quick question on upper control arms

A new high end performance vehicle will come with high performance brakes which include drilled and slotted rotors. That additional expense of production isn't necessary for the typical passengers vehicle.
In many cases we can buy high performance brakes, drilled and slotted rotors and ceramic pads, for typical passengers vehicles from the internet vendors for about the same or less coin than a brick and mortar part store gets for basic OEM replacements. Our 2011 RAV4 is one example.
