So i go these brembo brakes on my accord, i just found out that they were 3K... WOW... anyways, i was also told that there are spacers in the calipers, well i dot know what size pads i can put on my brakes cause i need to get them changed. Can i just use any pad from checkers? i mean the the pads that are suppose to go on the stock accord? or does it have to be the type of pad for the rotor? im just confused and everyoine i talk to doesnt know what brembo brakes are....
