Traced article on "trackmustangonline.com". Interesting thread on potential front brake upgrade for S197/GT500 (07). Part#'s. rotors of 2014 GT550 15"- DR3Z-1125-A, Caliper's of 2017+GT350R - six piston Brembos-FR3Z-2B120-G and FR3Z-2B121-F, and supporting hardware retainer clips, hoses, pads etc. Anyone try this? Says calipers will bolt to existing bracket of 07 GT500. Could do this for about $1400. Now pushing about 620rwhp and on this heavy car an upgrade of this scale would be welcome. Tob got any thoughts
