ECS Tuning-Audi

Light on weight. Long on looks. The new ECS Tuning Engineered 2-Piece front brake rotors combine the natural advantages of a cast iron braking surface with the weight savings and rapid heat dissipation of an aluminum hat.

Cast iron-gray and durable matte black hats create an eye-catching contrast that accents painted calipers behind open-faced alloy wheels.

These beauties have all the extras: black anodized hats, cross-drilled and slotted brake faces, and unlike OEM, directionally vaned rotors for better cooling and heat dissipation over stock.


Features include:

• Aluminum hats: To save weight, each rotor ring is bolted to a lightweight aluminum hat made from high quality 6061 aluminum, and hard anodized with an attractive matte black finish that is both durable and corrosion resistant.
• Gray cast iron rings: Long known for its wear resistance and stable friction characteristics, FC-30 cast iron is favored for brake rotors due to its ability to absorb and dissipate large amounts of heat.
• 2-Piece construction: Conventional rotors are made from 1 solid block of cast iron, causing them to be typically quite heavy and not able to quickly dissipate heat. ECS rotor hats are bolted directly to the rotor ring for massive weight savings and better ability to dissipate braking temperatures.
• Heat treated: Heat treating further reduces the tendency for rotor cracking by reducing internal rotor stresses.
• Directionally veined: Conventional A3/S3 rotors are curved-veined only going one way so heat is dissipated much faster on one side than the other, and rely on an inefficient centrifuge-like effect to evacuate hot air from within the rotor. ECS 2-Piece rotors feature directionally curved veins, directional veins accelerate air away from the rotor at a higher velocity, leading to consistent, rapid cooling on both side equally.
• Drilled and slotted: 2-Piece rotors are cross drilled to promote cross ventilation for improved cooling as well as slotted to clean brake pads, carry away water and brake dust and to reduce rotor face temperatures to minimize brake pad gassing. Cleaner and cooler brake pads result in faster, more consistent stopping. Drilled holes are chamfered while slots are machined with a ball end mill - both to prevent cracking that may be present on improperly machined rotors.
• Overall weight savings: S3 Front Rotors - 5.15lbs per rotor. A3 Front Rotors - 3.35lbs per rotor. S3 Rear Rotors - 3.65lbs per rotor. Lighter rotors reduce unsprung weight and rotational mass to improve both braking and suspension performance.
• Manufacturing quality: Non-friction ring surfaces, including internal vents, are painted to resist salt and other corrosives. Ground braking surfaces ensure rings run parallel, and pads bed easily.
• Includes ECS Stainless Rotor Set Screws to eliminate rusty factory fasteners

Lightweight. Heavy Hitter.

Let me know if you have any questions.

Are the A3/S3 front rotors the same size?

oblique

No the A3 front rotors are 312x25 & the S3 front rotors are 340x30
A3 rears 272x10 & S3 rears 310x22.
I have been considering upgrading my front brakes on my A3 to the S3 setup (Calipers/Caliper carriers/340x30 rotors) Don't know if it's worth it though or if I should just paint my calipers & carriers and get these or similar rotors.

Been eyeing some brake upgrades, but wasn't sure if it was a simple swap over from S3 to A3 rotors. Looks like the full setup is needed, bummer. Getting a little larger in the back would be nice as I'm already 90% positive I'd get a BB kit for the fronts.

Yea me too, Well technically I think to upgrade to the S3 setup you just need the rotors and caliper carriers. The A3 caliper is the same part number as the S3 caliper but it doesn't come painted red or black and from pictures it doesn't seem to have the holes or indented lip to clip in the S3 caliper name plate. I thought about going this route but then you have to paint the A3 calipers to match whatever color you get the S3 carriers (red or black) and then I like the S3 caliper name plate since I was thinking of painting over the plate and putting a caliper decal over it, maybe the 4 rings or quattro. So I might just go with the S3 setup (Calipers/Caliper carriers/340x30 rotors).

I would love to get a BBK like stoptech but I know I probably will never track my car and also for the price of just a stoptech BBK alone (which is only for the fronts) I could convert the front & back brake setup to the S3 brakes.

Will these rotors work with stock calipers/pads?
