I currently have the base kit front brakes. I want to upgrade them, but I want to use something that I can get at a local parts store if needed. Wilwoods that FFR sell are out.

Are these brakes mustang based? Like, if I get bigger rotors and calipers that would be an upgrade on a mustang gt from whatever year, would that work (aka, if they are 2000-2004 based, would aftermarket upgrades to those years work?). And if so, what year range and model are they from? Or am i completely off base?

My rears are already 2000-04 GT brakes so I’ll toss some slotted or drilled rotors on and call those done. I do want to upgrade to much larger drilled or slotted up from with calipers to match.
