I think you may have heard talk on cross drilled rotors cracking, but that's not the case with RDA dimpled rotors.
Conventional cross drilled rotors are known prone to cracking under hard use e.g. track/circuit.
that is because a lot of materials are removed from the rotor.
RDA did not cross drilled the rotors but they blind drilled them, therefore the strength can be maintained.
Therefore it is called dimpled, not drilled. So they should be a lot stronger than conventional cross drilled.
But regardless what rotors you have, once you take your rotors to the track, that will void all warranties
of any parts. Regardless what material or whether it's plain or slotted,e t c.
