Drastically increase the braking performance on the 2016-2020 Shelby GT350 or GT350R with these PowerStop Z26 rear brake pads. The carbon-ceramic compound used in the PowerStop Z26 Street Warrior ceramic brake pads is intended to increase stopping power while reducing brake dust and noise. PowerStop reinforces the compound using a low-dust ceramic formula infused with carbon fiber for ultimate fade resistance and offers extraordinary stopping power under the toughest conditions. Z26 pads retain constant wear and performance while ensuring a quick break-in thanks to OE-positive mold technology and a thermally scorched pad surface. Chamfered edges help optimize cooling and suppress noise, while additional noise dampening is performed by the dual-layer rubberized shims. Stainless-steel hardware and hi-temp brake lubricant is included with the brake pads making it easier to complete your brake job.

Brake pad break-in procedure:
Perform 5 moderate to aggressive stops from 40 mph down to 10 mph in rapid succession without letting the brakes cool and do not come to a complete stop. If you’re forced to stop, either shift into neutral or give room in front so you can allow the vehicle to roll slightly while waiting for the light. The rotors will be very hot and holding down the brake pedal will allow the pad to create an imprint on the rotor. This is where the judder can originate from.
Then do 5 moderate stops from 35 mph to 5 mph in rapid succession without letting the brakes cool. You should expect to smell some resin as the brakes get hot.
After this is complete, drive around for as long as possible without excessively heating the brakes and without coming to a complete stop (Try for about 5 minutes at moderate speed).
This is the cooling stage. It allows the heated resin in the brake pads to cool and cure.
After the brakes have cooled to standard operating temperature, you may use the brakes normally.
Bedding in your brake pads and rotors is an essential task that is required for proper braking performance and longevity. Follow along with the article below, and we will walk you through these how-to steps. more
PowerStop set out to design a kit that removed the guesswork from shopping online for brakes by including everything in one box—pads, rotors, hardware and more. LMR offers PowerStop upgrade kits available for 1987-current Mustangs and Lightnings! Every brake pad uses a carbon-fiber ceramic material, providing a dust-free, noise-free, fail-free braking experience. Engineers work to ensure everything made is a direct bolt-on replacement for the original brakes, making it easy to upgrade your Mustang or Lightning braking performance! PowerStop has been providing a safe, problem-free performance brake upgrade since ’95 and is equally committed to eco friendly practices.

Wheel Diameter
The wheel size is the diameter of the wheel, in inches, not counting the tire.
Modern tires in North America have several other measurements associated with their size.
A tire designated as a "225/70R14" denotes a tire with the following dimensions: width of tread: 225 mm; ratio of tire height to width: 70 percent; rim diameter: 14".
Therefore a 185/70R14 has the same rim diameter and aspect ratio, but a smaller overall diameter and narrower tread face than the 225/70R14.
Wheel Width
Wheel Backspacing
The easiest way to measure backspace is to lay the wheel face down onto the ground so the backside of the wheel is facing up.
Take a straight edge and lay it diagonally across the inboard flange of the wheel. Take a tape measure and measure the distance from where the straight edge contacts the inboard flange to the hub mounting pad of the wheel. This measurement is the backspace.
The photo below shows three wheels with 2", 3", & 4" backspace.
Wheel Bolt Pattern
The bolt pattern or bolt circle is the diameter of an imaginary circle formed by the centers of the wheel lugs. Bolt patterns can be 4, 5, 6, or 8 lug holes. A bolt circle of 4x100 would indicate a 4 lug pattern on a circle with a diameter of 100mm.
The diagram indicates the proper measuring methods. 6 lug wheels are measured like the 4 lug wheels.
Wheel Offset
The offset, measured in millimeters, can be negative or positive, and is the distance from the hub-mounting surface to the rim's true centerline. A positive offset means the hub-mounting surface is closer to the outside edge of the wheel; a negative offset means the hub-mounting surface is closer to the inside edge of the wheel. Offset affects the scrub radius of the steering and it is advisable to stay within the limits allowed by the vehicle manufacturer. If tires are fitted which are significantly wider than those specified by the manufacturer, a compromise may have to be adopted whereby a wheel with less offset is used to prevent the tire rubbing on the suspension.
Wheel Centerbore
The centerbore of the wheel is the opening in the middle of the wheel, surrounded by the lug holes. This opening helps to center the wheel to the hub. Its diameter is typically measured in millimeters (mm) and varies in size depending on vehicle application. Manufacturers approve up to a 1% variance in tolerance to pass wheels during inspection.
