Bianchito,
The fronts I beleive are Maserati, the rears I'm not so sure of. Many people choose to upgrade to the Porterfield pads and feedback is generally positive on this upgrade.
The rears are product #GD-535 and they are $80.
Find them at www.porterfield-brakes.com and if you do order remember to ask them to weld on the locator tab.
