I purchased a set of callipers from a supercharged l494 to upgrade the standard non brembo’s on my 3.0.
Knew the fronts was the 6 pots but never paid much attention to the rears and was expecting a smaller shiny red version of the fronts but they look identical to my standard rears just with a sad light dusting of red paint. Is this the case?[/quote]

My 5.0 Supercharged has Brembo. I can confirm on mine it is one piston caliper in the rear.

So yes rear calipers are no different throughout the models
