So upgrading to the dimpled-slotted rotors is not worthy, since I don't use my car for competition
How about much simpler set of just slotted rotors at front with the stock calipers
I've heard of some cheaper aftermarket drilled or slotted rotors cracking. My vote is still on the GT oem rotor upgrade. The difference may not be massive, but for $225 you won't at all feel like you threw away your money.
