  • Rotors: The kit features larger, slotted rotors that improve airflow and reduce brake temperatures.
  • Brake Pads: High-performance pads are included, designed to provide optimal grip and minimal fade.
  • Mounting Hardware: All necessary hardware for installation is included, ensuring a straightforward swap.

Installation Process

Installing the StopTech ST-60 Big Brake Kit on your IS-F can be done at home with the right tools and a little mechanical knowledge. Here’s a step-by-step guide:

Tools Required

  • Jack and jack stands
  • Socket set
  • Torque wrench
  • Brake cleaner
  • Brake fluid
  • Flathead and Phillips screwdrivers

Step-by-Step Instructions

  • Prepare the Vehicle: Park the IS-F on a flat surface, engage the parking brake, and loosen the lug nuts on the front wheels.
  • Lift the Vehicle: Use a jack to lift the front of the car and secure it with jack stands.
  • Remove the Wheels: Take off the front wheels to access the brake components.
  • Remove Stock Calipers: Unbolt the stock calipers and carefully detach them from the rotor. Set them aside.
  • Remove Stock Rotors: Unbolt and remove the stock rotors from the hub.
  • Install New Rotors: Position the new StopTech rotors onto the hub and secure them with the provided hardware.
  • Install New Calipers: Attach the new ST-60 calipers to the rotor, ensuring they are aligned correctly and bolted securely.
  • Install Brake Pads: Insert the high-performance brake pads into the calipers.
  • Reattach Wheels: Put the wheels back on and hand-tighten the lug nuts.
  • Lower the Vehicle: Carefully lower the car back to the ground and then torque the lug nuts to the manufacturer’s specifications.
  • Bleed the Brakes: Use the brake fluid to bleed the new system, ensuring there are no air bubbles.
  • Test the Brakes: Before driving, pump the brakes to ensure proper pressure and feel.

Performance Testing

Once the StopTech ST-60 Big Brake Kit is installed, it’s essential to test the performance. Here are some methods to evaluate the upgrade:

  • Short Stops: Perform several short stops from 30 mph to assess immediate braking response.
  • Hard Stops: Test hard braking from higher speeds to evaluate fade resistance and stopping distance.
  • Track Testing: If possible, take the IS-F to a track to evaluate braking performance under more demanding conditions.

Conclusion

Upgrading to the StopTech ST-60 Big Brake Kit is a worthwhile investment for any Lexus IS-F owner looking to improve braking performance. With enhanced stopping power, reduced fade, and better pedal feel, this kit transforms the driving experience.
