306 rotors and calipers are a direct fit onto a 205 Si. The rotors are the same diameter, 247mm. However the 306 rotors are ventilated and thicker. 306 calipers are bigger than Si and have greater pad area.
Si rotors 3.09 kg, calipers 2.6 kg.
306 rotors and calipers are substantially heavier.
Fitting is quick and easy with the hardest part being getting the rotor retaining screws out.
