...... I thought this was going to be a joke thread. As everyone else has said, it won't work. You could TRY a spacer of sorts but it would have to be an extremely large spacer and you would almost have to be running skinnies.
they definately wont fit...
I put 99GT brakes on the front of my car. And I think they are slightly larger than stock rotors. I had a hard time fitting 15" welds on the front...
I have seen plenty cobras with stock 13" brakes have them so dont tell me they want fit. I know you have to have a spacer but dont know where to get it. This is for drag race only with 15 x 4 wheels in the front
