The Data in the image is correct. Although I agree in most cars the fronts are larger, due to the handbrake shoes in the rears, sometimes the rears are larger in passenger cars as is the case here until you get to the Territory Turbo. I have contacted the tech at PBR and he is looking into it for me. Interestingly he mentioned a 6 pot monoblock setup the are about to release which would be awesome but pricey!
