Beach Girl Black And White Clipart at Xavier Mccomas blog DBA 08 13 BMW M3 E90 E92 E93 Front Slotted Street Series Rotor. The T2 slot design features precise CNC machined bi symmetrical slots, resulting in a quieter, more responsive and smoother brake pedal feel. The T2 slot increases the number of exit points, allowing friction dust and gases to escape and enhancing the pad bite. DBA's revolutionary universal slot design also eliminates the need for separate left and right slot designs seen in traditional rotor designs. We recommend the T2 slot design for more intensive braking applications. This Part Fits: Year Make Model Submodel 2011 BMW 1 Series M Base 2008 2009,2011 2012 BMW M3 Base
