Rotors originally were looking at the BMW Performance slotted & dimpled rotors, but recently was made aware that lighter Z4 35is ones could be mounted directly.
I would like to verify is this is correct.
Thank you in advance.

Z4 35is rotors are not lighter than 135i rotors. The construction is the same, steel rotors riveted to aluminum hats, but the the 335i rotors are larger in diameter and thicker than those of the 135i and of an unknown (to me) difference in offset.
