Reasonably priced BIG BRAKE alternative that fits in a 15” wheel

I know this is likely the biggest kick in the teeth for anyone on a budget. My solution gives looks, function and fits in a 15” wheel as a bonus..
specs:
Wilwood D52 twin piston caliper, ya it’s GM based but hate later, it looks like nothing the general ever stuck on anything
Rotor: Chrysler Cordoba 12” rotor (11.75”) close enough lol
Spindle: Mopar disc brake
Steel plate: 3/8” thick
