Camber is stock for front and rear. (Sent you my measurments in PM). And no spacers. I just installed the springs and had it aligned and that was it!

I didn’t answer all of your questions.

I thought the B8 has a shorter strut body measured from the spring seat to the top of the steering knuckle? The B8, and Evolve/Bilstein B6, has this shorter strut body length (the first time rear shock length is also shorter) on the B6 and The difference in lengths between the B6 and B8 is ~0.3”. The shorter spring seat (and the location of the bolt centerline on the anti-sway bar mount) length to the top of the knuckle to account for the internal gas pressure acting on the piston valve stack which raises the piston valve stack/piston (pressure x area = lifting force on the valve stack/piston) and, therefore, reduces the spring height. So did Bilstein reduce the length of the B8 piston rod or shorten the length of the B8 strut body or possibly both? The shorter damper body with gas pressure applied to the piston rod would also result in what appears to be a shorter piston rod length.

Yes exactly, the strut body has to be different to account for the ride height difference between the B8 and B6, if like you said ride height is determined solely by the spring and not the damper. In my communication with Bilstein they said only the shaft length was shortened on the B8, nothing else, hence why I was confused and asked the question. But you know how the reps are, some aren't actually experts and are just reading info off the screen...

I agree. Customer service reps are reading directly from canned responses to questions. You’d have to request to speak directly with an engineer or a technical rep.

I’m certain the B8 damper body is shortened because I doubt they would’ve spent the cost of R&D to satisfy Bilstein design requirements and qualification testing to only shorten the damper body on the Evolve/Bilstein B6 Damptronic damper. Also, Evolve has stated their version of the B6 Damptronic has been shortened to match the shorter B8 damper body.

I thought you had purchased the custom version of the MCS 1WNR?

I assume the shop reused the oe spring pads in the rear as they should’ve. If they are missing that would make the rear lower. Also the Dinan camber plates actually add about 5mm to the ride height as they go on top of the stock strut mount. This is part of the reason you’re front is so high.

I did I had looked so much into the Bilstein offerings that I thought I'd chime in.

As for accounting for the B6, I went with Dinan springs initially, which supposedly lower 12.5mm/12.5mm (F/R). Those spring performed great from ride and handling, but the front looked still a tad high.

So ended up doing the Eibach Pro Kits, which supposedly are 20mm/15mm (F/R) lowering. I think wheel spacers can have an effect as well, and to be honest, it's a pain when the car is not that lowered. So I've been playing with multiple sets......started with:

12/12 mm spacers F/R
then moved to 18 mm/12mm F/R (which is what you see in the pics)
I then changed to 15 mm/12 mm F/R to reduce the front poke a bit
And now on 15 mm/10 mm F/R
And am thinking of doing 18 mm / 10mm F/R as the final option, which I think will be the best of both worlds. Let's see. hehe
Here's the car now, with 18 mm/10 mm Front/Rear spacers.
- Tires are Michelin PS4 Sports, 245/35/R19 (BMW Star) and rears are 265/35/R19 (USA ver.).
- Eibach springs & Bilstein B6 EDC shocks

I think I'm happy with this spacer combo.

That looks great! Very OE+. The 12mm in the rear before looked a bit too close for comfort.

How are you liking the B6/Eibach combo? Been thinking about going this route for a comfy daily setup.

Yes, scary to say, but 2mm does make a difference and it's really dependent on the specific specs of the tire, which is why sometimes people say 15/12 is the way to go, but others will find differences.

Even on the Michelin PS4 Sports, there are differences between the 2 versions of 265/35/R19. The one made in the US (the one on my car) looks have a wider section width & tread width vs. the Italy version (M01 Merc spec).
- USA ver: 10.7in section width, 9.6" tread width
- Italy ver: 10.6 in section width, 9.3" tread width

Which is why the rears are more squared off. I think with the Italy spec version, I think the 12 mm would work better from an aesthetic perspective, slightly wider track and the tire itself is less squared off and more similar to the front.

Anyways, minor differences that most people wouldn't notice or care, but fyi for those who like to play around.

As for the B6 with Eibach, it's a good combination and I've run multiple Bilsteins on my past BMWs and they are solid and don't fade vs. OEM shocks. Also, having run the Dinan springs as well in the past with the Eibach, I would have to give a slight edge to the Dinan on ride comfort, but at the same time they were slower response on rebound feel vs. Eibachs, so some pros/cons there.

But either way, you can't go wrong and definitely a solid yet comfortable ride with either combo.

P.S. I have my 15mm FC spacers for sale if you want. I'll probably keep the extra 12mm spacer for future use, depending on the rear tire combo I go with.

I thought to ask because I figured there was more to the tires but wow, I had no idea about all that! Those are striking differences. Don't plan on running 19s but that's really good info to know (for those who care, like me ).

Appreciate it! I'm personally not a fan of spacers though, and even then I'm currently on my winter setup so wouldn't have a use for them. I'll be swapping to aftermarket wheels with the proper offsets in the spring.

Good to know on the Billy's. I think Dinan runs softer rates then, or it could be that and that they lower the least of all lowering springs. I'm currently on Eibachs which are pretty nice and comfy.
