Rs3 rotors question with a few extra grand laying around..

[sleeperwagon]

odd question but I am thinking I need to reduce weight now SO (and cutting carbs is not the answer): I have 38K miles (Crap I thought 28k) on original brakes and bought Audi pure protection platinum plus so my 1st brake job is free. Once I get them replaced I was going to take the stock front/rear rotors off and sell right away. already have BC Forged wheels.
Questions:
1) so the VW R has the same rear brakes as the S3. Are the S3 rear rotors the same as the Rs3? Asking b/c ECS has 2 piece rear floating rotors for the TypeR, same size. I don't need the rotor increase. ECS $500 vs. Girodisc $800 so the $300 would help offset something....
2) Girodisc front seem to be the best bag for buck (weight cost $1100 and 5.4lbs lighter each) unless someone knows any other options let me know. Know of the Brembo and Neuspeed options.
3) anyone have a good, logical reason not to spend a few grand on this? I figure I am stage1+ on E85, jumped on the Horsch GB a few weeks ago and just want more......
4) final question: if this was an option for you would you do this OR Eurocodes throttle body intake/IC pipe?
Cheers to 1st world problems.

AudiCare replaces brakes for free? I don’t think that’s the case

Neuspeeds front rotors are now $1038 on some websites(I was just searching), you might even get it cheaper on memorial weekend. If you are looking for weight reduction(unsprung weight) look into wheels instead but like you said, if you need rotors because your current rotors are thin then now is the best time to do it.

between the Throttle body and the inlet pipe it seems like the second yields more HP for less money(better hp/$ value). Ap racing also has light weight two piece rotors but they are more expensive.

No one's gonna comment on "VW TypeR". LOlL

It's the Golf R. Type-R is Honda model term.


Front rotors AP racing has a lighter solution for rotors than girodisc. About 9 pounds of savings and the best part being it'll work for stock brembo caliper AND their 6 piston AP radi-cal caliper when and if you want to upgrade the calipers. Just gives you options with also bring lighter.

He bought a service warranty, not AudiCare. He said it's the Audi pure protection platinum which is some crap the dealership makes a ton of money off of.

OP, did you do the rear disc upgrade yet?

LOL, I was going to say something but I rather stay quiet because I often misspell and I also have an auto correct that completely changes my words.. but yeah, I did noticed the VW "Type R".

Back to the AP two piece rotors, someone already raise the BS flag on the weight savings, not me but someone challenged the claims. look it up under Essex vendor on the RS3 subform). 18lbs weight savings seems too mucho me as well.

[Skunkwerx]

Went with Neuspeed 2 piece rotors and iSweep 1500 pads. Review and feedback to follow shortly.

Someone questioned the weight, but it hasn't been proven to be wrong. 9 pounds savings per corner does sounds pretty crazy. But AP racing is a legit performance brake manufacturer so we'll see.
Either way. the fact that you can do the AP racing upgrade in stages is what draws me in. Better than buying the Girodisc rotors then later if and when i want to ugprade calipers, gotta toss the girodisc for new rotors.
Invest in the AP racing rotors now and have an upgrade path to their calipers later. I've heard NOTHING but awesome things from people who track AP racing brakes.

Are there any decent rear brake upgrades with a better looking caliper that aren’t extremely expensive?

Actually, thanks to some info from Jeff, it has been.

AP Racing/Essex (TT RS, owner verified) - 21.6 lb/ea
Girodisc (RS3, per manufacturer) - 24.0 lb/ea
Neuspeed (RS3, per manufacturer) - 22.4 lb/ea
OEM (TTRS, per Jeff) - 27 lb/ea
OEM (RS3, per Girodisc) - 27.4 lb/ea
OEM (RS3, per Neuspeed) - 26.9 lb/ea


Also not true that you have to toss aftermarket rotors to upgrade the caliper. Brembo makes a replacement caliper that has been discussed on this site before that works with the OEM rotor.

Thanks Jeff for doing that home work for me. Appreciate that.

Yes agree my dumbass typed in Golf Type R, having an integra Type R as a kid and just getting back from cars and Coffee my brain was elsewhere

The audi pure protection was only $900 so I figured a complete brake job/wipers/battery was worth the cost. Dealer wrote down I could pull in the dealership at 59K miles (60K is limit) and ask for all 3 of those items changed and they will do it. That's why I am thinking of just scheduling a brake job now. I thought it was worth it to me.

ECS Tunings S3 and Golf Type R (Kidding...) rear floating rotors they state : ECS 2-Piece rotor weighs only 12.75 lbs on their website for $505. That seems like a steal. I'll order them and let everyone know if they fit.
Thanks everyone

[Jeff_Jeske]

The front rotors for the TTRS and RS3 have a different offset but Giro has options for both as does Essex Racing.

The rear rotors are the same for both platforms as well as those noted above.

The OEM rear rotors are plenty good and only require a pad/fluid upgrade to become track ready.

If you want to keep braking performance while reducing weight then a two piece option may make sense. The Golf R option seems to be an inexpensive way to accomplish this.

[Skunkwerx]

Another factor I looked at when I compared Girodisc and Neuspeed was the aluminum used for the center hats.

Girodisc - 6061-T6
Neuspeed - 7075-T6

Found this article comparing the two types: (https://metalpress.onlinemetals.com/...luminum-alloy/)

From a spec standpoint... it was one of the reasons I picked Neuspeed. I don't have any brand loyalty for either company so I was unbiased (admitted newbie) with brand.

[OE2]

also look at the cost of replacement rings when ever you are buying a 2-piece set up. the Essex replacement rings are cheaper than others even if the initial cash outlay is a little more.

Great info Skunkwerx! Thanks for sharing. Good to know that Girodisc is lower quality.

[RSKYBET]

Great info Skunkwerx! Thanks for sharing. Good to know that Girodisc is lower quality.

Sorry but this isn't quite accurate. 7075-T6 actually weakens as temperature goes up at a much faster rate than 6061-T6. In fact, at higher temps, 6061-T6 actually has higher yield strength than 7075. I used to have some graphs that illustrate this but I'm not sure where they are at the moment. With that said, I'm not sure how quickly a rotor hat saturates with heat being convected from the rotor ring and conducted through the fasteners.

Edit: I found this with a quick Google search, but it's 2219-T6 and 2618-T6 vs 7075-T6. I believe 6061-T6 is somewhat similar to 2219 in this behavior as they are pretty close in initial yield strength.

Understand your point and this is probably too much math and science for a Tuesday. :)

But given the baseline mechanical properties of the metals...even with taking temps into account...are the properties of 7075 stronger and therefore failure would be still after 6061?

6061 – Properties
•Ultimate Tensile Strength 45000 psi
•Tensile Yield Strength 40000 psi
•Fatigue Strength 14000 psi
•Shear Strength 30000 psi
•Hardness, Rockwell 40

7075 – Mechanical Properties
•Ultimate Tensile Strength 83000 psi
•Tensile Yield Strength 73000 psi
•Fatigue Strength 23000 psi
•Shear Strength 48000 psi
•Hardness, Rockwell 53.5

Granted we aren't launching our RS3 into space... even though the Malaka's and Iroz might. At this point... I'm trying to be a metallurgist and understand more.

Both brands and others have good reputations and I'll share my experience with the Neuspeeds. I might do a track day in the future and attempt to make them fail. :)

I found this graph below for 6061-T6 (red line). So for example, compare the yield strength between the two materials at 200* C. This is an imperfect comparison because of two different sources, but it gives the general idea.

Thanks RSKYBET. Appreciate the additional detail.

Back to the topic of RS3 rotors, I had Neuspeed 2 piece rotors installed recently and thought I'd give my initial impressions.

http://www.neuspeed.com/9943lr-neusp...ing-rotor.html

Weight savings covered in the posts above, however Neuspeed claims a 9lbs weight savings for the pair over stock.






Went with iSweep 1500 (Street) pads.
http://www.neuspeed.com/374/4/0/3776...nt-isweep.html




Pads do not have wear sensors however came with single resistor plug to avoid CEL and cutting and looping OEM sensor plug. (Not pictured)

After a few days of driving, I'm pleased with the quality of these street pads and rotors. They feel equal to OEM and after bedding, I've had the opportunity for a few hard stops and the bite is smooth, strong without significant fade. Dusting is equal or less than OEM thus far. No squealing.

I know the veterans and the informed on this forum could do this stuff on their own but I'll plug for the shop I used...

For SOCAL guys in South LA or OC.... Auto Union Tuning in Huntington Beach is a shop worth checking out. Ask for Jimmy. He is very friendly, helpful and the techs are qualified informed former Audi dealer techs.

I finally got around to installing my ESSEX RACING / AP J-HOOK ROTORS:

[sleeperwagon]

UPDATE: so with the Pure Plus Protection Program the first brake job (Pads/rotors) is free but the pads need to be under the 3mm mark for the dealer to be covered by Audi. Which is OK and I understand. My problem is: I almost have 40K miles on my car and in April during the Oil Change I had 60% front brake life and 70% rear.
HOLY SHIT are these brakes great and wearing slow. At this rate I will not need new brakes til PAST the flipping 4 yr/60K coverage date...
hate to LOL but do I need to drive with my wipers on and left foot brake the remaining 20K miles? few track days? etc. I thought for sure our Brakes were not capable of 60K miles but I guess they are, at least when no track time is involved.

Which version of rotors do you have? Mine are the third version and I'm happy with them. They've been on the track and multiple trips to the drag strip. I think Audi finally got it right. Maybe, hopefully.

[sleeperwagon]

that sucks even more. how many track days and drag strips is it going to take? not sure on version...mine is a 2018 built end of 2017 so should be an early version

I'm not sure when they changed to version 3. Mine have random holes drilled and the inner- and outer-most are only dimples. Try poking a chopstick thru all the holes in a group. I think the previous version had random holes but were all drilled all the way thru.

I think you should drive normal and enjoy the car as is. The brake pads are super easy to replace in the event that you wanted to go more aggressive or shift to a pad that creates less residue. If your rotors look like the ones I posted up above I don't think you'll have any issues as those things are heavy duty. Just look at the thickness of the rotors compared to my two piece rotors. You should feel good that your car is running in tip top shape!

I was in the market for new front rotors and just pulled the trigger on some from AP racing. They were awesome to deal with. Can’t wait to get them on!

Hey guys I want to give you an update on brakes. I finally got my front brakes done, I am going to copy/paste my response and I will post it on bold letters on other brake topics so that I can help other buyers making a decision. so like I was saying, I decided that it was time to upgrade my front brakes, I had 17000 miles as of Oct 10 2020 and my brakes were shaking badly, so much that if I had $hit laying around on my the center console like keys, coins, drinks, everything would shake.


I decided to go with Neuspeed rotors and Carbotech 1521. My sources were modded Euros for the rotors and the price was $883 shipped for both rotors. For my pads I went with Paul at Supreme and I paid high $200 shipped, they shipped directly from the factory.

As far is weights, the stock rotors were 29.2lbs and the Neuspeed were 22.2 lbs. Please understand that each bathroom scale is different, I have a German digital scale and to be fair I weighted the rotors several times back to back and in different positions (vertical, horizontal), the final number was always the same 7lbs of difference.

Once again I also want to be fair and tell you that I heard that there are a few versions of rotors from the factory, I read that late 2018 and in 2019 they "addressed" some warping issues with the design. My car was ordered on 22 Feb 2018 and it was probably built around May 2018. As per the neuspeed, I don't know if they made any newer versions but what I am trying to point here is the massive weight difference, 7 LBS per corner.

I am still doing the bedding and breaking in the brakes. Obviously the vibration is now gone. If you are a nerd on weight savings I think that the Neuspeed will make you happy, compared to what I seen out there they hit at least two check marks for weight and price. Anyways, I wanted to share my post because I have been actively participating on brake topics for a solid year. Below are some pictures that I took:

[S3DUDE]

Actually, thanks to some info from Jeff, it has been.

AP Racing/Essex (TT RS, owner verified) - 21.6 lb/ea
Girodisc (RS3, per manufacturer) - 24.0 lb/ea
Neuspeed (RS3, per manufacturer) - 22.4 lb/ea
OEM (TTRS, per Jeff) - 27 lb/ea
OEM (RS3, per Girodisc) - 27.4 lb/ea
OEM (RS3, per Neuspeed) - 26.9 lb/ea


Also not true that you have to toss aftermarket rotors to upgrade the caliper. Brembo makes a replacement caliper that has been discussed on this site before that works with the OEM rotor.

Sent from my iPhone using Audizine

So I went ahead and pulled my other digital scale just to compare the weights again and one of my scales says 29.6lbs for the OEM rotor and the other scale says 29.2lbs. the Neuspeed rotors weight 22.2 lbs. What I found interesting is the actual design of the rotors, my early 2018 RS3 hats looks completely different to the ones advertised by Neuspeed making me think that I have the first version rotors (V1). What I am saying is very important because I am providing an independent proof with my own source of pictures and weights with more than one scale.

It appears to me that if you have a late 2017 RS3 or early 2018 RS3 or TTRS you will be saving an additional 2 lbs per corner just because of the design from the factory. Please take a look at the pictures of the rotors on ECS website, the hats looks different than my hats. Link below:

https://www.ecstuning.com/b-neuspeed...lr-space-~neu/


That explains why Neuspeed only claims 5.4lbs weight savings because they compared them with the V2 rotors. If they were to compare them to the V1 rotors it would have been 7 Lbs weight savings as I just proved.

[DrBoost]

Good info in this thread. I just bought my RS3 and have been researching info on upgrades I want to do with my car. I am planning a few open track days and overheating brakes seem to be a really big issue with these cars I would like to address beforehand. I am considering the Neuspeed rotors vs 034, Essex and Giro. Would like to get your feedback on the neuspeed pad combo you selected and how they performed on the track?
Thanks

[Arelax]

Just an FYI to add to the discussion

Did my Front brake pads/rotors recently.
2018 RS3

When I pulled my oem rotors off, they weighed 29.6 lbs each
The Girodisc rotors weighed 22.0 lbs each

running Girodisc rotors + Carbotech 1521 pads. Havent driven aggressive yet, but pads feel good(~750 miles on them), very similar feel to stock. Brake dust is off the charts, but I believe they say it will be bad for ~1500miles until theyre broken in.
