Will Boss Laguna Seca wheels fit a 2019 GT PP1?

[car_designer]

I've got a 2019 Mustang GT with Performance Package 1 on order that will hopefully be delivered in late January or February. That time of year, the temperature here could be in the 0*C to -20*C range (32*F to -5*F).

From my previous Mustang, a 2013, I've got a set of 19"x9"Boss Laguna Seca wheels with 275/40/19 all-season tires all around.

Will these wheels fit my 2019? I don't think the tires should be an issue. I've tried searching here and other Mustang sources but haven't found a definitive answer.

If they will fit, I may get the dealer to swap them so that I can drive it home without causing issues with the Michelins. Once I get it home I'll be parking it until spring. In the spring, I may be taking it on a road trip south so the all-seasons could be useful for that too.

I too have a PP1 car and I want to run those exact same wheels. According to CJ pony parts they will clear the big brakes on a PP1 car, and according to Ford racing, they will clear the laguna seca brake upgrade on the S197's which are also a six piston brembo kit with 15" rotors just like we have. And you may want to get a new set of lug nuts for the S-550's in case they damage yours when they try to mount them. The old s-197 lugs will not fit, they used the old 1/2"-20 thread and the 550's use a 14mm x 1.50

And if you plan on running the laguna wheels long term, you will need a new set of tpms sensors, the 197's and the 550's used different frequencies and are not interchangeable

Thanks Mike for the reply. As of right now this is probably just a short term thing until warmer temperatures arrive, but once I see them on my new Mustang who knows!

Man those look really good. You might want to keep them on.

Thanks! That thought has crossed my mind.

It's been a year and guess what haven't come off yet? The Laguna Seca wheels just looked too good to swap back to the PP1 wheels this spring.
