I beg to differ. You WILL notice a substantial difference in your brake BITE and much less brake fade(if any).pzengilowski said:The only reason to go with slotted rotors is because they look better.

I've noticed a vast improvement in braking from like 130mph to 60 where there is no fade and no warpage of rotors. I've had my stock rotors glowing red and the end result is loss of brakes and destroyed rotors. My cross-drilled brembos do not experience this and I've gotten them so hot that when stopped you can smell them and see smoke wafting up from the pads. I've have done some extremely hard autocross driving on them and as I mentioned before there is a vast improvement. For everday driving if you drive normally then I would say stock rotors are fine but if you do any type of.... "spirited" driving, you'll want some kind of rotor/pad upgrade. My next thoughts on brake upgrades is somehow manipulating that metal splash guard to capture air for cooling my brakes.So, I do not doubt that your new brakes are all that you say they are - it's just got little or nothing to do with slotting and drilling. Which, as I said at the start of this you should only do for the looks. In some cases, slotting/drilling if not done correctly not only causes premature pad wear, but can also reult in premature rotor failure due to stress cracks.
If you are just doing "Daily driving" and not driving with "enthusiasm" , Then yes, you may as well stick with your OEM rotors/pads unless you just want the look. But if you do encounter heavy braking in your driving, then you will feel a HUGE difference.pzengilowski said:Guys,
The principle behind slotting and cross drilling rotors is to allow for the venting of gasses that build up under extreme braking conditions that virtually none of us see in daily driving. Even in a panic stop, there simply isn't the buildup of gasses that this venting is designed to provide.
The OEM pads and rotors will not have as much bite and will "Fade" under heavy braking, Even when new. The OEM pads and rotors "settle in" after just about 2 days of normal driving, Unlike the Brembo's where you will not even feel the difference untill they are broken in(300-500 Miles).pzengilowski said:Guys,
But this would be true even if you just put on new stock rotors and pads - they'd provide better bite and stopping power than the ones you replaced.
ANd help prevent accidents....claus44 said:well, since you are focusing on street then let's just talk about street driving. When it rains, the slotted/X-drilled rotors also helps to expel water from the rotor surface. Enough said?
There is a significant braking advantage especially under high heat conditions. Since the X-Drilled or Slotted or X-Drilled&Slotted rotors are not BIG BRAKE UPGRADES for our Legends, it won't improve your mild braking response (rotors are cold), but once it heats up, the added holes, the added slots in addition to the already vented front rotor will decrease the chances of warping and allow the pads to have less heat wear.pzengilowski said:Reasonable to assume that the pads would wear faster - but this shouldn't be a significant difference.
