Default Are slotted/drilled rotors woth it?

its time for new rotors and pads. I understand that slotted/drilled rotors dissipate heat better - meaning I can brake later in my approach of a turn and ride them harder then OEM's right? or are they just as easy to "burn" as the OEM rotors?

Slotted/Drilled Rotors?

Edit: currently all stock - to the bone.

this is up to you if you have the money go for it but remember rotors wear and drilled and slotted rotors cost more. op if the car in your avatar is yours you should do a big break upgrade (civic sedan ex, or 90-93 integra upgrade)

If you are a road racer that runs 30 hot laps in a row, I'm good with slotted only. Drilled just creates good places for the rotor to break. For DD, autocross, or drag, stock is fine.

Thanks. Yeah, it's not a track car, so I would probably be wasting my money. For that I need different knuckles right? does that mean new CVs and other stuff like control arms? also I'm fine with the stock wheels and tires for now, will I need bigger rims for bigger brakes?

I would swap to da hubs and brakes. it doesnt cost much and the increase in braking is more over slotted/drilled stock rotors.
edit++ You will need atleast 15'' rims to run da brakes.

dissipating heat is not the point of slotted rotors. they are not heat sinks. they just evacuate the brake pad material and any gases between the pad and rotor.

no, they are not worth it. just for looks for all intents and purposes on your street driven car.

Really? i wasn't aware that all DA integras came with 15in wheels.

Every set of 14's ive ever tried(3 or 4) have fit on DA brakes, some do require a little spacing though.

You can try upgrading to Steel braided lines, MC, and using better fluid.

I was thinking the same thing as garageEF..
I have 14's on my car now with DA brakes all the way around...
A much better increase compared to stock though...

As stated, slotted only, and only IF you plan on tracking the car. Basically if you had to ask this question, there is NO reason for you to use anything but blanks.

When I was young and dumb I have the drilled/slotted Brembo rotors. I didn't stop better with them and cracked them on track. I run only blanks now less money better stopping. Amazing what you can learn over the years.

WOW, thanks everyone, this site is AMAZING! Its only a Daily but, like most people, I enjoy spirited driving.
Anyways, looks like I'll be replacing with OEM blanks since my tires have plenty of tread left and my aftermarket suspension is a long ways away.
Are ceramic pads the best bang for my buck? I'm willing to pay more for longer lasting pads, but I don't want to pay for a "Brand" on the box.

I won't use drilled rotors, because I know they crack, however, slotted rotors in applications where you are hot lapping, slotted rotors help by dissipating gases and keep the pads from glazing over. There are many sources where you can learn about the pros and cons of the different style rotors and pads. But with technologically advanced brake pads, there is little to no need for anything else except blanks.

Just upgrade to new stock lines. Steel braded are bling only...

Me? LMAO bone stock D15 ~ 90hp to the flywheel. no real POWER, just playing around for now
B18B someyear.

So ceramic pads with blank rotors, new lines is probably a good idea too. When I get 14/15" rims, and the pads i put on now go bad, I will prolly do the big brake upgrade.

Thanks Everyone

hrm.. well **** a shingle.. thought they are 15's.. OH well.. but I did try a set of 14's and they didnt fit.. I guess really with 14;s you have to pay more attention then i did while writing my response hahahaha.. 15s fit no problem

EDIT
oh and as for pads... Commercially available "blended" ceramics are for less dust better in wet conditions and for more moderate/ heavey braking.
Standard organic pads provide a higher friction rate. better stopping power, but yield limited heavy braking an poor wet weather braking.
Semi metallic is really the middle ground for pads and perform good overall.. Be aware of some pads as they have the potential of being too harsh for rotors and can chew them up pretty good. dont fall for the sales pitches.. stock replacements are good for DD and mild spiriting.

Slotted and drilled? not worth it at all... not on a street car. not even on 90% of track cars. you are doing something wrong if you are generating that much heat on the street.

Slots = pad wear, thinner metal for cracking, less metal for heat absorbtion
Drilled = used to be for venting pad gasses (we dont use pads that generate gasses anymore, generally), more areas for cracks to start, less metal for heat absorbtion

I run regular old vented (but solid) rotors and Carbotech XP9s on track... i can overheat the brakes that way, but swapping back to street pads and even goofing off i dont heat up the brakes AT ALL on the street.

Im with Clipse..
I run Hawk pads, Brembo slotted rotors, Steel Braided Lines &
NHT Calipers with a better boot/seal kit..
My car stops SO much better than stock.

i believe it! because you upgraded your pads and replaced the calipers and maintained the system. im sure its better than what was there before. but its not because of the slotted rotors...

ppl just need to pay more attention to their brakes, AS IS. theyll get much better performance alone.

I think SS brake lines are a good upgrade, and I love mine. They are a lot more responsive and they get rid of the spongy brake pedal feel. They don't expand like the stock lines do. Just my 2 cents

Since everyone had an opinion about almost every brake
part I figured i'd say what I have. But over all. Go big or go home.. lol

edit: before I had it all upgraded, I just had the rotors and it was a difference. :-)
