I want to get a set of 19" wheels and want to see if it will still look good with stock suspension. I will eventually lower my car. If somebody could post a pic that would give me a pretty good idea.

 

Here you go !

 

That's looks awesome. I might not even lower it then. What size tires are those?

 

I should have mentioned that the SVTPP rims are 19" front, 20" rear.
I do not remember the tire sizes.
I sold those rims/tires and used the funds to buy the FRPP SVT version of that wheel in 19" x 9" with a set of 245/45/19" Continental Extreme Contact DW's.
IMHO the FRPP versions are more in keeping with the power level of my NA 07 GT.
The 2011 GT/CS rims have Hankook Ventus 245/45/19" tires.
I am sure that I could have done better performance wise with a different size of tire. But I am old, live in Metro Detroit and I am trying to maximize the sidewall.
I have not driven the car yet with the FRPP rims but I did take a quick photo that should give you some idea of how that tire size looks.

 

Is there any rubbing in the front with the 245/45/19 when turning the wheels?

 

None at all.

 

**** that setup looks very nice! I would love to get my hands on a set of those rims.

 

Thanks ! I do really like the rims.

 

I'm running 275/35-20s up front (same out back, I'm a square type of guy) and no rubbing. Lowered 1" or so.
With the right offset, you can do 285s in the front.

 

I will be getting the tsw nurburgring in gunmetal black. I want 19x9 all the way around but all of the websites say the widest in the front you can go is 19x8.5. I can't imagine that makes that much of a difference. Also either going with 245/40/19 or 255/40/19 all the way around.

 

My 20x9s fit fine in front, as do my GT500 18x9.5s, and those also with 275s. The offset is key in front to prevent rubbing, though. Roush fits 18x10s all the way around, as do the racing editions like 302R, etc.

255s all around is good for the Mustang, I wouldn't go narrower personally. I had 255/35-20s in a General UHP that wasn't too grippy but very quiet and comfy.
I really like the 275s, though, amazing grip -- if you like to slide the car a bunch, they're not the best. If you stay at a 35 series (well, for the 20s, it'd be 40 series for 19s, I believe) they're a bit taller overall and give a better ride, at the expense of slightly making the gearing taller.

 

Here are a couple of shots of my stock supsension 06 GT with 2010 19" GT rims. Tire size is the stock 245/45/19. I have no issues with rubbing.

 

What offset should I go with if I get 19x9 and 255/40/19 all the way around?

 

Just look at the stock size wheels (or the typical aftermarket ones like on TireRack) and see what they use, good starting point.

18 x 9.5 stock GT500 rim has a 45mm offset. 19 x 9 stock front SVTPP wheel has 40mm offset, the 19 x 10 has a 51mm offset. 19 x 10 track pack wheel has 48mm offset.

So generally 40mm or more for a 9 inch wide or larger wheel. Any less (so 24-40mm) will push the outer wheelface closer to the edge of the wheelwell.

Exactly what I was looking for. Thanks.

 

Got a chance during a break in the weather to take a better photo. These are the FRPP SVT 19" x 9" rims with 245/45/19 Continental Extreme Contact DW's.
