Default Wheel offset and fitment question.

Hi guys. I was wondering if anyone could help with this question. I was looking to buy a set of additional wheels and tires for winter. Can I put narrow body wheels on my 2015 turbo S if I use a spacer in the rear. Here is the wheel info from sunset.
Size: Turbo/Turbo S (991) with 5 Lug Wheels
Front - 8.5" x 20" ET51 - 245/35 R20
Rear - 11" x 20" ET56 - 295/30 R20

Size: Carrera/Carrera S
Front - 8.5 x 20 ET51 - 245/35 ZR 20
Rear - 11 x 20 ET70 - 295/30 ZR 20

It looks to me like i could put a 14 mm spacer in the rear to make up the difference.

Is that correct?

Thanks

Correct. And a 10 mm spacer would probably be sufficient. Don't forget to get longer wheel bolts....

Having just done this dance but in reverse, where ET62 wheels stuck out too far on a narrow Carrera that came with ET76 wheels, yes, that should work—although some will warn against the use of a 14mm spacer. If you choose to use one, be sure it is hub centric and has a good plan when it comes to the lug bolts and/or studs. You're obviously golden on the front end.

Thanks,

So just go with a 10 mm spacer and lugs. Any good place to source the needed spacer and lugs?

I've used ECS for Audi parts, not Porsche parts, but they're well regarded
