I plan on going with 315/35/20 rear tires with 20x10 PP1 Replicas on the back and the OEM pp1 rears on the front. Wondering if anyone knows what spacers are needed for this setup? Any tips or advice would be appreciated.

OEM PP1 rears need a 5mm spacer to be used on the front. Get a hubcentric one, the generic ones are not confidence inspiring.

Thanks, do you have a recommended brand? I found some on amazon but I dont think they have the correct hub bore, but I did find some on Ebay that should work.

For some reason the shop that was going to put my rears on the front said it wouldnt fit with a 5mm spacer and not even with a 10mm spacer...

It was a ford dealer though so IDK if they were bullshitting and/or just wrong, but they just kept the 19x9's on the front and put 1 spacer there.

I tried putting the OEM rear pp1 wheels 19x9.5 with 275 40 19's on the front with a 5 mm spacer and can confirm they do rub the strut, atleast when the wheel is fully extended and the car is jacked up. Not sure if this is a new fitment problem for the 2018+ or if it also affected earlier mustangs. Just kept my stock fronts on for now with the 5mm spacer but I wish they fit a bit more flush with the fenders.

I thought PP1 rears were like +52 offset. If so I can see why the 5mm spacer isn't enough.

5mm is definitely not enough. I tried it with 9.5 rear wheels and 275/40/19 continental extremecontact sport, and it was just rubbing slightly, so I understand how some people get away with it using tires with a slimmer side wall.

FPRS mustangs uses 8mm spacers and arp studs on all four corners, and they run 285/35/19 gforce sport comp2 tires with no problem, but the bottom line is that you need new studs to fit the PP rear wheels up front. You can definitely use bolt on spacers but I hate bolt-on spacers personally.
