C7 S6 Brake Performance Rotors - REVIEWS???

[thorlax240]

Hi all!

I have a brake job coming up and I'll likely be getting some ceramic pads but haven't settle don the rotors. People keep recommending brakeperformance.com as a great cheap option but the only feedback I've gotten on them are negative reviews on BBB.org for customer service as well as pretty consistent statements that the rotors warp after about 5,000 miles.

Have any of you had a positive or negative experience with them?

[Audibot]

I've used them previously on my B7 and they were great. Slotted set paired with Hawk HPS pads for 45k miles. They never warped, and had a lot of life left after I took them (I upgraded to a bigger brake, so sold them off). I drive spiritedly too, if that helps.

I currently have them on my C7, at least the fronts (400 mm). Not quite 500 miles on them yet but bed in fine and they feel perfectly smooth and great response currently. Still driving spiritedly too. But this is my first time using their ceramic pads, so I do not have prior experience on this.

Brake Performance also says they have lifetime warranty against warping and cracking.

I have a brake job coming up as well so I am in a similar position.

I looked at brakeperformance rotors but they do not have any specifications on their site for the rotors, specifically the dimensions.

ETA: Can anyone confirm their drilled are 400mm fronts and 356mm rears? I sent them an email to inquire and hopefully they respond but I will call if not.

[Dan GSR]

Wow. Thats a big difference in price. Thx for the link
Rotors this big usually don't warp
More often it is uneven pad deposits that feel like warping

I did some pics and measurements when I received mine. I imagine they just drill the blanks, the latter of which are what I got.

Here is the link of what I got in the kit: https://www.audizine.com/forum/showt...1#post13728534

Or improper install where something (like the caliper) moves.

Bear in mind they are one piece rotors vs. OE aluminum hat set in pins to the iron disc. (S6 fronts)
From audibot:

[LawDawg]

There it is! I was about to ask how in the heck they were so much cheaper than OEM. I get that Audi is very proud of their brake rotors, but sub-$200 for a pair is insanely low.

[Twkdcd595]

So for some reason I was thinking the brakeperformance drilled units was an each price but it is actually for a pair! That is insanely cheap at the current sale price.

I received an email reply...

Yes, these are the correct dimensions. All Brake Performance parts are OE specs and fit.

I got the full set of dimpled/slotted put on about 2 months ago, so about 1200 miles on them so far. I got them with the ceramic pads from Brake Performance. Been solid so far, performance feels like OEM, almost zero squeal (I get a little now in the morning, first couple of stops, but that's it) so for the price I am happy. I do not track the car, so cannot comment how they would perform there, but so far I am happy with them.

[bhamcarnut]

I installed my brakeproformance dimple d/slotted with ceramic pads a couple months ago also. Have about 3,500 miles on them. Absolutely love them! Amazing looks, OEM, if not better, performance and zero squeaking. I used high end brake grease, went with new brake lines, and changed my fluid during the install. It am extremely happy with the results.

Ordered a set of drilled black zinc coated for both front and rear.

Exactly what I did. You will be very pleased!

I agree with everyone here. Their front rotor / pad combo is a steal and no complaints. Wheels clean and slightly worse than OEM braking. Their rear rotor/pad combo is on par with OEM cost though and similar to front cost. Have not had to replace those yet. I don't understand why people pay Adam's rotors when these are available.

See pics of front and rear slotted/dimpled brakeperformance.com rotors on my scale right out of the box.

36lbs for front?! Holy hell those are way heavier than stock OEM.

I guess we now know why they’re so cheap! I’m not looking forward to feeling that weight. What is stock weight?

Stock weight is 33 lbs for front and 19 for rear... based off what I could find searching online. So not that much less than these and the weight savings is in the center hat material so it is only a very margin pick up in rotating mass at best.

I can confirm that weight soon when I weigh my used ones coming off my car in favor of the below going on the car. I should weigh the below as well to see how they compare being only the drilled versions.

Now if only the pads I ordered (z26 ceramics all the way around) were not on backorder for like 30 days.

[coop3422]

Following this thread for sure. Picked up my 15 A6 at the end of April, and it supposidly had new brakes all around. In the past 2 months I've noticed what is likely front warped rotors, which apparently is common on the A6. Since pads should be new (will have this checked), I'll need new rotors and want a good solution that won't warp.

Good point about rotational mass. I felt that all too much when I went to 21” wheels but of course that weight was 10”+ from the center hat. Will report back.

Does 3 extra pounds per side really make that much of a difference?

Where did you buy those rotors? I went to rotorperformance.com and didn’t see that drill pattern.

BrakePerformance.com, they have a number of options in rotor styles depending on your preference/ application.

Yawn.... it’s a heavy Audi s6 v8.... a few pounds on the rotor won’t
make a difference.

I’ll be swapping out my brake performance rotors for the girodiscs. They weigh 22lbs.

Not bad. If you wear em out. Can replace just the friction surface

Exactly! I’m just waiting to hear back if they make a rear set. Seems to be missing from the website.

Oem rears are 1 piece

Stage 3 power has left me longing for more braking. I’ll be interested to see what you think and what pads you choose.

22 lbs? Their site says stock is 27.4 lbs, but stock is 33 lbs. So are they really still 22 or are they more like 28?
I’m just not sure how they’d shave 11 lbs, 4-5 I’d think is possible, unless the plates are much thinner than stock, but that doesn’t make sense.

A few pounds in the most sensitive part of a car do make a difference...

Understood, but if you are going to upgrade brakes, rotors are in the equation.

[Twkdcd595]

If they did reduce weight that much I would be concerned about what point warping potentially becomes more of a concern. You can only take so much weight out of the hat area before you have to start removing material in the outer areas as well. With less material you can certainly heat soak a rotor much more quickly and cause it to warp, especially considering these cars weight.

I had GiroDisc front rotors on my old B8 S4 for several year & had no issues with them. They are pricey, but are lightweight, due to the aluminum hat.

"The central hat section of our rotor is made from strictly U.S. sourced 6061-T6 aircraft specification aluminum. The disc is made from our own proprietary cast iron, poured in the USA and machined from start to finish in house at Girodisc. The rotor utilizes a curved vane design, developed in racing to act as a centrifugal pump to force cooling air through the disc.

The rotor and hat have a floating mount system, which utilizes 8 or 10 high strength alloy steel drive pins, manufactured by Girodisc in the USA to our own specifications and cadmium plated for a long lasting corrosion resistance. These pins take the load from braking actions while maintaining the axial and radial float between the hat and disc. The pins are secured by grade 12 cap screws with hardened washers. In order to keep the rotors from making noise when cold, the pins are mounted with anti-noise spring washers on the rotor side which allow the rotor to grow with heat expansion but eliminate the rattle and noise associated with floating rotors. This float also allows the rotor to self center between the pads."

[Twkdcd595]

Interesting, I personally cannot justify the extra $1000+ for the fronts alone but its good to see more rotor options for people who want to take a more max effort approach with lightened rotors.

I have to say I would be curious to see one of these 400mm lightened replacements scaled, that seems like a lot more weight than I would expect in just the hat material.

[Nick Fury]

I'm on my 3rd Audi and 3rd set of BrakePerformance brakes. Upgraded my fronts from 356mm to 380mm dimpled/slotter and really like them. Can't beat the price & lifetime warranty.

[thorlax240]

UPDATE: Installed dimpled and slotted setup with Brake Performance ceramic pads front/Akebonos Euro Ultra Premium Ceramic rear on Friday without issue. After bedding and a couple hundred miles this weekend I can say I'm happy with them. There's definitely a SLIGHTLY softer pedal feel but nothing to complain about with the lack of brake dust or squeal anymore. Additional rotor weight doesn't affect butt dyno at all IMO. Would recommend for this price.

[jbs6]

Thank you all for sharing your experience with Brake Performance. I’m on the same boat, doing a brake job and will purchase Brake Performance dimple and slotted with ceramic pads. They have a sale now, giving the hardware kit for free when purchasing their brake kit. Will share experience when installed and driven
