It is amusing to see people nitpick every single detail. BMW is offering an oem big brake kit and people are still complaining. Amazing really?!
How can someone's reality be either 4/2 piston system or ccb, I WANT NOTHING ELSE IN BETWEEN? Earth shattering news, larger calipers and rotors weigh more. Yes, people actually put big brake kits on cars. There might even be a huge big brake kit market out there, with majors brands involved(could be imagining that
). I was just trying to show were some of the new weight could be coming from. The vast majority is coming from performance upgrades, whether is be brakes, engine, cooling, etc.
