wheel fitment question

[Santi0105]

i have a 2015 mustang and i want to run 19x11 +22 offset with 275/35/19 wheels

i have a friend that has the same mustang that i have and he is running 20x10.5 +35 offset on 265/35/20 and his fitment is flush in the rear but in the front he added a half inch mm to clear the brakes. he is also lowered in lowering springs and i bought the same ones, just lowering springs no camber bolt or anything, the camber showed in the pictures below if natually given by the lowering springs
here are some pics of his fitment

if i run the 19x11 +22 offset it says that my wheel will poke 14.4mm more than his such is about half of an inch, so i'm guessing that if he added a spacer that is half an inch to clear his brakes and my wheels will poke half an inch but since i don't need the spacer because i don't have the brembos the fitment would be the same as his, the only difference noticiable would be in the rear wheels.

the top is his specs and bottom are mines

orange is his fitment and green is mine

if my calculations are right i would be fine in the front it would be about the same fitment as him maybe will poke 2mm more but in the back i will notice the half an inch poke.

please let me know what you think

thank you

Your friends car has a nice dialed in stance. You wanna go a wider rim by +1/2 inch with +22 offset on all the corners?

so pretty much his front fitment is dialed but because he added and 1/2 inch spacer tk clear the fitment , i don't need a spacer and my wheel would poke out 14.4mm more than his wheel but since i don't need a spacer i should have the same fitment as his but in the rear i will actually notice the poke of the 14.4mm since he is running no spacer you get what i mean ?

You think that looks good. Everyone is right mustangs are becoming the new Honda

Yes, I understand the additional 1/2 " (.567") poke in the rear. I don't think there's an issue so long as you've got clearance at ride height then factor suspension movement under load conditions. The tires at the sizes you're planning to use will look ok I think...maybe even a slight "stretched" look on your wider rims but I don't see that as a take-away. (You're friends car has that "look" - I get it)

I took my factory installed Sport Cup 2's off with factory 10 1/2 front and 11 inch rear wheels for track use only and I'm running the Ford Performance wheels (Same sizes) on same size 305-30ZR19 PS4S tires and (all factory offsets on these wheels - no spacers) with factory set cambers all round and I have roughly 3/4" poke in fronts with about 3/8" (just tire sidewall only, not the rim) in the rears.

But this is a 2020 performance level 2. I think 2017 to 2021 suspension dimensions are all fairly the same... I don't know about the earlier S550s. Others here are far more knowledgeable than me and as you know we Mustangers have stuffed all kinds of shit under these cars. Every change in suspensions and/or wheels creates a myriad of geometries that have to be identified than optimized for whatever you're planning on doing or trying to accomplish. But yeah, sorry to go long here... I think you're gonna be ok.

So many want to stuff the biggest, fattest wheel/tire combo possible with the best lowered stance I guess.

I'm far more interested in going around a track as fast as my abilities allow. Most of the cars I track have far more capabilities than my driving skills.... and I've been driving for more than 50 years! If that means I need more clearances to go faster on any given road course than I do it and I focus more on having the best and biggest brakes and pad combinations I can physically employ.

That is horrible for fitment. They will stick way out and tires will be stretched to the MAX!

11” ET22 will be about an inch of poke past the normal “flush” setup we most commonly see with 11” rears. I wouldn’t do it, it will look like it doesn’t fit the car w/o fender flares. Also 275 is quite narrow for 11s
