Aftermarket rotors, suggestions? Options

[Akimbo]

I'm looking to buy some aftermarket rotors. Anyone know where to find good ones? Maybe some Brembo ones?

[shin]

cross drilled? slotted? cross drilled & slotted? or stock replacements?

[playr158]

got a set of brembo slotted if your interested

[LewFX]

how much for the brembo slotted?

[Akimbo]

Looking to go with some good looking, good braking, slotted/drilled, or any combination thereof. Playr, are they front and back for a GT?

Beware x drilled rotors. They were originally designed for race cars to reduce unsprung weight. Due to the holes, they are prone to cracking, especially if the holes are drilled after the casting has been done - often the case for most aftermarket applications.
Slotted rotors are a thow back to days when asbestos was used in pads. Due to a build of of gases as a result of the pad resins heating up. The grooves allowed the gas to 'escape' as it would usually create a 'barrier' between pad and rotor which lead to brake fade. Grooved rotors do work well, but do tend to acellerate pad wear.

ive heard good things about www.irotors.com

[ghostdog]

all true and good points. but you are forgetting the most important part .. they look cool

just need something to improve braking...

In that case, stay with stock rotors and get some decent aftermarket pads. I'd recommend Mintex 1144 pads for normal road use or 1155s if you want to push the car a bit harder. And also put in some decent brake fluid. Standard road use stuff like DOT 4 etc isn';t up to much when you start getting serious heat in the brakes as it has a relatively low boiling point. I personally use Elf HTX brake fluid which I also use in my rally car. Not had brake fade as a result of boiling fluid yet - and the car does get pushed hard. See the vids I posted a while back

Brembo doesn't make slotted rotors for our cars.

Anyway,
I'd get the OEM replacment Brembos from NopiOnline.com. They've got good pricing and they're actual Brembo rotors, and they're not slotted or cross-drilled so you'll have longer brake pad life and better braking performance(until the rotors get too hot, at which point one of the cross-drilled or slotted rotors may outperform an OEM replacement due to better thermal cooling...not sure though.)

I ordered mine from chadrotors@hotmail.com

I got them quick, he answered all my questions, everything went great.

E-mail him with what you have and what you want, and he will get you a price.

Take it or leave it, but my advice still stands. Do not buy x drilled rotors for street cars (forget the likes of Porsche as the holes are put in at the time of casting and use a higher quality material).

Also, thermal cooling is not always better on x drilled either as there is physically less surface area due to the holes.

I do realise that there are many people out there who have x drilled, but at the same time I have seen the results of a vicious heat cycle on these types of rotors and the resulting cracks. And how many people physically inspect their rotors for damage?

Save your dosh and buy OEM rotors and then use the $ saved to buy some decent pads.

your best bet. i love them

[Akimbo]

I can't find Celica ones?

[Jdog1385]

http://www.irotors.com/products/20-3.shtml

they're on the list. its about 230 for front and back.

[juBz86]

ok wat if i only get slotted?? this will lower the life of my pads correct?

[dustin15brown]

I love mine from nopi.com they're the #1 cross drilled and slotted.. Not too expensive either

[GT4WRC]

Yes. You will also need to remove the rotors occasionally to clean out the grooves as they 'fill' up with hardened brake dust, effectively reducing their efficiency. Small flat bladed screwdriver is good for doing that.

[BrianGT4]

are the ones from irotor.com oem's replacement or drilled/grooved?

[K-ESD]

This is quite a interesting topic, from what i read it is true that drilling the rotors can make them suspectible to cracking but i can't seem to find any evidence of x drilled rotors cracking on street cars

[playr158]

well you don't drill your own rotors
you need to buy rotors that were design'd and built with holes in it

like irotors, or number #1

[lazer_mjj]

Black Diamond do a different type of rotor for all gen6, grooved, drilled or both good price too!

[nowitzon]

go with irotors ive had mine for a year and still work like theyre brand new
also get those thermo cooled pads also another awesome mod i can stop on a dime.

[djspike]

would the fronts rotors for the gt work on the st? (on the front ofcourse)

[playr158]

NO

only 7th gen assembly (rotor, caliper) will work on st fronts
GT can only be used to replace the rear on the ST
in a DRUM to DISK swap

What are you talking about? The GT rotor and caliper will work on the ST front brakes. Please stop posting random information if you don't know what you're talking about.

lol, I wouldn't do that with my own rotors
I should have mentioned that i was refering to, for example, a set of oem replacement brembo rotors that were drilled after they were manifacture. Some suppliers buy them and gets them crossed drilled with a CNC machine.
Now knowing that drilling the rotors can make them more suspectible to cracking when they are used excessively (like at a track), is there any evidence of it ever happening on normal street cars that the driver got a little too ruff on the brakes on one occasion?

coomer don't be a douche i know what i'm talking about and if you would read his question he said "ROTORS" from a gt and keep the stock ST calipers as calipers were never mentioned in his question "would the fronts rotors for the gt work on the st?"

evidence-
Wearever YH145009
Front; ST Model

Wearever YH145004
Front; GT Models


thank you i rest my case coomer next time look up part numbers

Gt front rotor is different then ST front rotor
and will not work
unless the caliper is changed too

( GT CALIPER Cardone 171777
Reman.; Loaded; Left; OE Metal Piston
Lifetime Limited Warranty )

(ST CALIPER Cardone 191777
Reman.; Unloaded; Left; OE Metal Piston
Lifetime Limited Warranty)

so "Please stop posting random information if you don't know what you're talking about."

thank you

[Coomer]

Ok Daniel, I'm well aware that the GT rotors alone will not fit on the front of the ST.

However, you mention the following:

only 7th gen assembly (rotor, caliper) will work on st fronts

This is just not true. The Seventh gen. Celica assembly is NOT the only front brake setup that will work on the ST. The sixth gen. Celica GT's assembly will also work.

Furthermore, you mention this:

GT can only be used to replace the rear on the ST

This implies that the GT front setup cannot be used on the front of the ST.

Maybe I should've re-worded what I said to say "Don't post confusing posts that imply incorrect information." The fact is though, that you often post incorrect information, and lots of knowledgable people are very sick of it. And if you continue to insult me on top of posting consistently wrong information, then you'll find yourself warned shortly.

[playr158]

so you can inssult members but we can't do the same?
i see well i'll save pickering for off a decent thread

i do edit may saying as the info is right except a picky word
"only" i retract that word
you "could" put a entire gt front assembly on an st
and you "could" but an entire 7th gen front assembly on an st

answer to question
originally asked which i did answer CORRECTLY
"gt rotors do not fit on a st"
order st rotors for an st and gt rotors for an st

unless you want to get into a "swap'

Playr, I've smacked you down before for your constant posting of misinformation regarding brakes and rotors in general. it's fairly obvious that you have no friggin clue about any of these items. Don't make me drag that thread out of the deep dark depths.

dude thats bs but watever screw this

[FallenHero]

Can you feel the love in here?

[FAQdaWorld]

<3?

[djspike]

so for best braking setup for an st is to replace front assebly with 7th gen (and then later on put aftermarket rotors) and replace the whole break assembly in the rear with gt (6th gen) (and then later on put aftermarket rotors)
i am sorrie i am a noob with brakeing systems

thanx in advance for help

[Silver94CelicaOw...]

I'll try to help you out a little. I got a set of rotors from irotors.com and a set of 4 Hawk performance pads for my GT, and it stops excellent. If I were you, I would go to irotors.com for your same brake needs where you could upgrade your front rotors if you want.

However, I want to advise you that they list the ST as having a front and rear disc brake combo available, which doesn't make sense since the ST uses a rear drum (unless its a upgraded drum setup??) Before you order that package I would call them and talk to a representitave directly so you dont get the wrong product.

What I would tell you to do, is that depending on your needs you should first look into the front rotor setup for the ST, then if you want to go further you can acquire the caliper setup from the rear of a 6th generation GT and use the rear rotors found on irotors along with the ST fronts. Good luck, and if you have any questions just ask.

[Jeremy1210]

From reading previous topics, it doesn't really matter what you want to put on the front. 5th, 6th or 7th gen gt's . The difference in size is minimal and I doubt that you would be doing some serious braking to really need the difference in size, So it comes down to cost. I think you'd be better off buying front gt calipers form a 6th gen.(might be cheaper and easier to find) And Rotors From irotors if you are looking for something nice looking. If not go with stock replacements.

As for rear, I have my rear setups from 5th gen celica. It works fine. I also have irotors on the rear. I like em, and there is a difference in braking from drum to disc.

Go with ceramic pads, I like 'em, but this isn't what I like or what anyone else likes, its what you like.
