Gallardo / Audi Brake Rotor Options.

[s8prtotype]

Well, since I'm in the market for new brakes, I've been searching like EVERY THREAD for any mods or what else I can use up front haha.

The lambo guys use our stock rotors because they're cheaper, but also searching that forum leads to the v10 R8 rotors fitting the lambo as well, and the newer RS5 rotors are the same as the R8....

I guess my question is will they all bolt up without issue (are the rotor hats the same offset) and does anyone here have an RS5 rotor they can measure to check for sure? I have a lead on some for a decent price...

Like these...

I know ;) This post is for every other option out there that may work.

Just so everyone is aware, Advance Auto has the stock like Zimmermann rotors on their website.

What that means is that you can add just one side to the cart, and put in discount code TRT30 and you've just saved $50 bucks. Making the rotor $266.38 Shipped. Cheapest I've seen so far. Then just do it again for the other side. And maybe some hawk pads ;)

Stock up! :)

Anyone have the part number for the back?

[s8prtotype]

I have confirmed the RS5/R8 wave rotors do actually fit perfectly on my car. So that means any of the big brake kits offered for those cars will fit on our C5 RS6

Don't mind the dirty floor it's just some random garage with a lift i have access too :)

Now rocking EBC Yellows on the ride.

[4everRS]

Great find!

Edit: is there a year range of rs5/r8 that we would search for when shopping? I'd like a"floating" option like our stock ones, but but slotted instead of drilled.

[s8prtotype]

If you just want slotted only I'd just go with the Girodisk rotors (cost wise)... which I plan on doing after I have 19's on. Brembo makes a slotted only 380mm rotor as well.. but it's $$$$

http://www.girodisc.com/Girodisc-Front-380mm-2pc-Rotor-Upgrade-for-Audi-RS6_p_6543.html

If you don't want to upgrade the wheels the ECS tuning RS5 rotors are now an option... Maybe they'll make just slotted for stock sizing as well??

http://www.ecstuning.com/Audi-B8_RS5--4.2L/Braking/Rotors/ES2603007/

We share the same Rotor offsets as the 2013-2014 RS5, The gallardo's and the R8's.

[mik15]

has anyone tried the ECS ones? they seem very appealing and good looking rotors :)

[s8prtotype]

I don't think anyone has considering I just figured out the RS5 rotors work. :)

Give them a shot and let us know! I haven't seen any reviews on them for street use yet, but i did find a bimmer thread on them with some info...

What model year Gallardo & R8 OEM Brake Rotors (http://www.ebay.com/itm/NEW-Audi-R8-Lamborghini-Gallardo-OEM-Front-Disc-Brake-Rotors-420615301D-/271636274137?pt=Motors_Car_Truck_Parts_Accessories&hash=item3f3ec89bd9&vxp=mtr)are a direct fit for the RS6? Do front and rears both fit?

[marklar182]

only fronts of the Gallardo/R8 rotors fit. All years.

only fronts of the "Wave" rotors fit as well, rears are smaller than our stock rears.

[s8prtotype]

The newer RS4 Avant and the RS5 have bigger wave rotors for the rear and all you have to do is space the caliper to fit. :) But you need 19's at least.

There is also a bigger factory front rotor and you'll need 12mm-15mm caliper bolt spacers, but I've found it's much more cheaper to use the Girodisk rotors cost wise, and they're probably stronger for track use.

What size are the rear brake discs you're talking about, because I find these Audi RS5 2013-2014 on ebay and 330mm brake discs are smaller than the RS6 C5 ?

[s8prtotype]

Actually you're correct, (my mistake) the rear seems to just be a match to the wavy style fronts, but the offset of the rotor hat needs the caliper spaced a few mm (around 3mm) to work I think, not sure yet I haven't done the rears, but was talking to someone who has via email.

[Bigglezworth]

Larger dia clearly designed for a larger brake pad. You're photo shows 25% of the rotor not being used. Defeats the purpose of having larger dia rotors IMO.

[Bigglezworth]

On another note, here's a PM blog about Audi's 'wave' rotors...

http://www.popularmechanics.com/cars/news/auto-blog/automotive-brakes-get-wavy

[s8prtotype]

Yea i noticed that, Looks like you could just use the RS5 brake pads? Not sure if they would extend through our caliper as well.. but maybe you need the RS5 calipers for the full effect.

This is why i'll probably just do the 380mm Girodisk rotors in the future as it will always be cheaper to replace the rings after the first set.

[Korben007]

What is the advantage of the wave rotor anyhow?

[marklar182]

What is the advantage of the wave rotor anyhow?

Less rotating mass

[lswing]

What is the advantage of the wave rotor anyhow?

Heat dissipation of the rotor. The wave creates more surface area than just a standard curve. More surface area to air, allowing more heat to leave the rotor. Read this on one the manufacturer pages, seems to make sense.

[G2]

Far as I can tell ONLY the C5-RS6 uses directional rotors for Left and Right sides. Spent plenty of time working on a R8 lately and I know for sure the rotors run backwards on the right side. Unfortunate to see this. But obviously huge cost savings for VAG...

Probably makes little to no difference unless someone tracks the car-- definitely on the R8. It's brakes are awesome; so NOT nose heavy like our 6's- the rear pulls down and feels planted like a 911 under hard braking (love it). Would say the RS6 is possibly the exception with "needing" directional rotors, due to experience with warped rotors (on 2 cars) that are street driven. Will be checking out a 3rd RS6 next week, original owner, always dealer serviced-- see how that one fares on it's first test drive.

For cheap would stick with Zimmerman rotors to keep the function. Obviously the newer style rotors may appeal visually to some. I can get any of the those rotors for fitment checking, but would need some committed orders to justify the time. Cost competitive compared to on-line seller and with warranty (sounds like some places do not accept returns or do warranties).

I currently have a new set of RS6 OEM front rotors sitting in my office.

[G2]

Heat dissipation of the rotor. The wave creates more surface area than just a standard curve. More surface area to air, allowing more heat to leave the rotor. Read this on one the manufacturer pages, seems to make sense.

Due to the rotor thickness, any gains in heat dissipation in the wavy design can't be much. But maybe enough to offset the rotor vane design? Only those running the brake dyno's know the truth....

On the flip side some thermal mass is lost, but it's a cleaver way to keep weight down -- possibly cost too -- while potentially making a bigger rotor to increase the mechanical advantage. I think it's a collaboration between marketing and engineering to make the cars stand down more. And the bean counters. That's the tug-o-war that always took place when I was in engineering.

[s8prtotype]

Ok, Since I already figured out the front.... it's now someone elses turn to figure out the rear...

Turns out the new RS7 has wavy 14" rear rotors, and boy does that offset look so close! You would just need (I hope) a caliper spacer to move it up like the fronts. OR maybe the RS7 caliper will work.

SOMEONE MAKE THEM WORK lol

So, I'll throw another one in the mix. For the RS5 so it should fit ours right?

As long as that lower bracket mounting point is the same as ours then yes, it will bolt right up.

Pretty good price for this whole kit.

http://www.ecstuning.com/News/Audi_B8_RS5_ECS_Stage2_FrontBBK_2013_2014/ES2793048/

I'd ask what the rotors and brackets/bolts cost only... Don't need all that other stuff unless you need pads and lines.

The only thing that might be an issue is if that rotor hat hits the bracing we have on our stock calipers, looks close.

[hahnmgh63]

S8prototype has covered this pretty well but I thought I would also throw in my observations of the RS5 scalloped rotors.
1. They are directional but left & right are the same so don't know if it really matters when inside of a spinning wheel.
2. They have 15 sets or 4 drilled holes compared to 14 on the OEM RS6 rotors.
3. OEM weight 26.1lbs (Not the 27.5lbs JHM claims for stock rotors) and the RS5 are 23.4lbs so a fair amount of weight savings but they are not the diameter of a wheel so not a huge rolling/spinning weight savings.
3. As S8prototype said, they do fit the RS6 hub/rotor/pad just as OEM.

[s8prtotype]

These with the forged volks up front makes me happy on the weight loss savings :)

[Korben007]

love the 380mm front kit but JHM is the only place that makes a matching rear kit

[Turbowned]

Another option I can't believe I never looked up before; Girodisc 380mm two piece front rotors:

http://www.girodisc.com/Girodisc-Front-380mm-2pc-Rotor-Upgrade-for-Audi-RS6_p_6543.html

In typical Girodisc fashion, they are quite expensive at $1,300. They offer front and rear 2pc rotors for my BRZ for only $1450 for all four ;)

[hahnmgh63]

Girodisc is just a couple of hours North of me in Bellingham, WA. Porsche club has a Tech session up there in a couple of weeks, if I'm in town I may just head up there. Maybe they'll give me a discount?

[Bigglezworth]

For all those eager to have 380's on the front and larger discs on the rear, I have to ask you - Just what exactly are you doing with your cars to necessitate this much brake?? Are you tracking it? Are you driving 250km/h+ and hitting the binders to keep from ploughing into the rear of a slower moving vehicle (i.e. what would occur on the Autobahn). IF neither, then just where exactly are the massive OEM set-up falling short for you? I have tracked my car many a time and had to perform the odd 225 km/h stop as part of passing a line of cars, but never have I had an experience whereupon the OEM set-up fell short (even for such a tank of a car). Good brake fluid along with a good quality set of pads eliminates brake fade.

[hahnmgh63]

For the most part I'd have to agree although I've always like to have a car that was over braked. Although since initial bit of the OEM with good aftermarket pads can't really be beaten, and heat sink is the only thing your really going to get from a bigger kit, then the Phaeton brake duct kit is what you should do first if you haven't. It will really help, even with track speeds to increase cooling without really increasing weight.

[kruat]

I'm gonna have to look up this pheaton brake duct mod. And, I think the stock brakes on these cars are great, but then I don't track it or drive super hard very often.

[RS8]

I'm tracking my car hard, but I can't have bigger than 365mm because of all my 18" wheels i'm using so I don't want bigger,
I only want to know which 365mm discs is best for hard tracking.

RS6 Zimmerman?
Phaeton?
RS5?
or?

So front brakes worked fine, but now I need new discs.


However in the rear I have had problems with RBF600 brake fluid boils! I'll have to change it after every tracking day, So in the rear I would be happy if I found bigger discs and brake calipers.

[s8prtotype]

For the rear i'll be using 4 or 6 piston calipers from Ceika (probably 4 piston with a bigger rotor)

They're developing a incorporated ebrake option for our C5 cars/rs5-rs6

16150

16151

Waiting on pricing for a few differen't options. But it's close to just the rotor prices alone for the stock stuff.....

M5 BMW guys have gave them great reviews so i'm down to try them and get some black calipers to match the front :)

[RS8]

Yes Ceika looks good.

But it will cost $1,612.00

For 356x28 full-floating with 4 piston with hand brake and racing pads.

[s8prtotype]

Gotta pay to play ;)

[audiprotn]

Zimmermans right now on sale on Amazon, $550 shipped

[Other_Erik]

Considering that's not even the cost of 4 Zimmermans with Hawk HPC pads, I'd highly consider that.

Meanwhile, I traded a pair of front Zimm's for a pair of front RS5 Wavey rotors, and picked up JHM 2-piece rears. Next time I have to do fronts will probably end up going with JHM 2-piece, but couldn't justify the extra $300 it would've cost this time around (even though I would've saved about that much next time around)

Did you read the thread regarding potential JHM issues? I wouldn't touch them until more reports on what was occurring surface.

That's what I was getting at, his idea of purchasing the fronts. With a mix of issues and mis-claimed weight savings, I just can't imagine purchasing them myself. Now for the rears not being under the same level of stress maybe they'll hold up better, who knows.

Dude. I had the same problem and tracked the shit out my rs6. Even with good pads I set mine on fire at Watkins. I upgraded to movit setup years ago and was very pleased with the results. After many friction rings and tires, I just upgraded to their full carbon carbon setup for this season. I am having the old setup refurbished by them and about to put up for sale if you are interested.

Soo have we figured out if any particular wavy rears are a direct bolt on? About to do some brake changes but only want the wavy rotors if I can have them at all four corners with no mods.

[mbagge01]

In regards to the last post, I soon need to replace my rear rotors. Has anyone successfully installed rs5 wave rotors on the rear. If so I would appreciate guidance on doing this in regards to parts needed, like spacing, if not a direct fit

[s8prtotype]

I have not touched the rear at all yet, but at this time I still think you need to do the 356mm rs7 rotor in the back for it to be worthwhile (if you're wanting to match the wavy fronts) as it's actually an upgrade. stock is 335mm right??

You'll have to play with caliper spacing... it's been done by one guy already but i think he just used something he made on his own.

[s8prtotype]

Went back and looked at the emails i had with a TTRS guy that did a conversion...

Looks like these guys in germany make a kit for everyones needs... although they don't have the wavy rears listed they have great prices and will probably send you the brackets only. even a 376mm rear conversion haha damn.. that'll look nice under the 19's!

So R8(all Years) rotors is the same as RS6 Font Right and left ? Plug and Play?

No, not the same. Yes, plug and play. C5 RS6 uses directionally vaned Left and Right rotors. Those cheap Lambo's and R8's do not (okay they sorta do, but just on the Left side...which makes the right side even worse than a radial vane type, as it'll cavitate or stall out air flow and overheat if driven hard... Damn bean counters vs engineers) :argue:

[UrS6]

UrS6, any details on the 390mm rotors. Which calipers, offsets, pads? Thanks,
Everything is stock except for the rotor and the caliper mounting bolts. . I made a spacer for the caliper. The only real advantage is that the mechanical force exerted on the rotor is further out from the axis of the wheel. It's probably negligible. But it was just something I wanted to try.

[s8prtotype]

BTW to update this thread as well... to use the RS5 Rear rotors you need a 6mm spacer behind the knuckle and caliper to space it properly according to canyon. :)
