difference and only offer 4-stud or 5-stud set-ups (normal or Plus Achsel) for Corrados and Mk2/3 Golfs because it doesn't make sense for them to manufacture parts for all the variations.

 

This is why the front spoiler also changed in height from 90 to 50 mm on later cars - customers felt the car sat too low and the spoiler was rubbing on the ground.

 

That's my two cents input into this particular classic VW mystery anyway.

This is the post I used as reference, and linked it into an email as further evidence for Eibach.

I have the 3002 set fitted, but believe it should be the other spring set sent out in this link (2002). As you can see, its clearly longer.

On the left is the original that was sent out and settled way too low, number Ew 8513002, the replacement is 8502002

Sorry for the confusion, I got the numbers mixed up. I have 3002 fitted but need 2002.

Glad i went with HR springs :lol:
