This article applies to the Lexus IS (2005-2013).

Modifying the brakes on your Lexus IS will improve performance and improve the look of your vehicle. It is important to have the correct tools and patience to perform these modifications. If you are ready to take your Lexus to the next level, this is a great way to do so. Remember, the stronger your engine is, the better your brakes should be.

Pads

Skill Level - Moderate, brake pad replacement is not difficult, but making the proper adjustments can sometimes be tricky.

Replacing your brake pads is one of the easiest way to improve the overall performance of your vehicle. The Hawk HPS or high performance street level brake pads will help you with this task. The Hawk brake pads will improve your stopping ratio by 20 to 40 percent over the Lexus IS OEM brake pads, and will also reduce noise. There are many different brands on the market that will custom fit your Lexus IS and offer similar performance upgrades. Most high performance brake pads on the market will have a lifetime guarantee against manufacturer's defects.

Replacing your brake lines will improve the performance of your Lexus IS, and also increase the longevity of the braking system.

Rotors and Calipers (Full Kit)

DIY Cost - $400

Professional Cost - $1,000

Skill Level - Moderate to Difficult, there is precision necessary in fitting the new brake system.

The performance goal with the brake modification should be to improve the stopping distance of your vehicle in the shortest amount of time. While keeping the torque ratios in line with the specifications, you should also look to improve the heat capacity of the brake. By installing new rotors that have air flow capacity and new calipers that offer better clamping, quicker stops, and less wear on your pad system, you will be improving the overall efficiency of your braking system. Also, you will be increasing the lifespan of your vehicle.

The second performance consideration is safety. The brake modification upgrades will generally provide a safer brake system, which is more efficient for your vehicle. However, it is important to note that the new brake system may increase the overall torque of your vehicle. It is imperative that you ensure the front brake torque does not overpower the rear brake torque as detailed in the specifications. It is also important to confirm that the tires on your vehicle are capable of handling the new brake system, as well as your brake lines and accessory parts.

The wide variety of color options available for both rotors and calipers can greatly enhance the exterior appearance of your vehicle. Most of the rotor options available—and most popular—are metallic in nature with silver and gold. Depending on your taste and the overall look you are attempting to achieve, you may also choose from a variety of rotor sizes. As previously mentioned, proper rotor venting will greatly improve your braking system performance.

Brake calipers also come in a wide variety of colors and sizes. Depending on the specification for your braking system, you can choose from almost any standard color to install on your Lexus IS.

Brake modification or replacement is an excellent way to improve the performance and look of your vehicle, but be sure to balance those goals with the specifications and parts of your Lexus IS.
