why are you hitting the brakes so hard? Sounds like you do it a lot, learn to drive....And yes you are describing abs brakes.

 

Also, I'm just going to throw it out there that it's extremely hard to find a place willing to turn a drilled or slotted rotor. They tend to chew up the teeth on the lathe, so most shops won't do it.

But if the car is 100% a street car and it won't see any track duty (and you drive like a normal person), the only reason to get drilled and slotted rotors would be the aesthetics.

And people that remember my civic might remember this little detail:


I had cross-drilled and slotted rotors on all four corners; I got them because I needed new rotors anyway and I liked the look. Rest assured, I felt no difference between those rotors and blanks.

Again, as far as controlling heat, get larger rotors. Larger rotors = more surface area = better heat dissipation. End of story.

 

well i drive fine. it happened once and freaked me out. thought something was wrong. if thats the way they are, then so be it. just curiuos.

 

I would eliminate drilled as a choice, simply because you will almost certainly lose braking effectiveness, especially with the drilled and slotted combo. The total braking surface area is reduced too much when we're talking OEM diameter rotors.

Now if you use your Civic infrequently or for very short trips, then slotted rotors are prefereable over blanks. While pads don't glaze as much as they used to, I've found that they still lose their "grab" over many years. Slotted rotors keep the pads fresh and parallel to the rotors, maintaining that "like-new" feeling for as long as the pads last.

If you are driving 12,000 per year and want to keep pad expenditure costs down, then blanks are the way to go. By the way, the ultimate slotted rotors are Cryo-treated. They will probably last longer than your ownership of your car does and should never need to be turned, as they will never warp or accumulate a buildup of uneven pad deposits.
So, if you want to buy rotors and not ever have to worry about replacing or having them machined, get Cryo slotted or blanks. If you keep your car for a while, the money you spend up-front will be well worth it.

 

thanks. i really appreciate that. what brand do you prefer for cryo slotted rotors. i believe the moeny upfront wioll be worth it in the end.
