Thanks again for all your replies with specs and pics. Based on the feedback, I created a chart of the changes in offset from stock. I highlighted the Stock NB and WB offsets. Several posts from other threads said that the rear offsets from the WB are too much for a NB, so as I thought, the recommended offsets I received from one supplier are just too aggressive. It appears that the sweet spot is around +12mm Front, and +15mm Rear.

Nice work on the chart. For reference with the stock 991.1 Carrera wheels (8.5 and 11.0 widths) I ran 8mm front and 15mm rear spacers. The rears looked fine but I could have gone wider on the front.

Thanks. Your experience with the spacers would seem to support the +12mm Front and +15mm Rear sweet spot.

20x9 +45 with 5mm spacer (245/35)
20x11 +50 (295/30)
dropped on H&R sport with no rubbing, was debating to run 10mm in front.

thanks! I saw you’re running same spec with a 10mm in front, any issues with rubbing? Your fitment looks perfect.
