drilled vs slotted rotors.. or neither

i got a good deal IMO 250$ for 4 brembo rotors and axxis ceramic padsMK3Brent said:
and another note to all that commented on the rotors. I'm still looking for facts here :-/... I just keep hearing "IMO", but i'm trying to form an oppinion from proven facts, rather than other oppinions. :dunno:
Wanna know what works BEST? take a look at any High Performance car sold today. They have the same issues as we do, stopping power, and anti fade, reliabilty, wear rates, liablity etc. go to a porsche dealer, maybe a ferrari dealer, cause what they run has got to be the best available not just some crap some friend of a friend who said his neighbor had this or that rotors and they did this or that. It's all pretty much common knowledge in the high performance world that makes cars today in 2006.
well, the reason i stated this thread is because i've heard this and that, such as
-slotted rotors wear on the brakes faster, and doesn't really serve a purpose, as moder pads don't create gas
- brakes w/ no holes or slots provide a greater surface area for the pad to make contact
stuff of that sort, but there was no factual information behind these statements
-slotted rotors wear on the brakes faster, and doesn't really serve a purpose, as moder pads don't create gas
- brakes w/ no holes or slots provide a greater surface area for the pad to make contact

Ill have a picture for you soon. A picture is worth 1000 words.
Facts, Go to a Mercedes/Porsche/Ferrari deaership(as stated). They do work better.
Brake cooling is VERY VERY important. Ill try to dig up some information for you on both inquiries.

thanks, simply put, like i said, i couldn't really ever find any good info, so i couldn't figure out if it was just a gimmick or actually an improvementHellsLegion said:

Hey! I bought a full brake kit from these guys also, but they're for my 3G. I got the drilled/slotted rotors, axxis metal master brake pads, and SS brake lines all the way around for 400 even.
Funny thing is, I bought my supra RIGHT after i paid for these. I have them here sitting under my comp desk EVERYTHING IS UNOPENED! If you guys know someone who has a 3G GT or GTS I'll sell these to them for 300 bucks!
BTW: The box they are in is fucking heavy!
Heres what the Porsche Lemans car uses:
Most rally cars I see use the same setup.
If thats what cars of those calibers are using I assume its a good thing.

most drilled rotors are for weight issues as well i thought. saving a few pounds on an other wise stock supra isnt worth it, to me.
also, of course theres no end all answer to what brakes are better. other wise wed all be running the same setupha.

stoptech made a fairly large writeup on the topic, weighing both the pros and cons of each setup and which one is better for the desired application.
going by that, it's slotted all the way for me.

Research the rotors you want and look for info heat dissipation and cracking.
I haven't decided what kind I'm getting yet so I'm still searching.

[cracks knuckles]
nope
that is not the reason they use them
They use cross drilling to save WEIGHT not to improve braking. Back in the 60's/70's the pads gassed out like hell. Now a days that is not an issue even in a race circuit. Also remember that RACE teams chuck the rotors after each and every race. Slotting was used to help with the gassing out the pads. Again now a days it is not needed. And anyway if you compare the crossdrilling density of a true race setup vs the looky loo crap that the street setups get it is not even close.

Proven to work in reducing weight and that is about it. Trade off. Lose weight lose longevity.
so the real answer is, unless you are willing to replace the rotors OFTEN then neither option is a good option. Brakes are an energy tank. It stores heat and disipates it. If it can not store heat that when you start getting warped rotors. Crossdrilling/slotting takes away MASS which in the brake system made of steel or iron you need to store heat!

ahh more interwebbar myths!
FYI Racing porche and Ferraris do not run now where near the same components as the racing cousins. Ceramic based brakes disk vs CF/CF or densely crossdrilled STEEL rotors (notice I did not say Iron like the street brethrens, rotational mass removal is king in racing).

lol se my above statements
Yellow 13 said:
very good
one thing they don't mention
The disk are STEEL not iron like the street cars
figgie, i've heard myths that powerslot rotors warp. any input on this?
i myself am running drilled/slotted brembos from driftmotion, anyone know if these were drilled or cast?
everything seems fine right now, i've had them on for about 8 months and they work great with the porterfield pads and lines.

I actually read that actual brake rotor warp is pretty much a myth and a misused term for a separate problem.Clip said:
I'd have to find that article though.
