mine are slotted and drilled

Do you track your car alot?

[Underground_Killah]

um....

how do i say this....

nope.

only track here is a 1/8th and i don't see my car tearing up the 15's ever again.

Then out of curiosity, why did you go with different pads. The whole point of the specialized pads is to reduce fade, and cool faster under heavy breaking applications (tracking, not 1/4 mile runs). If you are expieriencing heavy fade on the streets, and need to worry about cooling...then you really need to rethink the way you drive. Unless your car runs elevens or faster, you are fine with your stock pads and rotors, and might only need to look at the lines.

well first off, i read the book on rotors (thanks hyde for the suggestion) and it even said it would help with braking at high speeds (80+)

but that wasn't why i bought them. see i could be all bad ass and go "yea cause i'm gonna race this thing till the wheels fall off at the track" but i'm not.

When i first got the car, the brake rotors were in decent shape, my cousin lied on him doing a brake job, so i assumed the pads were fine. eventually me, not being very experienced at the time worried on the body work while the pads became nothing and metal was digging into metal. eventaully there was a gap on the rotor like 1/8" thick and it was time to replace the rotors. Regular rotors from infiniti are freaking expensive. I was not about to replace with that because i'm a college student. i saw the slotted and drilled from speedy dynamic and they were cheaper than the oem's. since then, my braking is better, and i like how they look with the 17''s. i remember that night when i first put them on a jackass in a ranger was drunk driving and swirved right in front of me and hit his brakes.... i stomped on mine and had i had the oem's on at the time.... i'd be out of a car. i stopped on a dime and ever since then have recommended them to everybody.

I'm on my factory pads and rotors, have done multiple fast stops from 100+ (not like, slam on the brakes, but hit them hard enough to slow me down to legal limits way fast), and once or twice a week, I go on some hella twisty backroads where having good breaks are a must.

Sloted rotors, big brake kits, all that stuff are designed for tracks, where you do heavy amounts of brakeing for extended periods of time. They work best when heated up to operating temperatures, and are designed to help reduce fade (it takes more than slotted or drilled rotor to just reduce fade) from the pads and rotors heating up. I guarentee you that if you had good condition OEM rotors (not the rat ones you had on their), you would have been able to stop just as fast as you would have with cross drilled or slotted or big brakes or whatever.

I can see how you think they are better because you had shit brakes when you got the car, but if you had new OEM brakes, it would have been just as good. On the street, unless you are doing some sorta Need For Speed Underground or Most Wanted racing where you do laps through downtown while running from the cops that get hella beat up and your only damage is a cracked windshield, then yeah, you might need slotted or cross drilled or big brake rotors and pads and what not.

I run from the cops everyday. And I've got drum brakes out back.

Holla at ya boi!

He HAD OEM rotors before.....That's usually what comes on the car.

I've driven too many cars to count, but I'll example a couple 240's. I've got two buddies, both with S13's. One has OEM rotors and ceramic pads, the other has the same pads but cross drilled rotors. I cannot stand driving the OEM rotors, they feel waaay too mushy and it take forever to stop, like you're hauling a trailer. The cross drilled? MUCH more responsive! Now, I know of an S14 with drilled and slotted rotors, but his car doesn't count, as it's a fully built drift car.

Maybe I just have good brakes, but my brakes never feel mushy or week, and I've never had a problem with them.

Differs from car to car.

My Escort has solid brakes, but if I nail them at 90mph on the off-ramp, I'll be damned if they dont fade.

The one with cross-drilled rotors, did he get bigger rotors or were they the same size as the OEM rotors?

Mushy pedal feel is caused by boiling brake fluid, expanding lines, and on rare occasions the master cylinder. If it were your rotors causing it then you would smell them. Most OEM rotors are sufficient to stop the car, even from high speed.

The GTC has the OEM rotors with crummy pads and it still stops on a dime, even from high speed. All I am changing is the fluid, flex lines (ss lines), Hawk pads, and I'm painting the calipers red.

You will see more from changing your fluid, changing your flex lines to ss lines, and better performance pads.

My brakes are stock.

This has always been the school of thought I was in...its not your rotors, its the pads, lines, and fluid that really help performance

There is a guy in Texas with a 1000whp/1000ftlbs tq Supra with stock brakes.

[Mr. Luos]

I prefer stock.
Even if I road raced occasionally, I would probably still have the stock brakes.

The only problem I have had is when they get REALLY hot they fade a little, but nothing dangerous.
I like having the entire disc be a contact area for the pad. No slots, no holes drilled. The front clip of the car keeps the brakes cool for the most part.

Ya know.....I really don't know if they were bigger or not. Honestly did not pay any attention. The S14, yes, but that's a different beast.

I'll consider some better fluid on my stock brakes, then look into some better lines. I know my brakes have the ablity to lock up my tires, but I have to stand on them, lifting myself off the seat, in order to do so.
