What's up enthusiasts, name's Dom and I want to know if a certain wheel and tire package would fit a stock 2014 Stang.
I'm looking to purchase some Enkei 18x9.5 +38mm wheels with a set of 275/40R18 all 'round. Stock suspension and plan to add an aftermarket big brake kit. The attached photos are the items listed. I bought some rims and tires in the past and needless to say i didn't get the right size. Some help with fitment knowledge would be greatly appreciated. If i have to roll/pull/ or add flares to get a flush fit please let me know.
Thank you in advance.
You need to get wheels to fit Brembo's and those do not.
When Using a Wheel Site Punch in GT-500 as Your Model! I Personally know the Pain of Limited Wheel Choices on a Gt-500. Are You Sure You Need Big Brakes! Just a Thought!
yep, look for wheels that are listed for 2007-2009 GT500, or 2011-2014 GT with Brembo brake package ... those should fit
18 x 9.5 wheel with 275/40-18 tire should fit no problem, as long as the bolt circle, hub diameter, and offset are correct; and the listing for these cars covers the fitment
you might want to consider 19" wheels, tire selection seems to be a bit better in 19" these days ... you want to match the tire overall diameter to your original tire diameter, and you can look up all this information about the tires in Tire Rack on the "specs" tab
I know thru personal experience, as I have the OEM 2007-09 Shelby GT500 wheels in 18x9.5" paired with Firestone Firehawk Indy 500 tires in 275/40/18" on all 4 corners.. The Shelby GT500 also includes 14" Brembo brakes... Also keep in mind the Shelby GT500 wheels also have an offset of +45mm... Therefore, if your intention is to upgrade to larger brakes such as Brembo? the wheel offset will require between +42/45mm in order to have enough clearance with an 18x9.5" wheel size... Otherwise, you'll be required to add wheel spacers which I wouldn't feel very comfortable in recommending.. That being said, I would not recommend purchasing an 18x9.5" wheel size with anything less than +42mm offset, unless you intend on adding wheels spacers
In the meantime, here's a pic of my 2006 GT with the 2007-09 OEM Shelby GT500 wheels in 18x9.5" w/+45mm offset paired with the Firestone tires in 275/40/18" on all 4 corners... Also welcome aboard..

I think the later GT500 9.5" wide wheels had 42mm offset, which is not a big difference, just makes the wheels/tires stick out a hair more .... more offset effectively pulls the wheels in under the car, less shifts them outward.
To clear the big brake callipers, it is not just the offset that matters; the shape and design of the spokes is important. The spokes need to be out toward the edge of the wheel, not curled back inward like on a Bulllitt wheel. But any wheel that is listed to fit a GT500 or Brembo GT should clear the 4-piston Brembo brakes that were used on those cars.
Regarding lowering springs: air ride is not common on these cars; I guess you can do it, but few people on here will know about it. I would recommend regular old springs and struts/shocks. There are tons of options and it depends on what you want. I wanted a slight drop, just about 1" with moderate spring rates; I went with Steeda Sport springs and GT500 struts and shocks which were available cheap as take-offs when I did this. I later "upgraded" to FRPP "K" springs and Bilstein struts/shocks, but I think I liked the original setup better. There are MANY threads on here about this, browse or search the existing threads to get more info.
These are Boss 302S wheels on mine, 9X19 on the front with a 42 offset with 255/40 19's on it.
I also have 14" Brembos on the front and 13.8" 2013-14 GT500 rears.

Those Boss 302S wheels look absolutely perfect on your "13" S197 V6
Do you mean spoke to caliper or just diameter in general?
For the wheels you have up there the back side of the spokes would hit the Brembo brake caliper. There are 18" wheels that will clear the Brembos but the ones you posted would be right against the brakes before being tight on the hub. Like Kevin said you need to find wheels that will fit up to a 2012 GT500, a 2012-13 Boss 302 or a 2010-14 with Brembos.
Here is a video that will explain the situation. It is not specifically for Mustangs, more big brakes in general, but they have some great info in the first half of this video.
Try to avoid using spacers if you can (part of their suggested options). Just find wheels as suggested above.
