Drilled/Sloted Rotors for CB7

[i'm the girl]

Btw, no one told me what "blanks" are?

Blanks are rotors with no drills or slots... like the ones that come stock on your car... most people who know better tend to shy away from blanks because they are prone to warping, as without drill holes or slots, they have no way to keep cool as you're braking

i heard that brembo doesnt make the slotted,drilled rotors, whenever you see them its an aftermarket company drilling them and selling them.

If you want a good setup that won't rust on you I would go with powerslot. Drilled rotors take away from the structural integrity of the rotor. I had a pair of brembo slotted/drilled and they were alright I guess, with the raybustes ceramic pads I saw a little bit better braking. I drove a 2001 jetta with a vr6, this car had the upgraded powerslot big brake kit (with caliper relocater) which is like 400 bucks for our car and the braking was awsome. Well, its basically about how much money you want to spend, the higher the price, the better the braking. I do have to say that brakes is a very overlooked thing by a lot of people. A lot of people are so concerned about making their car go fast and don't spend enough time trying to get it to stop fast as well.

And yet, there are still millions of them out there, doing there jobs, without warping.

not mine thats for sure this thread reminds me of how badly i need to change my brakes

i wasn't trying to say that blanks are BAD, just that they are more prone to warping because they can't, er, "aerate" like slotted or drilled, therefore tending to become hotter faster... and heat equals pliability equals warping

but obviously there are downsides to the others... i've heard just as much about strictly drilled rotors having structural issues and about strictly slotted rotors tearing up your brake pads, etc...

so i prefer drilled and slotted for "the best of both worlds" if you will, and the best company i know of that makes them exclusively is iRotors... and they're great

They say that drilled rotors rarely ever crack on a street car....

I've never heard anyone say their rotors cracked because of drilled rotors. The fact is that even beefy calipers like 4 piston Brembos don't apply extreme pressure to the rotor. Now if it was an F1 car with those monster calipers, then I'd believe it.

ive SEEN cracked rotors . . . it happens. anyways, brembo blanks are what your precious drilled and slotted rotors are made out of . . .

don't waste time on drilled/slott unless you really are going to go SCCA or track or whatever. brembo blanks, or regular decent blanks are good enough.

here's what i'm going to do, and i think this is the most cost effective for me.


-brembo blanks
-fluid (dot 3) either the valvoline or prestone brand
-axis metal masters
-good tires (not sure yet)

^^ that alone can get you much better stopping power

*optional stuff
-new MC if necessary
-new lines

It's not stopping power we're talking bout, it how to keep the brake discs from warping....

never said they did. actually, most of any complaint i ever heard about drilled was warping; which is NOT something i can say from direct experience. this is just one of the things i have consistently heard in my own research.

my personal experience has been that i've had the best luck with the rotors i use now on our newer car, which leads me to want to use them on my cb7...

if i only ever drove to work and back and maybe a little farther once and a while for a little vacation or something - i'd stick with decent blanks because it is all necessity requires, but i don't just keep the car in town. really we all have our opinions on the matter, but it comes down to what suits you best for your situation

[FishyMan]

well why would someone wanna change their OE setup?? im guessing he/she wanted to upgrade their brakes to 'possibly' have better braking power, not necessarily to avoid warpping rotors?

if they warp, they warp, but i dont' think an OEM rotor replacement would equate to a warped rotor. but i guess the convo has become blanks being drilled, slotted etc etc.

i don't know if they make rotors in a shape, or they just DRILL a blank discs. but i think getting good blanks will be good enough, if u have the dough, go OEM. it SHOULDN"T warp, u can guarantee that honda makes it stuff with good quality..

now if u want to go w/ slooted/drilled or whatever, imho those have been put through stress, and again, i have had no direct experiences of them warping or crapping other than hearing people say they eat pads crazy durring auto cross, and what not.

[OnE eYe GuY]

Dont go with cross drilled or slotted. Cross drilled rotors just decrease the surface area that the pad can use. As for slotted, you actually wont create enough gas to efficiently use the slots, so again, your just decreasing valuable surface area.

Hey,

I know it's been awhile, but I've been terribly busy lately. Here's the thing, my current OEM rotors on a 160k CB7 are warped like shit...I'm looking to upgrade stopping power because I dropped an H22a in my car, and I need more stopping power. No, I dont do autocross, but I do drive fast sometimes and I would like better brakes all around, I think it's safer.

I'm leaning more towards the cross-drilled w/o slotted, not to sure if I can find some but I'm still looking for people's opinion/experiences. As of now, I've desided I dont want to do the big-brake kit, I dont have 1-2k just lying around, though a couple hundred shouldnt be a problem.

Thanks for the input.

Pads will probably make the biggest difference as far as stopping power, but the drilled/slotted rotors will help with brake fade. They dissipate heat better since they have ways for it to flow out. The only reason drilled rotors ever crack is if they are straight drilled through because the edges on the holes are flat, and with them getting really hot and pressure being put on it they will crack from there. If the drill holes are rounded off then that won't happen though. If nothing else drilled/slotted rotors will look better too. I plan on going with some, but I'll probably just buy them from ebay.

Go to lsdmotors.com, they got some for like 80-100 bucks a pair...
