Lighter than OEM brake rotors??

Is there any other options besides Racing Brake to find a lighter brake rotor.
I looked at R1comcepts and they are basically the same or at most 1 lb less than factory?

Racing brake saves about 5.5lbs per front, and 6lbs per rear.

RB is the only one worth doing. If a one piece claims to be lighter where do you think the material came from? The wear surface. So you just bought a cheaper rotor that will warp or wear out faster.

I know Wilwood makes rotors that are decently light - I could have sworn a member had them on his car, but will have to look for it.

Then I think Granatelli makes rotors - but I personally wouldn't buy anything from them. Well anything that you need to rely on anyway.

RacingBrake is the only one I found with a properly built rotor. DBA are heavier Ganetelli are heavier.

To be honest there is probably other brands out there....but I found racingbrake met the guy who holds the patents and designed them and never looked back

To get much lighter than stock you have to go to a two piece rotor like the RacingBrake rotors. The weight reduction is just one of several advantages that the RacingBrake rotors have over others though.

I purchased the Granateeli rotors this morning and I am driving there to pick them up. I have not looked up the stock weights but Granateli told me the fronts weigh 24.5 and the rears are 23.9. I asked why their brakes were better than stock and they said, well they are stock, Stock Brembo cores that are machined with slots and holes or dimples. The benefit stems from the slots and dimples

Anyway I paid $425.00 and could not pass up the deal. I will weigh them myself before i install them to confirm. Wilwoods were quoted to me at $4557 front and rear in Red or Black

Tried to PM you but it would not work. Are you another victum of GMS or just following that other thread. I tend to want to hear from the real customers not the hear-say

Well I just read this and it makes a lot of sence if you save 23lbs all around but it was hard to beat the $420 price for all 4. Plus on the surface their website does not really make it easy to see the 2010-2013 stuff for the camaro. Love the 23 save though - thats huge

So you paid $425 for used OEM rotors that Granatelli resurfaced, drilled, and slotted? If you're happy about that that's all that matters. Personally I wouldn't trust a rotor that was drilled after-the-fact, way too big of a chance of it cracking because of it. That and the fact that they are used rotors is a little iffy already - I mean who knows how much life is left on them, they've already been resurfaced once. Can't imagine getting much life out of them to be honest.



Wilwoods were quoted to me at $4557 front and rear in Red or Black
If they gave you color options then that quote includes Wilwoods 6 piston calipers, so it's not just the rotors.


Tried to PM you but it would not work. Are you another victum of GMS or just following that other thread. I tend to want to hear from the real customers not the hear-say
I have space in my Inbox, so don't know why it wouldn't let you PM me - but I bought Granatelli's wires on the claim (and supposed proof) that they increased hp - funny how convincing a few dyno graphs can be. They were absolutely complete junk - barely lasted 3 months before falling apart on me. I didn't bother to try and get a refund, just cut my losses.

I'm not sure where you got the idea that they are used/resurfaced rotors. Can you please let me know where you found this information? Also they are not drilled, they are dimpled which has much less of a chance of cracking than drilled rotors.

Best regards,

I was told they were brand new Brembo blanks not used returns - perhaps I misspoke if I lead anyone to understand otherwise - Again I am going there shortly and will confirm. They said they offered them Drilled, Slotted, Dimpled or any combination otherwise. I asked about cracking and they said LIFETIME warranty against cracking and warping. What more can I say - I will let you all know

$4557 was the whole package - here is there link http://granatellimotorsports.com/pro...d-1435-42.html

One place I wrote $425 and then I wrote 4420 - it was $425.00

Speaking of GMS Brake Rotors, this is straight from Racing Brakes website.

Remarks:

Rotors with drilled holes should only be used for street driving, as these rotors may tend to crack under repeated hard braking or in track racing. When choosing a drilled rotor, be sure that you do NOT choose a rotor that was drilled from an aftermarket blank (like many rotors on the market), as these rotors will not be balanced. All RacingBrake rotors are dynamically balanced as their last step, after slotting and/or drilling to ensure even distribution of mass.

One place I wrote $425 and then I wrote 4420 - it was $425.00
The MSRP for each OEM front rotor is $132, and each rear is $174 (LINK to GM Parts House)
So, saying Granatelli paid the "Online Price," that's $397.20 - NOT including the shipping cost to get them to their shop. Considering it cost me $60 to get my Racing Brake rotors shipped to me, and OEM rotors are heavier, they probably spent at least $460 getting these "new" rotors to their shop.

They then are going to drill/slot them, give them a life time warranty, and take off $40 from what they're charging you.


In all seriousness - you really think they're "new" rotors?

No - it's a long story, I explain it in my build thread.

Once you see and hold an RB rotor in your hand, you'll want them on all 4 corners. This is your life we're talking about; and possibly the lives of your passengers and maybe someone else in front of you. If the investment in RB rotors means you can stop 8 feet sooner than you otherwise would have, and that 8 feet means you DON'T hit something in front of you; add up the savings in repairs including air bags and they just easily paid for themselves.

Don't go cheap on something that's absolutely critical to your everyday safety on the road. I've got a full set with their ET500 street/performance pads and combined with stainless steel brake lines, these things will STOP YOU RIGHT NOW when you hit the brakes. They're a very worthy investment; well worth the money.

I just replaced my 2nd pair of oem front rotors due to warping & bought EBC 3GD Black Sport Brake #GD7520 for less then $300 a pair weighting 54lbs.. (http://ebcbrakes.com/product/3gd-sport-rotors/)I will let you guys know what they are worth on the track in a couple of weeks..

So that's about 27 pounds each - making them heavier than OEM.

Good points Doc! How long would you expect these to last under daily driving and occasional drag strip passes?

You'd probably go through two sets of brake pads before you'd need to replace them if that's all you use them for.

Yeah at least, and then you might need to replace the fronts. Unless you're road course driving these will probably last for years and years before you'd need to replace the front rotors. The backs will last even longer since they don't handle the load like the fronts do.

Cool! Thanks guys!
Doc, did you ever take your car to the drag strip just to see what it would run?

No but based on the power and weight it would probably run somewhere in the mid 11's.
