    UrS6 piston diamete ron the rear brake needed?

    Hey Mate,I need more infos about the piston diameter on the rear brake of UrS6 with

    269X20mm Rotor Disc.The reason I need the size of them because I'm planning to get

    the Cayenne Caliper on this coming new year.The one issue I'm concerning is about

    the Brake Bias.I have measured the front HP2 Calipers.it has 43mmX2 pistons.

    I need the size of the rear one for calculating the proportion of the piston space

    between front and rear.

    here's the infos for anyone who cares about the pistons diameter on Cayenne 6 pots

    Calipers...

    20 4873 45 38mm X2
    20 4872 43 34mm X2
    20 4872 41 30mm X2

    HP2 Caliper on UrS6 43mmX2

    from google searched found some guys said HP2 Caliper from B5 Chassis has

    38mmX2 ..

    How come they ended up in different piston size between C4 and B5 Chassis.i just need to dig them more..
