Alpina Front Springs - B12s Ordered

I've got the info on the correct kit from Bilstein,
Unfortunately 2-3 week delivery as Springs need to come from Germany and get fitted to the kit.
Checked with another couple of sellers that said the same.

They also offer 6 months interest free credit which might be useful!

Just get them ordered,you know it makes sense Richie. :poke: :rofl:

Looking at anyone who has them fitted to their Alpinas, nobody has a bad word to say about them....also future peace of mind about an existing shock or 2 leaking,meaning more outlay.
At least with the b12 Blstein/EIbachs kit you are saving yourself more potential outlay in the (probably not too distant) future,given the cars probably still on 13year old shocks.

Thinking of doing my shocks and springs In the next year or 2,all round,given its now 10 years old,and nothing like a new set of springs/shocks to refresh the cars driving and handling enjoyment/ability :D
 
BMW know how to charge,given its over £300 for a pair of front Springs for these,and around £400 for a pair of Shocks!!
Plus fitting of course.

Given you can buy the full b12 kit from as little as £738 delivered,wth 4 shocks and springs,it is shocking,lol :rofl:
 
In Germany we get no MOT (TÜV) with B12 set.
For a normal Z4 you can use this set, but the Roadster S has higher axle load (because of the heavy E36 M3 engine) - and this axle load is not covered by the papers - delivered with the B12 set.

In UK ist seems to be not a problem - good for you.

To get MOT for my UK Roadster S #203 I had to buy 4 new springs and 4 new shock absorbers, had to change the brake (front original Alpina - back is M3). I also had to redo the entire exhaust system to get german MOT.
:cry:

Alpina lable with axle load data in the engine bay - this one is from my # 280:

I was looking at those loadings but having phoned Bilstein they said set 46-181237 is correct for the car!

Here a link to germany ebay with this set # 46-181237.

https://www.ebay.de/itm/Bilstein-B12-Pro-Kit-Fahrwerk-fur-BMW-Z4-E85/302116807166

Max load front (VA) = 790
And YES, on phone they say this, but not in writing - so we (germans) get not MOT, because in writing it's only 790.

No,so annoying.....you would think somewhere in the UK would have springs or the b12 kit in-stock for the 3.0/Alpina zeds :headbang:

I thought M parts were a pita when it's up to 2 weeks for some things.

The shocks and springs on the Alpina roadster were, "Sachs" That was confirmed to me by an old Alpina owner named Ade. :thumbsup:

Don't suppose you have the Sachs part number Brian?

Sorry Perry I don't anymore I had a clear out of the garage just a month back and only then threw out the ones I removed. I know, bit of usless info really without the part number :!: :roll:
 
Sorry, bit late to the conversation - Rich, you have a pm.

I did have a spare set of Alpina OEM springs, but they went with the car when it was sold - marcusG on here is the new owner.

B12 is a good bit of kit, but as manfred points out, they are for a lower axle rating than the Alpina's front lump. The indy I used (who raced BMWs) stated that unless I was driving at the limit, there wouldn't be any issues with the slightly lower axle rating.

As Alan mentions, they are a good alternative - tbh I found that on decent roads they are better than stock, but the slightly lower stance (whilst helping the handling etc) can make the ride a little crashy on the crappy local roads here.
 
Not sure if it helps but if you go to the following thread https://z4-forum.com/forum/viewtopic.php?f=7&t=29715 there are some pictures of the springs that I took off my Alpina a few years back.
 
Eventually ordered the B12s - £720 delivered
Couldn't find anywhere that had them in stock but they should arrive start of next week! :D
Should I be changing anything else at the same time??
 
I changed the topmounts at the same time - rogue engineering in the rear will help if you ever need to change them again!
