What type of New Rotors should I buy??

[slidr]

I've been doing some searching on this site and others for the answers, but have not come up with a conclusive answer.

I have nearly 100k with the stock rotors on my car and they are fairly warped, and instead of getting them resurfaced or getting new stock rotors, I though I would try and upgrade?

So what type of rotors would be best for my GTS? Not only for daily driving, but also for autox events which I will be entering next year.

Should I get slotted rotors, slotted/drilled rotors, dual ventilated rotors, cross drilled, etc?

What's the difference between drilled and cross-drilled?

Will drilled and slotted rotors eat brake pads faster than stock rotors?

Should I use Toyota OEM pads (new, which I already bought a while ago) or are they metallic and will they eat away at the rotor quicker?


Any suggestions would be appreciated.

I'd go with just slotted, since cross drilled could potentially crack under extreme braking (though you shouldn't seem much of that in autox), and some tracks won't let you on teh course with them because of this reason. Drilled and cross drilled are the same thing. I would assume slotted would eat away at the pad faster due to the sharp surface, but they should also help keep the surface of the pad smooth if it ever starts to glaze over. OEM pads (semi metallic, I believe) seem to be very rotor friendly and will last forever, but there are better pads out there. Which pad you want really all depends on how much dust you can stand. The better the pad, usually the more dust it will create. I have Axxis Ultimates (kevlar ceramic), and they're incredibly dusty, but they feel and perform insanely well. I'm gonna try out some Porterfield R4-S (carbon ceramic) very soon (just placed my order today), and hopefully they'll have less dust at a similar performance level.

I have Rotora slotted rotors with axxis pads no complaints yet.

I've been more than content with my Stoptech slotted rotors...

Thanks a lot guys.

It seems that slotted rotors would be best for me.


Just one question though...

They don't make slotted dual ventilated rotors, do they? I'd assume that they only make slotted and/or drilled dual ventilated rotors because if they aren't drilled, then having the empty area between the rotors would be pointless since no gas would escape to there.

But if the dual ventilated rotors were just slotted and not drilled, then perhaps the empty area on the inside of the rotor would cool the brakes faster?


Are the stock rotors dual ventilated? There is an area in between both sides of the rotor, but it isn't a truly open area as seen in the picture below (far right). The stock rotors seem to have little "teeth" like divisions bridging the gap. But come to think of it, I've never seen a dual ventilated one like in the pic below without those teeth or divisions.

Are you going to be using them with your cross drilled and slotted rotors?

Are you satisfied with your current rotors?

The fronts are vented, but the rears are solid. I'm gonna try out some Porterfield R4-S (carbon ceramic) very soon (just placed my order today), and hopefully they'll have less dust at a similar performance level.

Yes and yes. :) Zero fade, great feel, just a bit noisy when I step on the brake at certain pressures since the slots and holes make noise.

Should the aftermarket rear rotors be solid also, or can I buy vented?

Or would it not even matter since the front brakes do most of the work?

[Blue Bomber]

The rear rotors are very thin compared to the fronts (like 1/3 as thin). If you used ones as thick as the front, the rear calipers wouldn't fit over them.

I am using Brembro slotted rotors and have no complaints whatsoever. IMO it is one of the best investments I have made.

[ibanezgfx]

I i think i might get some slotted rotors and new pads considering i reallllly need brake work done to my car.
i have to pump them before they grip. i thought they needed bled, but 2 mechanics said otherwise.

[SharkyGTS]

Anybody tried SP Performance rotors? They have slotted, drilled, diamond slotted, and slotted&drilled. Supposedly they drill their holes so it has a smooth radius to eliminate hotspots and breaking. I dunno. I found a place where I can get all 4 for 330 ish. Just thought I'd ask.

yeah i have rotoras too..they are pretty good
next time im gonna go with stock or trd pads though cuz green stuff seem to squeak a lot and makes tons of dust

[demongt]

get a big brake kit
