why? i have a set of gts in the garage have not put them on yet? where do you want themeasured from? They interchange with the v-6 ones if that what you want to know
V6 calipers are different than the V8 ones, as are the rotors.
They WILL both bolt to a S197 spindle.
The V8 brakes will not clear the stock 16" V6 wheels.
There is also a slight dfference in early S197 and later LF brake hoses.
