my wheels are OEM but I would like to buy Aftermarket for the summer. I was thinking about doing 25mm since the spacer will have the additional lugnuts embedded in the pacer so that way im not losing threading.

20mm or 25mm (both available as DRA spacers with own threads) is for OEM wheels due to their et48 offset and 9.5" width.

Size of spacers, if at all, depends on aftermarket wheels' offset. If aftermarket rear wheels' offset is mid/upper 20s to lower 30s, no spacers needed for flush fitment.

Are you familiar with the part numbers for the spacers both front & rears? I am going to be running a 285/35/19 rear instead of a 285/30/19. Do you think it will affect the fitment? I was planning on doing 20mm in the rears and am unsure what to do on the fronts.
Thanks in advance,

Thanks in advance,
For stock rear wheels, I would use H&R DRA 20mm (p/ns 40556654 or 40556654SW), 22mm (p/n 44556654) or max 25mm (p/n 50556651). 30mm will stick out. (285/35-19 is non issues, since I used identical diameter 285/30-20 with equivalent offsets to spacers as above). CLS OEM 27mm bolts are reused.

For stock front wheels, I would use H&R DR 15mm (p/n 30556659) which allows using OEM 45mm bolts from S/ML/GLE/GL/GLS/GLC/newCLS/E.

Okay, awesome thanks for the information. Will order some this summer. Do you use an OBD lowering module as well or do the spacers do enough?

For me, 1" taller outside diameter wheels/tires pus aggressive spacers, as above, was enough.
