no good at photo shop but yes you need to show those calipers.

i am worried about the 17" for calipers and since i would like 345mm rotor and don't you want those disc for the v8 in the future

i like the thought of the price of the tires but i think 18's in your favorite rim would be ideal combo to run and give you a nice wide footprint to grip and spread all the weight of the v8 up front.
