ECS Slotted rotors vs StopTech

[Elderan]

So I order and already have the ECS Slotted Rotors (https://www.ecstuning.com/b-ecs-parts/front-slotted-brake-rotors-pair-345x30/8k0301mslgmtlra/) front and back, they are planned to put on in a few weeks.

I have two concerns, how do these stack up against the StopTech (https://www.ecstuning.com/b-stoptech-parts/front-slotted-brake-rotors-pair-345x30mm/126.33124slkt/) version? Also the ECS are pretty silver looking. I ordered and installed some new Harman wheels which are dark gray and I can see the rotors clear through now and I am concerned the brighter silver might look weird against the gray wheels.

[waxxonMTL]

with all due respect to ECS, they are a reseller.. not a brake manufacturer.. I don't know why ppl can believe a reseller can stack against a real legit brake manufacturer !

[whiped]

I highly doubt ECS actually makes them.

Rotors should look great behind your wheels [up]

I am sure this is the case, but I could not find any other way to reference them by.

That was for Waxxon [:)]

FWIW, the people I have seen with ECS rotors seem happy with them.

totally agree ! I'M sure they don't, but I bet it doesn't come from stoptech/brembo factory either lol.. let say it comes from zimmerman factory.. might as well stick with zimmerman for cheaper then isn't ?

[waxxonMTL]

One of my favorite brand is DBA or Brembo. Unfortanely, DBA don't make any rotor for our application but brembo JUST came out with a rotor option for the 345mm option which I should be ordering in th enext few months when mine is due (unless something else came out like 2piece brembo or dba application)

ECS branding has to be good for at least 5 HP.

I've had slotted ECS rotors for 6 months. They perform well on my dd, but one thing that bugs me is that their internal vanes lean differently for each side.

Yes, the slots are directional, but the internal cooling vanes are slanted in the same direction for both left and right sides. So once installed, one side's vanes lean one way (forward, for example), and the other side's the other (backward).

Minor annoyance, but it bugs me. Why bother slanting the vanes if you're not going to do it correctly? (Cost savings, is the answer)

[Elderan]

Thanks for the comments, just wanted to make sure before I went ahead with the install.

Cost savings is right. I can't fault ECS (and their manufacturer) too much though, because Audi OEM does the same thing. Even on the $160k R8 V10, the same rotor is used on both sides, meaning one side is not getting full cooling...

[-leman-]

Yeah, the funny thing is they weren't like that in c5 rs6 times. It had different left / right rotors, which by the way are interchangeable with the newer non-directional rotors...

[Johnnycash]

i have ecs drilled/slotted on my fronts, and stoptech cross drilled on the rears. because racecar[drive]

more importantly akebonos all around!

[SR7D1]

Two sets of ECS rotors on two different Audi's, A4-slotted, S5-slotted & drilled. Both cars saw 3 days of road course racing, no issues at all.

New brakes this Fall, Stoptech ST60 and trying out Adams rotors for the rear. You should be fine with the ECS. [up]

Every single aftermarket OE replacement rotor is manufactured the same way. The only brand I know of that redesigns the internal vanes is StopTech and they are just straight vaned.

Though our 2-piece rotors are directionally slotted and internally vaned! [up]

That's not what it means. Which direction the slant of the slot is in has little to no affect on the cooling potential. The only thing that matters is the direction of the directional vanes, which you'd want pointing toward the rear of the car.

Are you saying that the rotors you use have directional vanes that are both pointing the same direction? It probably won't ever really make a difference, but they should either be created with no slant in the vanes, or each side should be made differently.

Yes, all the Audis, even the RS cars, use the same rotor left and right, including the vane direction. So yes, one rotor does get less cooling than the other. Most of the time no issue, but a little disappointing that its a half assed job by Audi, even on the high end S and especially the RS cars.

The OEM rotors on RS4's are internally vaned, but they're straight vanes, so they're not directional.

Please read next time. I never said anything about slots- only the internal vanes. One side does in fact receive worse cooling.

Obviously Audi SHOULD make them that way, but they do not.

oops

[waxxonMTL]

also, as i said earlier, brembo xtra was released in europe.. these might be directional too since they are a performance rotor.

GYRO DISK are directional internally, to pump more air. I have no association with them other than happy customer. http://www.girodisc.com/Technical-Info_ep_45.html

those may be, but i can confirm the ones we talked about a few weeks ago are not directionally vaned.






I bought the Brembo OEM Replacement blanks from Amazon. Prime has them super cheap.

Front:
https://www.amazon.com/gp/product/B00CJO9U74/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
Rear:
https://www.amazon.com/gp/product/B00D3DJAD4/ref=oh_aui_detailpage_o09_s00?ie=UTF8&psc=1

I don't see the logic buying a slotted or drilled rotor unless you upgrade to a BBK. For the price these brembo blanks cannot be beat.

$303 shipped to your door for all 4 rotors? The rotors i received are made in italy too. These with Akebono's from amazon made for an extremely cheap while maintaining high quality 4 wheel brake job.

it's different. new release from 3rd quarter of 2016 .. not sure if I will go with or without drill. I usually prefer blank or slotted, but I like to believe brembo did their class and when they say the drilled one offer better performance than the blank one than it really does lol

you can get fronts for about $315 USD shipped on ebay it looks like

honestly i think its only worth it if you track or really hoon the car daily. i can get all 4 of the regular rotors for the same prices as the 2x fronts. they look nice though, and the only correct directional vaning unless going 2 pc rotors.

the akebono euro ceramics are a massive learning curve coming from stock/oem pads
instead of the instant on/off initial grab of the oem i have a nice progressive pedal feel, which i tend to prefer

upgraded performance? not sure. about 1/3 of the cost of OEM parts while having zero brake dust and italian forged rotors? you betcha.

i daily drive my car and canyon run on the weekends. so far they have worked perfectly for my needs.

That's the rear rotors, which are directional. The fronts are not.

No, these are fronts.

You're right that the B7 RS had straight vaned, however the new cars do not. Mk2 TTRS, RS5 (normal and wave), R8, B8 RS4 etc are all like this.

Hello everyone, Quick question. I have a 2015 B8 Q5 TDI with 330mm rear rotors. Stop tech makes a set ‎127.33137L which indicates Left. Does anyone know if Left and right are the same? From what I remember from the past, having bought Zimmermann, they were both the same. Any thoughts? Thank you

It is possible that the internal cooling vanes are directional. Which would make them side specific.

My lady's factory BMW front disc's are this way.

[Nillious]

I don’t think it matters what direction the vanes go. On way will pull air from the inside out. The other from outside in. Just like if you reverse a fan. It still moves the same air just in a different direction.

[carguy19]

ECS SUCKS. They use to be great years ago but all they care about now is profit margins. I would never buy one of their parts they manufacture ever again. Its cheap China BS.

Their customer service is horrid.

I have the painted and coated Zimmerman rotors on my car and they are fantastic. You don't need slotted or vented rotors unless you are tracking the car.

[f1torrents]

ECS is by far the worst VAG parts company around.

Service has dropped off.
Parts are overpriced.
In house parts are of ebay quality.

I don't even consider them anymore. Pure garbage.

There are many others out there nowadays.

DAP
FCP Euro
Rockauto
German parts - Canada

This is incorrect.

The air is meant to go from the inside of the hat to the outer edge of the disc.

Look at F1 brake duct for examples.

I agree.
I finally got all their brake components off my car.
