Slotted Brake Rotor Question

Slotted Brake Rotor Question
I recently changed my warped OEM rotors for drilled & slotted rotors - still using the original pads. Since I've never had drilled & slotted rotors on any of my previous cars I'm not sure how they should feel when braking. Right now when I brake from 70 mph, or so, they seem to be rough not smooth like the solid rotor. I think the slots rubbing against the pad is causing the roughness. Is this natural?
Thanks.

They are "rough" when compared to the smooth solid rotor. Especially if they're slotted AND drilled. You're feeling parts of the pad moving in and out of the holes/slots.

i have slotted rotors... and you do feel and hear a rough sound coming from them.
btw, when replacing rotors, you should also replace the pads. You want the pads to conform to the new rotor's surface. Using the old pads will not work, so that may be adding to the noise that you hear.

that's odd, pretty much everybody that I know alwasys replaces the pads when the rotors are changed.
the only exception is when the rotors get resurfaced. Which is kind of like replacing the rotors (new surface to conform to).

I didn't experience roughness on my slotted discs on my 95 Accord, and I actually lasted them for a VERY long time.
But maybe it's different on the TSX.
Maybe it also varies from one company to another. I had Powerstops with Axxis Metal Masters, granted they were not the most aggressive setup, but still they offered a good compromise of enhanced performance and durability.

You won't see any performance improvement from slotted or drilled discs unless you plan on taking the car to the track. It simply isn't possible to drive on the street (legally, or even close to legally) in a manor that will cause the brakes to reach temperature. The rotors simply aren't going to get hot enough to take advantage of the additional heat disapation. The holes and slots are designed to allow gases from your brake pads to escape under very high heat. Your buddies might think they look cool, but you won't stop any shorter. Better quality pads will provide more stopping power, but the drilled rotors won't help and will cost more. Cheap drilled rotors are actually worse than solid rotors because the structural integrity of the rotor is compromised by all the drill holes. My $.02

It is clear, in a normal conduction they are not necessary, but apart from that aesthetically are very well, the yield is superior overalls in wet and to high speed.
I usually run as fan in circuit and their effectiveness is noticed.
