      Review & Installation Video

      If you're looking to take the brakes on your 2015 and newer GT or EcoBoost Mustang to the next level, then you should certainly consider adding a set of the Baer EradiSpeed Plus Front Rotors that we're talking about here today. Now, this time the Baers will be the only set in the category to offer that two-piece design or construction and will be offered in two different sizes. One for Brembo owners and one for the standard GT and performance pack EcoBoost owners. Your price point will, of course, depend on your selection in that regard, but it's gonna start at that mid-$700 level for the smaller non-Brembo option and land right around a 1,000 bucks for the larger Brembo rotors. Now, installing a new set of rotors is pretty painless in the braking world, so I figure soft two out of three wrenches on the difficulty meter here, about two hours or so to get everything swapped out.If you didn't know, Baer is certainly a major player in the aftermarket braking category and have been producing some pretty killer components for well over 30 years now, designed to help you and your ride stop much faster. Now, with that said, the same can be said for the EradiSpeed rotors here. So, what do you say we talk about them a little bit more?Right up front, guys, these are going to be a direct swap with the factory components and are designed to be used with your factory calipers without issue and, more importantly, without modification. Secondly, and this is a biggie, gang, so pay attention here. And that is the fact that these will be offered in, again, two different sizes. The larger 15-inch option will be for the performance pack GTs equipped with the Brembo calipers whereas the slightly smaller 14-inch discs that we just so happen to have here on the table will be for those non-Brembo GTs along with the Performance pack EcoBoost Mustangs. So, again, I know I sound like a broken record here, but I just don't want you guys to order the wrong set for your ride. Pay attention when ordering. And yes, we are saying "set" because, obviously, these things are sold in sets of two for the front end of your S-550. But just a heads up, guys, Baer does also offer a matching set for the rears which owners can also grab here on the site, if you're looking to tackle all four corners at once.Now, granted this will be a pricey upgrade compared to a set of PowerStops or something along those lines, but you have to keep in mind, again, these are gonna be the only rotor options that you can grab currently on the site that will deliver that coveted two-piece design. And why is that such a big deal? Well, two-piece rotors have some pretty significant advantages over a standard one-piece option, the biggest of which being weight savings. Now, instead of a one-piece cast iron design, the Baer two-piece is going to combine an iron friction surface, that's basically the ring there, with a billet aluminum hat, that's basically the part in the middle. And then they're gonna factor in all of that drilling which, altogether, will help shed roughly 10 pounds per corner of rotational mass, by the way, which is never a bad thing.Secondly, that aluminum hat in the center will act as a heat sink of sorts and in turn help keep the brakes a little bit cooler while also not allowing that heat to transfer to the hub of your Mustang and, therefore, the wheel bearings which in theory should help prolong the life of the bearings themselves, especially on cars that see a lot of track time. That's not really a big issue for most street cars but, if you're tracking your S-550 frequently, heat can be an issue over time. Finally, you have to admit they do look pretty killer to boot.Now, the only real downside of a two-piece rotor is essentially going to be the more expensive price. But there really is not comparing a traditional one-piece option to the two-piece or the EradiSpeed that we have here. But along with the benefits we just talked about, the Baers will also include the cross drilled and slotted design which will also help with cooling along with expelling the gasses produced during hard braking and help keep the pad surface clean at all times. Now, the rotors had been directionally veined and that's that little detail in between the friction surface and that's also gonna be crucial to cooling and help promote air movement through the rotor at all times.We did also briefly mention the billet aluminum hats here, guys, in the center, and those have been secured, by the way, using aircraft or aerospace hardware, best of all, no safety wiring involved and they've already been assembled for you. So no worrying about that. Everything has been red-Loctited and it's essentially ready to rock and roll right out of the box.Now, as far as your install is concerned, well, like we mentioned earlier, swapping rotors in the brake world is probably one of the easier things to do. Simply lift and support the car, unbolt the wheel, unbolt the caliper, remove the factory disc and replace it with the Baer that we have here. There's no need to disconnect any brake lines and, as a result, there's no need to bleed the system or anything else that would otherwise stretch your install. So, because of that, I figured soft two out of three wrenches on the difficulty meter, couple of hours to complete or less, from start to finish. And just make sure jack and jack stands are on hand, lift, whatever you have access to and a basic socket set.So, in closing, if you're looking to upgrade to a two-piece rotor without fully committing or stepping into an expensive big brake upgrade with all of the trimmings, then the EradiSpeeds here, from Baer, will be a nice compromise that will keep the install easy, thanks to reusing the factory calipers and hardware.

      Brake Rotors for Every Situation. Providing a big improvement in the stopping power of your 2015-2020 Mustang, the Baer EradiSpeed+ 2-Piece Brake Rotors, Front Pair feature a vented design that stays cool and brakes hard even during performance driving. This cooling is provided by curved internal vanes that pull air strongly through the disc interior. This American-made part is also made with a two-metal construction that saves weight without sacrificing power – quite the opposite, since its cross-drilling and slotting enhances stopping power and reduces stopping distance in both ordinary and wet conditions.

      Cast Steel, Machined Aluminum Design. Tough cast steel is used for the rotor bands in the Baer EradiSpeed+ 2-Piece Brake Rotors, rugged parts 100% made in the USA at Baer’s Phoenix location. The steel is mill-balanced to ensure stability, lack of vibration, and quietness, and zinc-plated for extreme rust resistance. The separate aluminum hat is machined out of 6061-T6 aluminum, anodized black, and bolted to the rotor band with NAS stainless steel fasteners. The result is a high-grade, low-weight brake rotor with durability to spare.

      Quiet Running, Fade Resistant Rotors. Shimmering bright and metallic through your Mustang’s spokes, the Baer EradiSpeed+ 2-Piece Brake Rotors provide an aesthetic upgrade alongside the strong improvement in braking they offer compared to stock. The double rows of cross-drilling and the slots act together to keep the pad free of glazing and maintain the surface of the rotor in a clean, high friction condition. Venting inside the rotors features directional vanes that curve in the direction of rotation, so that when the rotors spin, they pull air in through the “eye” of the hat and expel it at the edges. This carries away heat from the metal, as well as drawing brake dust and water away from the rotor surface through the cross-drilled holes.

      Setup in 120 Minutes or Less. The Baer EradiSpeed+ 2-Piece Brake Rotors are made to bolt on directly and easily, with very little hassle. Installation requires no bleeding of the brake lines in preparation, making the task even quicker.

      90-Day Manufacturer’s Warranty. The Baer EradiSpeed+ 2-Piece Brake Rotors is covered by a 90-day limited manufacturer's warranty.

      Application. These 2-piece Baer EradiSpeed+ Front Slotted Brake Rotors are specifically designed for use on 2015-2020 Standard GT, Performance Pack GT and Performance Pack EcoBoost Mustangs equipped with the performance pack option only. Driver and passenger side rotors are included. Please choose your model from options listed above.

        Great Rotors

        I have the Fronts for the premium GT Brembos and a set of rears. These make a big difference in stopping power, responsivness and overrall break performance in addition to looking 10x better than any other rotor! I highly recommend.

        Matched With Baer Calipers

        Matched these rotors with Baer 6 piston deep red callipers with black lettering on all four corners, the look turns heads, only Baer makes 6 pistons for front and back. It put my magnetic grey 2015 GT premium convertible into a whole new league. From 100 MPH this car now wants to stop. Stopping power is unbelievable. Paired with summer Michelin PS4S, 255 and 275, 19 inch 40 front and back, safety, handling and control went to WOW. Thank you AM

      Helpful (2)

      Do these rotors have the ventilation holes on the back side? So we can add brake cooling ducts.

      • The Baer EradiSpeed+ Brake Rotors will have openings to the vents in the rotor on the back side, allowing for excellent cooling when used with a brake cooling duct setup. .

      does this fit the 2019 mustang EcoBoost? and is it the same size rotors as the oem one?

      • This will only fit the EcoBoost with the Performance pack, as these are bigger than the standard stock EcoBoost brakes.

      2019 Mustang GT Performance Pack (Seeking fitment for this car) Q1. Is this Eradispeed front a 14"? or a 15"? Q2. I ordered Brembo 4 Pistons Kit for the rear. Can the Eradispeed 14" front or 15" front fit the rear? If not, do I go with the 13" rear? best regards, Charles

      • This kit is for a 15-19 EcoBoost Mustang with the performance pack so the rotor size would be 14 inches and all performance pack GT's and EcoBoost Mustangs came with 13 inch rear rotors.
