What wheels would look good on my GT?

COBRA for sure.

thanks a lot, I was thinking of those

Totally agree. I had a "True Blue" Mustang like yours with the Cobra R's and they looked good, esp. fitted with 255/40 tires. However feel free to go a bit wider in the rears if you want.

i see cobra wheels on the gt all the time. if you want to blend in go for it. if you want to stand out do something different. yes they look good but why copy what everybody else does?

Cobra R's or Saleen rims in chrome. 275/40/17s or better

torque thrust american racing rims

Chrome cobra 17" look nice but I'd personally get them powder coated black then put a Badass exhaust so make it look and feel like a beast.
