drilled and sloted rotors worth it?
 
so i need to do my brakes and money is tight, but i could swing some drilled and slotted rotors, with stock calipers. worth it? if so whats a good brand?

They look nice... I wouldnt get ones that are actually drilled, more often then not they will crack.
they say slotted helps cool them off and clean the pads.
If you can get slotted and dimpled for slightly more i would do it but dont break the bank for them.
you also want to look at coating, are you worried about them getting rusted?

I would only do it if you go to a plus size rotor with a caliper relocation bracket. Should give you a little better stopping. If you're going with stock size I'd just go with OEM...they last forever. 163,000 miles on my truck and I'm still on the original rotors and only my second set of pads.

:stupid: like thunder said get the drilled and slotted rotors but get the plus size ones make a bigger differance then the stock size drilled and slotted
and if thats out of your price range then just get a stock set with a good set of pads.
if you really wanted to you could do these:devil:

Where did you get the relocation bracks for those calipers??

colekill 10-23-2008 11:51 PM

can you use stock calipers with plus size rotors?

yes the kit comes with a new hanger, everything bolts up the same, you need 18" rims or bigger though, depending on the kit

There's a guy over on GMFS who makes them. The problem that I've heard with the Vette brakes is that they use 6 individual brake pads that are very expensive and don't last long in a Vette, much less in a truck that weighs almost twice as much.

Slotted and cross drilled rotors are waaaayyyyy worth the coin!!! It will eliminate the warpage that the OEM rotors are notorious for.

I have a set on my truck that i got off of ebay for like180-200 shipped for all 4. Worth the money. I have cross drilled rotors on my truck.

chevrolet all the way 10-24-2008 07:55 AM

i would do it. expesially if you get em coated so they dont rust too! look better and perform better!

IMO I would only add slotted and drilled rotors if I want to make it look pretty. Years ago, the slotted rotors were used in race applications to handle the gas build up under heavy braking. The materials used in today brake pads has eliminated that problem. If you look at any of the Corvette racing setups, they almost all use smooth surface rotors. Look at the C6R Corvette...flat finish rotors.

+1 its all for the looks.

You can't be questioning the effectiveness of the slotted and drilled rotors are you? Trust me , they do what they were designed for. With "flat" OEM rotors and flat "aftermarket" I am always replacing them for warpage. The slotted/drilled rotors resist warpage very well. Trust me...I work in a Service Dept. for a living.

Gordy M 10-24-2008 04:33 PM

The reason they resist warping better is because after market slotted rotors are generally thicker. I go through 4-5 sets of rotors and pad on my corvette every year because of time trials, hpde, autocross, etc. and I have paid three times as much for hd slotted rotors that last twice as long as the cheapest stock rotors. On my truck, I run the Hawk HD truck pads, dot 4 fluid, bleed the brakes once a year and see very little taper after 60,000 miles and occasionally pulling a 7500 lb trailer.

Gordy are you running stock rotors on the truck?

Here's a link to where I got mine, but I would get the stainless lines too, they did more for my stopping than the rotors did.

Yes with Hawk Super Duty pads

Noah Burns 10-25-2008 06:13 PM

I upgraded my truck with an earl's line kit, new slotted/drilled rotors, rebuilt calipers, and hawk pads, and honestly enough I was pretty let down with the results I got out of it. They work well, just don't feel any better than stock rotors and stock pads. They look great though.

I 100% agree. Im a GM Tech and the stock rotors do nothing but warp. Put stock size slotted SSBC rotors and pads on my 04 Silverado and what an improvment.

not only that, but lets talk brake fade! I'd like to see some people really tromp on a set of flat rotors with 'regular' brake pads, vs slotted or cross-drilled. tell me which one has brakes after abuse still ;)

+1 absolutely!
