I've been doing some research lately to find a set of wheels that take advantage of the Cortex offset front struts. I've amassed enough info now on Weld RTS S71 wheels that I felt like it would be good to share, regardless of what suspension you have. I haven't seen the wider 18s on many/any Mustangs except on a Titan Motorsports car years ago. They look okay in the photo, but I think the hub cap looks ugly and ruins the look of the wheel. They're also running higher offsets than necessary. These are 18x9.5 and 18x10s.
The wheels start out as 3 separate pieces (inner/outer hoops and a center) that are welded together. They offer 3 wheel center options with varying levels of brake clearance, but we would all need the "high" pad for the front wheels. The picture above shows the medium pad wheel, which works with the Stoptech caliper--I don't know if factory Brembos will work with the medium pad, but they do work with the high pad (which, imo, is a nicer, more shapely looking wheel center). Here is a fitment guide
Then, I ran across an 18x10 et41 (a great offset for square fitment and different from the 18x10 on the grey mustang above) without the centercap and I did a double take. It looks pretty good! Now here's some good news. Beefcake racing sells this wheel in a skinny 18x5 for 2013-14 GT500s and it clears the big 6 piston caliper over the 15" rotor with. Some say it needs a 1/8-1/4" aka 3-7mm spacer, which is a little vague but not a big deal. The wheel centers are the same no matter what the width is. Below is an 18x10 et41 over the 370mm CTS-V/Camaro ZL1 brakes, which uses the same caliper as the 2013+ GT500, only it's mounted on a smaller rotor. No spacers needed on these setups.
I think this is a good option for those who want to fork out money for a forged, light weight wheel. You can find these Weld S71s for ~$2000 shipped in 18x10s if you hunt around, which is a great price considering what you're getting.
I can't find info on 18x10 weight, but 18x12s weigh 22 lbs. We can infer that 18x11s and 10s are lighter. I'll be putting in an order in over the next few days.
