      Front Caliper = 44mm and 40mm

      Rear Caliper = 42mm and 38mm

      That’s what I have in all my records as well. I know for a fact that the Gen 3 and 4 calipers are a direct swap, because I have the gray Gen 3 calipers on my ’08 (the bright red clashed horribly with the Venom Red Metallic). I’m 99.9% certain the same basic caliper carried over to the Gen 5, with the exception of the carbon ceramic equipped ACRs.
