I will need to buy new rotors soon and I want to know what would be better to buy. Powerslot has the slotted rotor that I kinda like but brembo has the vented and is much cheaper. Is slotted rotors going to help the braking process better? My mind is made up on the brake pads AEM high performance pads from OSS. I just need to figure out what rotors to buy. I want something that will have better braking than stock but not cost too much.
rotors nowdays are all vented. Those brembos u r talking about must be just the blank ones. You can get drilled/slotted/dimpled brembos for $99 a pair (if that price still holds). Check it out in the suspension forum. Slotted rotors will help
your choices are really drilled, dimpled, or slotted Brembos, or Powerstops (drilled) or Powerslots (slotted). your only real question is which is better, drilled or slotted, and personally i thinik whichever you can find cheaper will be fine. on nopi they are pretty expensive. we sell Powerstops and Powerslots at work for i believe about $65 each so they would probably be cheaper. Powerstop is made by Universal Brake Products so most regular parts shops should be able to get them.
I just got the powerslot slotted rotrs two weeks ago, and to my surprise they are actually made by Brembo, for the Brembo name with logo is etched into the top of each rotor, weird huh...
Anyway I picked up mine for $140 for the pair, at a local performance shop, and they seem to be working fine, except they have acoating on them which has to be burned off through the 200 to 500 mile break in, so once all that is gone, they will be workin good, but until its all burnt off they pads are pushing on the solution rather then the metal of the rotor, so thats just the way they are, so... there still amazing rotors, they just have a break in period which requires you to go eacy on them until they ae down to the metal...
Definately get slotted vs. cross drilled, cross drilled has a history of cracking, and that can be backed by almost every magazine, and dealer around, in fact I wanted cross drilled for the looks vs. the slotted, but the guy at the shop said he wouldn't offer them to me because they crack (and he wasn't just sayin that to make a buck, he's an amazing guy and does awesome work, I've actually had him and his staff do almost all the work on my car, and I've seen other cars they've done, and they have come out with some awesome stuff)...
where do i get brembo rotors?
i would get the slotted rotors over drilled anytime.
drilled rotors have tendency to crack if they don't get break in just right or they can be made wrong and that can cause the crack too.
when it comes to slotted. they help to relieve the gas that gets created between the pad and rotor.
slotted are good but I don't think its necessary for these rotors unless you really used your car. If you are autocrossing I would reccomend these. Even with autocross, stock rotors with better brake fluid and brake pads will improve braking dramatically.
Good street/spirit driving setup:
Brembo Blanks (OEM style rotors)
AEM brake pads
Stainless Steel Lines
Dot 3/4 Brake fluid
if possible, Rear disc conversion included in that.
Although I have a question myself. Do the AEM brake pads wear out the rotors faster than OEM pads? I am in it for durability/braking performance and I must figure out the pro and cons of each brake pad. I will need to get some new ones soon. :D
I've had the powerslot rotors for over 2 years and they still work like new. You might look into running a dot 4 or 5 fluid as well. I use a non-synthetic dot 5.1. It's actually cheap and can be mixed with dot 3 or 4 so you don't have to flush your brake system like you would with synthetics.
don't some of the new mercedes come with drilled rotors? oh and porsche?
I would just get the brembo's as i have seen them up close and look nice. I have had both powerslot and cross drilled ones and they both sucked. They warped very fast under normal driving so i gave up and went back to stock on that car. But 88Lxi68 has them on his coupe in the front and rear and they are nice and i have not heard any complaints from him.
slotted is good for GRIP,the slots grab onto the pad under hard braking for better stopping power,crossdrilled are ver ygood to,dont let stories of cracking fool you-I did belive that at one time too-with drilled it lets the air that gets between the rotor and pad escape-under hard braking a normal non-drilled rotor actually pushes the pad away from the rotor surface because of the pressure-as where the drilled let it escape throught the veins-brembo and powerstop are both very good-I have seen both last a longgg time-I hope this clears up things alittle
I just finished my full brake upgrade a couple weeks ago, and already had one get-go at an autox event, and it was great! The brakes are very firm, very silent, and look great. There isnt much more I could ask for from it all. I did the following things:
Powerslot Front Rotors
EBC Green Pads
Brembo Drums (clear-coated so wont rust)
PowerStop Rear Shoes
New Rear Wheel Cylinders
Flushed Entire System
My initial decision was torn between wanting the EBC Slotted/Dimpled rotors or the Powerslot. I like to stick with one brand if possible, and I always figure their items work best with other matching items they produce (after all, they wouldnt factory test using a competitors item). The EBC rotors are dimpled though, which is to eliminate the cracking you get with a full cross-drilling. But just like EBC says, the dimpling is for the LOOK of a cross-drilled rotor, that "high-performance" look. It serves no other purpose than that. And when more miles are racked onto the car, more brake dust gets in the dimples, making them black and looking just like cross-drills.
So you're getting the look of cross-drilled rotors, and no other function. But it is taking away the surface area of the brake rotor. So in reality, you will likely brake slower if you were still using the old pads, but it would look 'cooler.' It's your decision. Possibly the most important factor in better braking besides the caliper, is the amount of surface area that the pads are allowed to use to stop the car. You dont see Formula cars with cross-drilled rotors, yet they are using massively huge blanks. There's a reason. More surface-area = more area the pads can grip to slow the car.
The only true need for slots or cross-drilled applications are on high-speed cars. Not only do you not see enough glazing or fade (with a good pad) on the street, or even autox'ing, but you are also decreasing the heat dissipation of the rotors. More material dissipates the heat better, that is why race cars run super fat rotors. The main purpose of cross-drills or slots nowadays, since very little 'gas' comes out of pads anymore (unless you run 1970's pads) is for the dust that will form, and for water. Otherwise, stick with blanks, or even slots if you do enough racing to possibly warrant it.
All I have left to say is make sure you do the break-in! And just because they say a few hundred miles doesnt mean you can go on the highway. Think about it, you arent using the brakes going 70mph for a couple hundred miles. You have to do city-driving. I couldnt be happier with my brake decision, I just wish I had rear disc now!
f1 cars also use carbon composite rotors haha
Brembo blanks already have a very high Carbon content. That's why most other companies use Brembo blanks as their base to improve on.
I’ve got the Brembo cross-drilled rotors at all four corners, along with Axxis pads. This combined with the techna-fit SS lines, and a dot 4 synthetic fluid makes for a pretty damn good setup. I have 88-89 LX-i brakes up front, and the SE-I disc out back. I have to say that as for pad/rotor wear, this combo is great. The rotors have held up better then I could have ever wanted, and the pads still look near new despite the 15K + I have on them. The differences between this setup and a stock setup are only apparent during heavy braking, or with moderate-heavy continuous braking. Remember though that this setup was chosen for auto-x, and not daily driving. For daily driving, I would suggest, as most others have already, just a Brembo blank with the AEM pads, or as I have, the Axxis pads.
The reason I like the Axxis pads is b/c, unlike the conventional pad, or even many aftermarket, these tend to grip harder as they heat up. Just the opposite is normal, typically after a pad heats up, you get “brake fade”. Here, the hotter they get, the better they seem to grab. But the downside to the pads is the excessive amount of dust they create, and that as they get hotter, they obviously tax the rotor more.
Just a quick note about the cross-drilled rotors… I did notice recently, now that I have the hatch back on the road, that the rotors (and I’m guessing it’s due to the fact that they’re drilled) make a very distinct noise while braking. You can litterally hear the air being dissipated through the drillings. Very cool sound.
Just my .02
Talk about revamping an old thread :)
I went with EBC Sport Rotors and EBC Greenstuff brake pads for the front brakes.
I've got the Powerstop crossdrilled rotors, which are Brembos, but Powerstop does the drilling, and haven't had any problems. I'm using Axxis Metal Master pads, and this set-up has been great. Over a year of use and still counting. The drilled rotor are meant to displace heat and dust better. I'm also using Powerstop brake shoes(relined ones, but uses ceramic material) with Brembo Drums. Makes a good combo for an 87 lx-i, I think. I do need to find some SS brake lines though. Anyone know where I can get them?

Not to say you made a bad move but I"ve had a handful of customers come to me after getting a set up w/ your front combination and after a good 8 months to a yr their rotors warp. I didn't do their install, but power slot will even back up the fact that the ebc' gr's aren't a good match for powerslot rotors. They start to leave a black residue over a period of time. Head's up in the future. Powerslot gives a recommended pad on the box of the rotor, and it does work.
Do we get to hear what it is?Quote:

I need to get some Red's before the next event.
