Looking into some HRE S104 wheels. Wondering if these will fit my 2013 S6. Can anyone let me know if these will fit? I already have spacers (12F/15R) but not sure if I'll need them with these offsets. Thoughts?

FRONT: 20x9.5 ET 28
REAR: 20x11 ET 33

Won't fit. Ideal fitments are 9" with a 35mm offset or 9.5" with a 40mm offset.

Do a forum search for HRE. Lots of guys running various configurations. I would be careful about running different widths front versus rear.

I am personally running P44SC in a 20 x 9.5 with ET 47 offset to most closely match the OEM wheel offset.

It's going to depend on the tires/tread size you're running as well.

My P44SCs are 21x9.5" ET40 with 265/30/21 Michelin Pilot Super Sports. I went with the same offset all around so I can rotate the wheels/tires.

I also recently added 6mm spacers in the rear, and the fitment is now flush (pretty much right to the fender edge). I just received 4mm spacers to add to the front wheels.

I've seen quite a disparity on this as well. I am also running PSS's but I am running a 275 tire on mine. I see other guys who run as narrow as 255's on their HRE's.

Yeah, there's really no set rule as long as the sizing is within the range of approved widths from the tire manufacturer. Personally, I like more square sidewalls (and the extra rim protection). If the Michelins came in 275/30/21, I definitely would have gone that route!
