      Video Review & Installation

      Hey, everybody, I'm Justin with and this is my quick overview of the Power Stop Evolution Cross-Drilled & Slotted Rear Rotor kit available for your 2015 and newer GT and EcoBoost base or performance packed Mustang. This quick overview is gonna cover my thoughts on the benefits of running Power Stop's rear kit for your S550. What you're gonna be looking at as far as construction, and then basic design and then finally what it takes to get these guys installed. And speaking of the install, you're looking at a soft two out of three wrenches here on the difficulty scale. Obviously, the rear of the car has to come up, the wheels have to come off and there are a few steps involved, but we will cover that a little bit more in detail later on. The Power Stop kit that we have in this video should appeal to the S550 owners out there who have already upgraded their front brakes to the drilled and slotted variety and are now looking for a very affordable set to match for the rears. Now in my opinion, these things are gonna look killer behind your stock or aftermarket wheels, but there are some additional benefits that these things are gonna bring to the table as well. But first, let's talk about some of the benefits you can expect when checking out the Power Stop kit. But before we go any further, I do want to be brutally honest here, the rear breaks in your Mustang are gonna be more of a support system for the front. The front breaks are no doubt gonna be handling most of the heavy lifting but that doesn't necessarily mean you should neglect the rears. You don't want to skip leg day, and you don't want to leave the rears totally stock if you're putting a bunch of money and effort into the fronts. But with all that said, let's dive a little deeper here with the Evolution Rear kit. Now, these guys actually start out as a G3000 grade cast iron blank. They then get the slotted and drilled treatment using that precision machining. And finally, everything is coated with that durable zinc plating. Now this is cool because it's just gonna help reduce any corrosion over the years, help the parts maintain a nice bright silver finish. Now, the only thing that you have to keep in mind here, the friction surface, basically where the pad is gonna grip the rotor, eventually that zinc plating will wear off as to be expected but it's still gonna maintain that silver coating everywhere else. And this is really cool, because nothing is really gonna kill your buzz faster than having some nice, awesome, shiny new wheels on that nice, awesome, shiny new Mustang and seeing some rusty braking components peeking out between the two. So what's the whole deal with this slotted and drilled brake technology? Well, without getting into brakes 101, what I can tell you in a nutshell, is that the idea behind this is just to help reduce brake temperatures over a solid or blank rotor. In some cases, up to 180 degrees according to the gang over at Power Stop and ultimately that's just gonna make for a less brake fade and a more consistent pedal when the car or the brakes get pushed a little harder. And aside from the cooling benefits, you're also gonna maintain a cleaner braking surface, thanks to the slots here, helping to remove any excess brake dust, moisture, dirt, things like that, again, just maintaining more of a consistent braking performance. And another really big thing to point out here with Power Stop's kit is that, every single rotor that comes out of the factory is balanced first, so the new owner doesn't have to worry about any excess noise, vibration, shaking or shimmying. I do also want to point out that this kit is going to be for the rears only on your S550 Mustang, whether it's a EcoBoost GT base or performance packed car. This kit does also not include any pads. But guys, if I were you, take my advice, grab a set of pads while you're in there. You're gonna have everything ripped apart, not a bad idea, because ultimately it's only going to increase your braking performance. We do have a few sets available here on the site if you wanna check those out before pulling the trigger on these rotors. But maybe one of the best things about this kit from Power Stop is the price. You're looking at right around 100 bucks for the two rotors here. Power Stop lineup is typically a little bit more affordable in the land of big brakes and this falls right in line with that. Certainly adding in a set of your favorite pads will add to that price slightly, but in the world of big brake upgrades, this one is very affordable. Moving on to the installing, as I said a little earlier, there is a fair amount of work to get these installed along with some elbow grease. But overall, pretty straight forward stuff. Soft two out of three wrenches on the difficulty meter, maybe a couple of hours from start to finish. Now obvious statement of the day here guys, you're gonna have to get the rear of the car up in the air in order to access the brakes, so take those wheels off as well. But do yourself a favor, crack those lugs loose before you get the rear of the car in the air because you really wanna make sure you don't have your parking brake engaged before you start with this install. With the rear wheels removed, you will need to go ahead and remove the rear calipers as well before you can actually remove the rear rotors. In order to do so, you will just need a basic socket set so you can tackle the two bolts securing the calipers to the rear of the car. If you did grab some new pads, now it would be the time to swap those out. With the caliper out of the way, you can now go ahead and remove the factory rotor. Sometimes a rubber mallet or dead blow hammer can be helpful here. You also have to watch out, sometimes Ford will throw on a little clip securing the rotor to the actual hub, so make sure you don't have any of those in place. If you do, needle-nose pliers or something similar will help you get that out of the way. So once that's swapped over, go ahead and reinstall those rear calipers, toss on the back wheels, and your installation is complete. So if you've already upgraded the front brakes in your S550 GT or EcoBoost Mustang and you're looking for an affordable set for the rears to match, well, the Power Stop Evolution kit is a great option and you can grab yours right here at

      Improve Braking Performance. Improve the braking performance of your 2015-2020 S550 Mustang by upgrading to a pair of Power Stop Evolution Cross-Drilled and Slotted Rear Brake Rotors. Cross-Drilled and Slotted Rotors offer dual benefits. The rounded slots are designed to quickly sweep away brake dust, moisture and debris keeping the contact patch of the rotor clean for better pad bite. While the drilled holes will allow your brakes to run up to 180 degrees cooler, when compared to solid face rotors, to reduce brake fade. Power Stop Evolution Brake Rotors are the ideal performance upgrade for S550 owners who want big brake bite without the price.

      Superior Construction. Crafted from the finest G3000 grade cast iron blanks available on the market today, Power Stop Rotors feature precision machined rounded slots and beveled drilled holes. All of Power Stop's Rotors have been mill balanced for a perfect fit and to reduce the chance of any unwanted noise, vibration, and harshness (NVH). Power Stop Evolution Rotors are then complete in a durable silver zinc plated finish to resist rust and corrosion.

      Vented Vane Design. Power Stop Evolution Cross-Drilled and Slotted Rotors feature a traditional straight vane vent design. Vented rotors help expel hot gasses quicker to improve the overall heat dissipation of the rotor which in turn increases your Mustangs braking performance.
