Just installed 12mm H&R wheels spacers, on all 4 corners, on my ZTK package G42.

Part number B55664-12.

The rear is damn near flush now. Install went very smooth. Chose them for their TUV certification.

This is interesting (and I may have observed this before).
Currently have 12mm spacers all round and I have the ZKT pack.

However, I feel my rear wheels poke too much so I’m going to change to 10mm on the rear. The poke obviously varies slightly depending on how aligned to the car you are, but unless you are absolutely square to the vehicle (right photo) I feel, it always looks like the tyres protrude too much.

I can only assume it’s down to the tyres. I have Michelin P4S and I don’t think the car above has.

Very fair… it probably could be 10mm on the rear. I actually had an opposite reaction! I felt the front needed 2 more mm of poke lol. 😆

Either way I’m not sure the look is even front and back with even size spacers.

Some photos from today now with my summer tires on. Both sets of photos are Michelin rubbers with the original post being Alpin 2’s and these with the PS4’s.

Yeah. I think you are right, the fronts need a bit more and the rears a bit less.

It just goes against normal perception that spacers are either even all round or larger on the back.

Maybe the magic is

11mm rear
13mm front 🤪

Might have something to do with the staggered ZTK setup?

I’ve had other BMWs with a staggered set up before.
I think it’s just a corner case with the offset and tyre size (or outer shape)

TBH, I might have gone with 8 or even 5mm on the rear if those spacer sizes were available.
I’ll post a photo with 10mm when I get them on.
