Was looking to get the GT a little lower and saw that there are very few spring options for us. I called up H&R and they told me that in Germany(H&R German division) they are using part number 28878-4 for the F34's. This is for the F33. They have not tested them stateside so they could not guarantee fitment.

Not sure if anyone else has heard this or tried these springs. If so I would love to hear your experience.

So I just did a product lookup on H&R Germany and it shows 28832-2 as the springs for any F34 4WD.

Now I'm confused, lol.

Maybe this will help.

ACS sells springs for the F34 xDrive in the U.S.

Seems like the ACS springs for the F30/F31 335i Xdrive (sedan or wagon) are the same part numbers as the F34 328i Xdrive. Would lead me to believe that any F30/F31 N55 Xdrive springs would work with my F34 N20 Xdrive. Most likely because the GVWR of those 2 cars is similar.
