Aftermarket winter wheel offset questionn

[Steverin06]

Just signed a lease for a ‘25 GTS. It’s riding in 21s and I’d like to go down to 20” soon for the upcoming Utah winter. I’ll post pictures when it’s delivered, I am super pumped about it!

I found some wheels with the correct bolt pattern and hub, but the offsets are different from stock.

I’m curious in y’all’s thoughts on these wheels, and also on slightly narrow than OEM winter tire setup with it.

• Front Size: 20x9
• Rear Size: 20x10
• Offset: Front 46 / Rear 50

From reading online about people using spacers, and from what ChatGPT is saying, these offsets may actually be better than stock for winter.

this is what chat said:

• Narrower is actually good for winter → your rears would go from 11J (OEM) to 10J. That helps cut through slush/snow and improves traction in winter conditions.
• Offset difference (ET46 vs ET54 front, ET50 vs ET60 rear) → they’ll sit ~8–10 mm further outward. For winter, this is usually not a problem, and actually helps avoid rubbing on the inside with chains or buildup.
• Tire sizing: You’d probably run something like 245/45R20 (front) and 275/40R20 (rear), which fits these widths well and matches Porsche’s recommended winter sizes.

Sounds absolutely fine.
Stock recommended on rear is actually 285/40R20 which you should probably use otherwise rear height will be 4mm lower than front and wheel tyre combo lower than front so wheels will spin faster than supposed to compared to front. Plus nice to know you've stuck to official tyre sizes.
Wheel sizes/widths will be fine & yes lower offsets will push wheels out slightly for better appearance.
