allroad owners: Bilstein B12 prokit A4 vs Allroad fitment

[FastFour]

I ordered the B12 prokit part #46-183323 from ECS the other day and they arrived today. They are for an A4 and lower 1.4 inches front and 1.2 inches rear. There is also part number 46-183354 for the A4 Avant and lower the front and rear both 1.2 inches.

My question before I install is should I return the kit I have that is for an A4 and order one for the Avant? Does anyone know the weight difference (load differences) between the Allroad and the A4 Sedan? I'm just worried I may have an uneven ride height and don't want to install these when I should have maybe picked up the Avant specific model. Can any Allroad owners chime in?

[zcspec]

Yes, you should have purchased the kit for the avant. The back end is heavier and requires either taller or firmer springs.. From experience and as an example, I know Solowerks offers coilovers specific for the allroad due to the weight difference in the back. Get the correct ones as it's better to be safe than sorry.

Got you shook? I would call Bilstein and confirm that the avant kit will be ok.

Two things; one, if Eibach makes a spring specifically for avants/all roads they did it for a reason, why spend r&d, manufacturing and inventory if you don't need it. And two ECS has terrible pricing on Bilstein products, even tire rack is cheaper, the best price AZ members have found has been ajusa.com. I would return it.

ECS offers the b12 kit for under $700. Tire rack is over a grand. What are you even talking about?

Take it easy tough guy, I said Bilstein products in general, a set of sport shocks from ecs $721, tire rack, $674. Wow dude.

[FastFour]

Easy ladies....ECS price is 687 and they're in stock. AJUSA's price is better but are back ordered for over a month. Looks like I'll be returning them tomorrow and ordering an Avant kit. I'll still give Bilstein a call just to see what they say.

He must have just been confused. Probably thought this thread was made to ask specifically about the B12 pro kit. But since it's plainly obvious that nobody in this thread was talking about the B12 pro kit specifically then i agree. OP should return his Bilstein products in general to ECS and then repurchase his Bilstein products in general from Tire Rack where they will certainly be much cheaper than what he paid for his Bilstein products in general originally.

I wasn't trying to be a tough guy......... I was merely confused by your statement. Brah. Yes, if you buy just the shocks ECS is pricier. But I was under the impression we were talking about the B12 kit. I didn't mean to ruffle your feathers.

[dawus05]

Have many B8.5 AR owners installed the B12 kit yet? I haven't been able to find a decent review for this on the AR and it's come down to either vogtland coilovers or the B12 kit. OP good luck with the swap, would greatly appreciate some feedback and pictures once it's installed.

[FastFour]

So after a bit of research today this is what I've found. B12 prokit rear spring part number for the sedan is E10-15-011-01-22 with a spring rate of 171#. The Avant spring is E10-15-011-03-22 with a spring rate of 222#. Not as big of a difference as i thought but enough so that I am returning the sedan kit to order the Avant kit. ECS and AJUSA are both out of stock (of course) so I'll have to wait for any real updates. I'll search around more tonight in the hopes of finding it in stock somewhere that doesn't charge exorbitant prices.

Did you end up installing the Avant prokit on your AR? How did it turn out? How is the ride?

[Project Quattro]

I'm not sure if you've already ordered but several people have run the Avant-specific rear springs and had the back of the car ride far too high. Sedan springs fix the issue.

I can confirm this. There's about a 1.25" difference from front to rear. From what I know Bilstein/Eibach did this to account for the extra load in the back. @Phray is one member who swapped in the sedan springs to fix the rake issue. But to give you an idea on an Avant....

I haven't ordered but prefer not to have the rake. So the B12 A4 Sedan Prokit should fit on the Allroad without a problem? I figured if it's ok for the Avant it should fit in an Allroad but just want to confirm. Thanks.

[FastFour]

Wow back from the dead. I went with a set of Vogtland coilovers and couldn't be happier.

After all these years... Has anyone put a B12 kit (or B8 + Eibach springs) on an allroad B8.5?

[Nenuko]

Another one here interested in the B12 review. Anyone with this configuration?

[mattymess]

I'm interested in the B12 setup on an AR as well. I'm debating between the B12 kit or Sachs sport shocks/struts paired with KW HAS springs. At least with the sachs/kw setup, the rake can be solved without having to get a different set of springs.

I've just read so many mixed reviews about coils on ARs...I really don't wanna put in spacers to fix a sagging rear and sacrifice ride quality...I've read about at least one account for pretty much all the sub-2k coilover manufacturers (ST, Vogtland, H&R, Solo) where this has happened

[spin0rz]

That's funny. I bought my eibach pro kit springs off a guy who had ordered the sedan version and they weren't sitting right on his allroad. So he got the avant version.

He paired them with b8 shocks and couldn't be happier with the results. Ride comfort is great and it's sporty and tight without the harshness.

Edit: for those who may not be aware, the shocks in the b12 kit are b8 bilstein shocks. So it's the same combos, bought seperately.

I'm glad this thread got revived. My B-12 kit is being shipped, and its going on a b8.5 allroad. I ended up ordering part # BIL-46-183521. After reading this thread, it looks like I ordered the wrong kit.

I'm a bit confused...The image above is your Allroad using the sedan kit or his Allroad with the avant kit? You heard from him first hand about the ride comfort on the avant springs?

Seriously...There is such so much conflicting information out there on what works for an Allroad...

Looks like you ordered the Sportline kit, which lowers the front 10mm more than the rear. I'm guessing that would produce some rake

Conflicting info. is an understatement....
I got to a point where I just said screw it, and ordered the sedan kit back in February. They finally shipped it to me a few days ago.
I'm going to put it in and see what happens.
Worst case scenario, I have to put Avant springs in.
The sportline kit is 10mm lower in the front, I'm sure it'll be fine. Either way I'll end up letting you all know how it goes, and what the before, and after ride height measurements are.

The picture is off an allroad with avant eibach springs. He had ordered the sedan version and they weren't sitting right. I bought his springs (sedan) he ordered the avant version which sat right.

His opinion is what I stated about the ride quality over stock.

Not sure what was hard to understand.

That's on eibach pro kit avant version (matched with b8 shocks, so identical as b12 kit).

Sportline will be quite low I reckon.

So you may have to watch out for your bumper on slopes, bumps etc.

Anyone? Bueller?

[porwal22]

Installed the B12 Sportline (red springs) kit, along with Hotchkis front & rear swaybars (A4 kit - 22836) on my B8.5 Allroad. I waited a few months to see if the ride height would change, also if it would ride any different. At first it felt like I was riding on the bump stops. It was not the case, I cut mine in half and used epoxy to join the upper and lower halves of the bump stops together. The first week I wanted to rip the suspension out and put it back to stock. I hated it. I was too used to the stock suspension.
Then I got more and more used to the way it handled, especially on the highway. It's by no means a race car, but it does corner so much better than the stock suspension.
As long as you live in a state where the roads aren't like minefields (like the roads here in Rhode Island), the ride quality and improvement in cornering is huge. It does stiffen up the suspension a noticeable amount, and corners are a blast!
I ended up with 25 3/8" FTG in the front, and 25 7/8" in the rear (with factory 18" wheels).
I'm going to switch the springs in a few weeks to the black "pro" setup, as it scrapes the front mudflaps going into driveways, and switch to 19" wheels. we'll see how it goes. I love the Sportline kit, I'm just getting tired of pullling into driveways at 2 mph so I wont destroy the front end...
