Upgrading my rotors

[rudy_kid]

whats better slotted or cross-drilled?

and can i increase the size of my rotors and keep
everything else the same
or what else will i have to change?

what set ups do you guys have for your brakes?

i was looking at some powerdisc rotors

anyone heard of them?

If you have a sedan or SR5 2door, you can get the caliper brackets, calipers and discs from an AE92 GTS 2door, they're bigger. Also, you can get the rear brake stuff from the GTS and do a drum-to-disc swap.

Depending on quality, drilled rotors can crack... slotted are better but don't have as much cooling performance as drilled rotors.

I'd upgrade to either one, bigger rotors would require a bracket upgrade though but either way most rotors i've seen are usually made to fit the stock heatshield and calipers.

okay yeah that makes sense, and seeing as how
im not going to be doing to harsh driving i think slotted will work
and i have a gts so i already have 4 wheel disk brakes


i think i read somewhere that i can fit AE101 calipers
is that true? and would it do it any good?

has anyone upgraded the size of their rotors?
was it worth it? what needed to be changed?

[canadianae92]

drilled is only really any good for wet stopping

I personally like brembo blanks. Not drilled or slotted but good quality long life rotors. Drilled and slotted eat pads far quicker than a stock disc, if ou need more stopping power look into sone real nice pads like hawk, brembo. If it's not a race car drilled slotted are a bit overkill.

Blank rotor has more surface for braking. Now unless you're actually going to go racing, then theres really no use. I've tracked my corolla with the thin non cooled front disks (now I have cooled disks) and suffered no brake fade Just get some bendix metal king plus brakepads and new fluid and you're all set

I do not do any running on track...got Brembo blanks and Hawk pads. Stopping is great...!

^ that's all you need.

most people I know that run on the track regularly don't run slotted or drilled rotors because they don't last long enough under extreme use, even when cryo-treated.

just get a nice set of brake pads and flush your fluid with some nice fluid (at least DOT 4) and you should have all the brake you'll ever need.

remember, brakes can only stop you up until your wheels lock up. If you can lock up your wheels, the biggest brakes in the world won't make you stop any faster.

That's why I'm installing a ABS system on my AE92 aswell
(Got the complete system out of an wrecked AE111)

I upgraded to AE101 calipers and rotors. (238mm diameter for AE92 rotors and 256mm for AE101 rotors)
That means more braking surface and even with OEM toyota pads and rotors it made quite a difference.
That upgrade was a straight bolt on job!

When the project is finished, I'm also going with Brembo blanks, Ferrodo DS2500 pads, steelbraided brakelines and I always use DOT 5.1 brakingfluid.

That should stop me a bit faster

This is only true for the 90-91 GTS, otherwise they are the same size as the SR5 or sedan's.

This what I've done on my sedan. There is a thread on it somewhere, just search "brake upgrade".

Instead of adding ABS... just take the time to learn threshold braking.

Car and Driver (June edition) have an article on brakes that you all might want to read.
They wrecked a Nisan NIZMO 370Z because of brake fade, in the same corner where I experienced brake fade at Virginia International Raceway.

Now I don't feel so bad about my Corolla brakes.

Anyway, their conclusion is that good cooling is the best way to avoid fade, (in addition to good pads and fluid) so I am going to see what I can come up with as far as cooling improvements.

It's a good read. Try and get hold of it.

something else to consider:
(although I know there are other variables)

F1 does not use drilled or slotted.

You are right.
They are carbon fiber, and I think they are multi-plate like aircraft brakes.
They look quite dramatic when thay explode too.
