Just wondering whats the difference? I hear the dimple drilled rotors is better because the rotor is less prone to cracking. But on the other hand I would think the drilled thru rotor would have a much cooler temp vs the dimple. Which one is better?

My powerstop dimple drilled rotors cracked after the first few hard stops

If you are talking about race concepts rotors I highly recommend them, great product, they use Brembo blanks but there dimpling idea makes a lot of sense, all of the cross drilled brembos I have seen that were driven hard crack at the holes, dimpling allows the gas to escape somewhere while still maintaining the strength of the rotor.
if you do a groupbuy they cost 50 bucks each, how do you beat that, I love my Raceconcepts rotors, great service also. (please sponsor me, woood!!!)
