Who has the kit on here? I was checking out RRE's website and the AEM big brake kit, and it looks like the pads that it takes are the stock size pads? Is this right? What can be the bennefit of a larger rotor without larger pad surface area? Is the kit really worth the money? I am deciding between the kit and the Powerslot rotors...TIA

I believe the big brake kit comes with larger rotors and a caliper relocation spacer. Larger rotors will give you a longer moment arm from your pads to the center of rotation which gives you greater stopping power. Larger pads would arguably help as well, but contact area has never really been proven to affect friction. Friction force is determined by the normal force (piston) and the coefficient of friction (metal rotors to whatever type of pads you use).

anyways, enough theory. I think you can see the big brakes will help you stop faster even with the same pads.

yes.

Yes. Main benefit of larger pads is that they manage heat better, AFAIK.

I have the AEM FWD kit, front and rear. The biggest gain is the better braking modulation ability. It is much easier to hold things at impending lockup, and thus minimizing stopping distance.

For track purposes, the extra mass of the larger rotors will also delay the onset of brake fade. The cost of course is an increase in unsprung weight.

umm, i like them

>I have the AEM FWD kit, front and rear.

What do u mean, u have the FWD kit on both the front and the rear. The front and rear brakes are totally different, so how can
you install the front kit on the rear. I'm curious cuz i wanna do a rear conversion, and that would be great.

Also, can this kit fit into 16" wheels? the Powerstop brakes i have now look like there pushing the limits of my wheels, and they are
stock sizes.

the thing that I always wonder about is.. if One of the Rotor gets Warped then what? get the whole kit again? or a saperate rotor is available? if so.. how much would that go for?

:)

I think Juan meant he has the FWD kit (different that the AWD gsx kit). The FWD rotors are smaller. But they are different for the front and rear rotors (both are part of the kit for the FWD though). Also, if you get the kit from www.roadraceengineering.com, I heard most of the time they can get the rotor warrantied for you if you have any problems. You might wanna ask if u order it.

Marcus got my back... ;)

I have 11.75" FWD kit on the fronts (not the 12.5" AWD kit), and the standard 11.5" rear kit. See here for more info:

yeah I'm waiting on Juan to part out his car....so that I can have the brakes....:P just messing wiht you Juan.

how was your trip?

not so fast there fella, I plan on keeping the car for a while still...

Trip was great. Too short though. I have decided that I want to be on vacation all the time, and not have to work again. Better start buying lotto tickets... ;)

juan

hahahah sound good. Got some interesting pictures with European Chicks?

Go easy on my rotors will ya...:P

hehe.

Hard to get good pics with your girlfriend right there...

Besides, the weather was a little cool, so there wasn't much on display.

juan

tell me you didn't. you brought your girl with you on vacation....

thats why it is call vacation....to get away from everything and everybody :P

glad you had a good time.

Even if it's the same size pad yes it will increase stopping power. The physics of it, say that if you try to stop the rotating mass farther out it will be easier than trying to stop towards the center.

In case you don't belive me go to the play ground. and spin the mary-go-round. And try to stop it at the railing on theoutside edge. Then do it by trying to grab in farther towards the middle, andtell me which is easier. yes i know reachign the middle isharder, but bear with me, I tried to think of an example that would make sense... and it's late.

Una salus victus.

I have them and I feel a BIG increase in stopping power. I don't have to push the pedal as hard to slow down. They look so awesome too. They fill out just about all the space inside my wheels. I lust need to get my calipers painted.

if you want you can get the AEM kit with the DSM dual piston calipers it'll be a bigger pad and you'll have 2 pistons.
