Switching to a squared setup, need help

16 GT PP


I want to switch to a squared setup for both Summer and Winter - I don't track this car and I live in the city in the Midwest. After the P Zeros wear out I'll switch to something more economical, but here's my plan until then and it should set me up to save money on tires in the long run. I just need to know, does it work?

Buying a set of GT PP takeoffs:

Summer Setup
Front: 19x9.5 - Pirelli P275/40ZR19 P Zero - 5mm spacer
Back: 19x9.5 - Pirelli P275/40ZR19 P Zero - no spacer


Winter Setup
Front: 19x9 - BRIDGESTONE BLIZZAK LM-32 P245/40R19 98V XL - No spacer
Back: 19x9 - BRIDGESTONE BLIZZAK LM-32 P245/40R19 98V XL - No spacer


Thoughts? I'm not sure if a 5mm spacer is enough. I've seen conflicting posts on multiple forums stating that the wheels clear. On top of that they mentioned >5mm spacer means it's lug centric instead of hub centric. I'm not sure what that means or why it matters.

5mm spacers

7mm spacers
2 Wheel Hubcentric Spacers for Ford 5x114 3mm 7mm Thick 70 5mm CB | eBay


10mm spacers
2 Wheel Hubcentric Spacers for Ford 5x114 3mm 10mm Thick 70 5mm CB | eBay

Do I need new studs regardless of spacer size? If so, which ones can I buy that are straight bolt on? Another forum member started talking about knurling and lost me
Quote:
Only one stud 6-10mm longer vs stock and will require dressing knurl on bench grinder.
Stock studs are 49.9mm with 0.625 knurl. cut n paste from phone notes:
610-435 57.94mm 0.628knurl
610-509 73.4mm 0.627knurl
610-437 76mm 0.628knurl
610-530 78mm 0.626knurl
610-333 90.5mm 0.625knurl
