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

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line is designed to enhance braking performance through improved rotor cooling and pad bite. The cross-drilled holes and precision slots help evacuate gases, dust, and water from the rotor surface, reducing brake fade and maintaining consistent pedal feel. This product line is ideal for drivers seeking a balance between everyday drivability and enhanced braking response on compatible Chrysler and Mercedes-Benz vehicles.

Technical Specifications and Features

This rotor features a solid disc design with a coated hat finish to protect against rust and corrosion. The nominal thickness of 0.354 inches (9.000 mm) ensures durability and longevity, while the discard thickness of 0.287 inches (7.300 mm) indicates the minimum safe thickness for replacement. The rotor measures 10.945 inches (278.000 mm) in outside diameter and 2.205 inches (56.000 mm) in overall height, fitting precisely on vehicles with a 5-lug bolt pattern and a 4.409 inch (112.000 mm) bolt circle diameter. The center hole diameter is 2.638 inches (67.000 mm), and the rotor weighs approximately 9 lbs (4.090 kgs).

Applications and Problem Solving

• Compatible with Chrysler 300CE, 300E, 300TD, 300TE and Mercedes-Benz C230, C240, C280, Crossfire, E300, E320, SLK230, SLK280, SLK300, SLK320 models
• Reduces brake fade during extended braking by improving heat dissipation
• Minimizes brake dust buildup and water retention on rotor surface
• Helps maintain consistent brake pedal feel under varied driving conditions
• Prevents premature rotor warping and extends brake component life

Installation Notes and Tips

Ensure the rotor is installed on vehicles matching the specified fitment to maintain proper brake system function. Verify the rotor thickness before installation and replace if below discard thickness. Use proper torque specifications for the 5-lug mounting pattern with a 4.409 inch bolt circle diameter. The coated hat finish requires no additional corrosion protection but inspect for damage during installation. ABS tone ring is not included, so confirm compatibility with your vehicle’s ABS system.
