What kind of of price range are we looking at for the two piece rotors? I need to do my rears soon but could do fronts as well. Shipping would be a killer to me though in Ireland
Those rotors will be available soon on our website. However if anyone wants them pre-release give me a shout!
Oh by the way… 38lbs for a used worn out rotor. I weighed in a new rotor at 39lbs ;D
Price? My car’s heading over to you guys in a couple weeks, if they don’t cost a fortune I’d be happy to give 'em a go!
Edit: after a quick google search, it appears that I’ve got EBC GD Sport rotors on all 4 corners currently. If I understand correctly, these are crap. So I’d definitely be ok with an upgrade.
$795 for the pair!
Alright let’s see what the rest of my bill comes out to first ;D
It’s definitely worth it. That unsprung weight reduction is huge performance gain.
No doubt - I just don’t want to get stuck with a bill I can’t pay 
I’m not sure how much work my car is going to need or what kind of bill I’m looking at, and since rotors are easy to add later I’ll wait til I know what kind of damage my wallet is taking first
We can always work with you. Just let us know!
I’ll talk with you guys about everything on the 11th 
Getting excited! Anyways I’ll stop hijacking this thread now lol, don’t want to drag this too far off topic
Edit: Moved to the actual performance thread 
Wahoo, that thing sounded awesome. still loud as hell all the way out at at the finish line. I still have no clue how my car sounds from outside, I’ve always been sitting in the driver’s seat when it’s on the road. Some day I may try to set up a decent camera for a drive-by.
It might be a good idea to move these into the thread talking about the cars actual performance. These once again continue to back up what we have been saying all along. That these cars are 14-13.8 second cars
The one S6 had no cats and a full catback exhaust from what I remember
The S8 had a catback exhaust and I believe APR tune on race gas. Both were terrible when it comes to better results from stock
The good news is I hear the JHM tuned S8 CRUSHED those times by a healthy margin.
That is a MASSIVE weight savings. Hard to believe there is that much weight to be shed from just the rotors. If you added some LW wheels as well, you’ve done as much as a tune and exhaust does on most NA cars performance wise.
Can’t wait to see what the performance numbers are for the build. Glad to see some love for this awesome platform.
Just wanted to chime in hear with respect to the carbon cleaning/intake removal.
I had the oil valley leak from the base of the oil filter housing to block. It’s a $2 gasket, and I think it’s worth adding to the list of things to do while the intake is off.
Audi has revised this gasket too it seems.
Otherwise thanks for all this info!
STILL waiting on actual numbers for this cars 1/4 times!
I know, so sorry guys. When I have customer projects; like exhaust or other builds, I make sure to handle those guys and their projects first. I make sure all my time is on those projects, it leaves little time for updates here. The good news is I just finished our last project and I’ll be able to get back on these updates.
I’ll make sure to speed this along. Next, up, I’ll post about the read brakes and then the exhaust. After that the finish line with the actual track results.
This week we drop another 10lbs off the rolling weight of the car with the JHM rear rotors and I walk quickly through what you’re going to need to do with vag com to be able to get the rear breaks off.
Yes, you read that right. You can’t do rear breaks on these cars without the help of the computer. So, when you’re doing brakes keep that in mind. You’re in good hands here though, I post at the bottom on what you’re going to have to do to open the rear brakes.
Now on to the thread.
I did the front brakes and dropped over 30lbs between the two of them. Each side I was able to drop 15lbs with the JHM LW rotors.
With that big impact, I thought it would be time to drop a little weight from the rear rotors. Again using the JHM rear rotors.
These not only look great but they function better than the OEM units and they weigh 5lbs less each.

With the JHM rear rotors, you’re knocking off another 5lbs a side. For rear rotors, that’s a lot of weight. You normally don’t see that kind of weight reduction in rear rotors. The front brakes do the majority of the work so the rear brakes don’t need to be as big. Still, it’s a good area to shave weight when you can.

With all this weight savings I actually saved a ton of money. Usually to get these kinds of weight savings you have to get light weight rims. Since the S8 comes with 20" rims stock. It’s kinda hard to find nice light weight 20" sport rims.
Oh, and if you’ve ever wondered how much the OEM S8 rims and tires weigh.

That’s a lot of weight for rims and tires.
Now for the technical part of the post. Most of you might not know but you can’t just jump onto the rear rotors like you can the fronts. The rear rotors with the electronic parking break require the use of a computer to unlock and open the rear brake caliper.
If you’re a DIY’er 90% of the brake job is going to be the same the rear brakes come off easy without much fuss but when you need to open the caliper you’re going to need a computer. If you have a vag com I’ll show you what you have to do.
EASY STEP 1
Open vag com and select the “SELECT Control Module” option

STEP 2
Select option #53 - Parking Brake
http://audirevolution.net/addons/albums/images/665717865.jpg
STEP 3
With the Parking Brake controller open click on the - 04 Basic Settings
http://audirevolution.net/addons/albums/images/853060578.jpg
STEP 4
In Basic Settings open the drop down menu and click on Open Rear Parking Brake
http://audirevolution.net/addons/albums/images/860157509.jpg
STEP 5
You might have to still help open the piston manually. Clicking on Open Rear Parking Brake doesn’t necessarily open the piston all the way. You might have to open it to the specific spot you need to place on the pads. Now is when you would push back the piston on the caliper as far as you need and put in the pads. After the pads are on and the caliper is back on and in its place. You’re ready for the next step
STEP 6

That will get you all set. Some people like to do the Parking Brake Function test. I never found a need for it. That’s there if you have an issue and you’re checking the function of the system.
This walkthrough works for most cars with rear parking brake systems.
Now with all the weight lost from the JHM Rotors, you’re car will be transformed into a lighter fighter. All in all, it’s a mod worth doing. The rear rotors don’t get changed that often so this mod should last you years and years and years before you’re going to even need to think about replcement of the rings.
More go fast mods and a great walk through. I already posted the one thread you made in the S8 section about doing the brakes.
