No.....Cobra rotors are 13.0" and the GT’s are 10.8”. You'd need the appropriate caliper, brackets and hardware in order to make them work with your GT.
You can get Cobra front brake conversions for as little as $400 now if you look around a little.
haha okay, cobra and the bullitt calipers are the same, so buy which ever is more appealing to you. and be prepared to pay out of the ass for shipping. I paid $57.13 to ship the 16x16x16 box that weighs 62 lbs to hawthorne california.
