Product Line Details: StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line is designed to provide enhanced braking performance for street and light track use. The combination of cross-drilled holes and precision slots helps to evacuate heat, brake dust, and gases generated during braking. This design reduces the risk of brake fade and maintains consistent pedal feel. The vented rotor construction further improves cooling efficiency, making these rotors suitable for Chrysler and Dodge vehicles requiring reliable stopping power under demanding conditions.

Technical Specifications and Features

These rotors have a nominal thickness of 1.260 inches (32.000 mm) and a discard thickness of 1.181 inches (30.000 mm), ensuring a long service life before replacement is necessary. The rotor’s outside diameter measures 14.173 inches (360.000 mm), with an overall height of 2.295 inches (58.300 mm). The hat section features a coated finish to protect against corrosion, and the rotor mounts using a floating disc design to allow for slight movement, reducing stress and improving braking consistency. The five lug holes have a diameter of 0.657 inches (16.700 mm) and are arranged on a 4.528-inch (115.000 mm) bolt circle diameter, compatible with the specified Chrysler and Dodge models.

Common Applications and Problem Solving

• Improves brake cooling to reduce fade during aggressive driving
• Helps prevent brake pad glazing and uneven wear
• Reduces brake dust accumulation on wheels
• Enhances stopping power for Chrysler 300, Dodge Challenger, Charger, and Magnum
• Addresses rotor warping issues caused by heat buildup

Installation Notes and Tips

• Ensure rotor thickness is within discard limits before installation
• Use proper torque specifications for lug nuts to avoid rotor distortion
• Inspect brake pads and calipers for wear or damage during rotor replacement
• Clean rotor surface with brake cleaner before installation to remove any protective coatings
• Check compatibility with ABS systems as these rotors do not include an ABS tone ring
