I'll update specs on Monday - I called HRE yesterday to update this (as I was driving past them in San Diego) and the sales person actually told me they have no wheels for the G20 - I politely told them they did but he wouldn't budge....sooo I'll try again Monday and get someone else on the line our fitment is obviously something new to them
Sooooo in that I am in the market as well I figured I'd dig in a bit and share what I found out, this should help.....the FF01's only come in:
-20 x 9: et35
-20 x 9: et25
-20 x 10.5: et35
HRE claims that the 20 x 10.5 et is too aggressive for the rear which means with the 20" only a square setup would work (9" wide Front and Rear).
That said the 19" options are pretty good at
-19 x 8.5: et25
-19 x 9.5: et42
Now we can compare that to a stock 19" 792M wheel with spacers (Like some here are running to get things flush)
-19 x 8: et27 with 15 spacer = et: 12
-19 x8.5: et40 with 13 spacer = et: 27
So punching the aforementioned into a wheel offset calculator, when comparing a oem 792 "flush" setup achieved with spacers vs the HRE 19" offering we get the following:
-Front inner clearance would be: 19mm less
-Front outer position would retract by: 7mm
-Rear inner clearance would be: 28mm less
-Rear outer position would retract by: 2mm
If I were to run this setup (which I may) I would run a 5mm spacer in the front on HRE FF01's which would give me a fitment very close to flush front and rear.
For reference here are the 792M wheels with spacers that I used as a starting point. Remember the HRE's (with a 5mm spacer in front) would be 2mm Front & Rear more tucked (however the overall wheel width would be wider which is always nice) vs these pictures - which would be perfect for me.

This is incredibly helpful Chenry, thank you!
How does the calculation to achieve a flush look change if we use 19x9 in front? I’m aware these sizes might not be available in the FF01, but trying to wrap my head around these fitment calculations in case I explore other wheels and sizes.
