Need to replace brembo BBK rotors

[infam0us719]

So my front and back on my Dinan/brembo bbk have warped and I need to replace my rotors.
Size on front is 380x34mm and rear is 380x28mm.

I've been reading it's possible to run the stoptech rotors, will it work for this setup? What pads would I have to go with?

Does anyone know the best spot to get brembo rotors/pads for the best price currently?

Any advice would be greatly appreciated.

If the rotors are still good thickness wise you should just use a track pad cold and scrape off the pad deposits. Rotors rarely warp. You are feeling pad deposits

I'd give Dave Zeckhausen of Zeckhausen Racing (www.zeckhausen.com) a call to see what he knows about rotor backward-compatibility. He stocks those parts too.

I agree with the above that it's unlikely you warped the rotors. Try to re-bed the brakes.

Rotors are definitely warped. But thank you I'll message him

Did you measure the run-out? If so, how much was it?

He is a busy guy so you may need to leave a voicemail. If it's not urgent, just email him.

You can see it in the pic. Right around the hat. Tire also has a bubble waiting to receive to rotors to put my new tires on

I can't see anything, the photo is too small. You're saying the warping is so bad that you can see it? If so, that's crazy, and I'd want to find out why it happened.

Bump. Any brembo connects ?

Thanks for referring Zach. Very insightful and helped out. Unfortunately he only stocks stoptech

Due to the carbon content of most rotor iron, the rotor will crack before it warps enough to see when tucked behind a wheel. You *might* be able to see an extremely warped rotor if you took the wheel off and inspected it closely, but even then it'd be tough. Rotor warp-age is a matter of a few hundredths of an inch (~0.025" would be pretty extreme run-out), and even then it is rarely caused by overheating, especially on 2-piece rotors. Excessive run-out is typically a manufacturing issue. I would suggest having the run-out and thickness checked before investing in new rotors. As others have said, you may just have pad deposits.

Too bad. What did he say about your warping?

Did you get the run-out measured? If so, what was it? Have you spoken to Brembo about it?

These are the rotors. U can see the warping around the hat

[infam0us719]

Pic didn't attach. There is a noticeable indent. Not coming out great in the pics

[DR-JEKL]

warping is where the rotor runs out of section (this can be checked with say a dial indicator by removing the wheel and placing it on the rotor) and is not necessarly be seen in a pic, only when the rotor is spinning

I think you're referring to the lip around the rotor hat? What this is, is the section of the rotor that isnt wept by the brake pad, so the rotor remains the same section as a new rotor. Get a shop to check rotor thickness with a set of micrometers but yours look fine to me TBH

[M3SQRD]

Agree with the above post. Your pad radial depth is less than your rotor ring radial depth which results in a small area of the rotor ring not being used.

Sadly nothing seems wrong with rotor but the fact they are near due for replacement. Two piece rotor hardy wrap. I cooked mine to 1600 degree F at track no wrapping. But should replace since it's due

[infam0us719]

Yep sorry used incorrect phrasing. Any hookups ?

This is 100% the case IMO. 2 piece rotors don't warp. You're more likely to heat crack a rotor than warp one. I've seen 100 or so people claim their stock m3 rotors are warped and need replacing. I remove them an using 120 grit paper, and a block, light pressure and some careful patience, I remove the thin layer of pad material from the rotor face on both sides. I also scuff the pad surface and make sure they are worn evenly. If all checks out, reassemble and re-bed the pads. In every case the vibrations went away.

Pad deposits can get so bad, that they can easily measure in the 0.002"- 0.009" range and easily make a brake vibration pretty severe.

The largest runout I've measured to date was 0.014", at which the customer opted to replace the rotors with a Stop Tech BBK.

This proves nothing. Get the wheel off and measure some runout with a dial indicator gauge. You cannot see a warp with your naked eye. What you see in that pic is rotor wear. Nothing else.


If you're hell bent on replacing the rotor rings, contact dinan directly. they sell the replacement rings.

Take a look at my rotors guys.

The whole point of this post was to see if anyone had a plug for a discount on brembo rotors. Dinan isn't exactly a plug. Thanks tho

Cool bro. Good luck finding them outside of the manufacturer, or dinan, and they would have to order them from brembo for you. I asked.
