hi,i newbie on x5. Just bought my secondhand E53. My question is that i have a complete sets of brembo breaking system. 6 pot for front n 4 pot for rear, which i was suppose to install it on my 3 series e46 but unable to do so due to it is actually for m3 models. Mine was only a sedan 320i. So, i was thinking to install it into my X5..Does this possible without any modification?Hope to get some advice on this.RegardsGarry
