Great work on the caliper painting! The prep work you did will pay off, as the paint will stay on the calipers and their brackets for just about ever!
next step for you is to buy the GT rotors and GT caliper brackets. This allows you to have the larger front rotors as the GT's do (back rotors on the V6 and GT's are the same). The front calipers are the same also with the GT's and V6.
You'd then only have to paint the new GT caliper bracket after installing it and the GT rotors.
Look at Roush's web site (Or Ebay
, they sell low mileage GT rotor take offs, the front caliper brackets, and calipers (even though you don't need the calipers) for cheap.
