Detailed Product Description

This StopTech Sport Cross-Drilled & Slotted Disc Brake Rotor (127.44184L) is designed specifically for select Lexus vehicles, including the GS and IS series as well as the RC models. The rotor features a vented design with curved vanes that promote efficient airflow to reduce heat buildup during braking. The cross-drilled and slotted surface helps to evacuate gases, dust, and water, improving braking consistency and pad bite under various driving conditions.

The rotor’s coated hat finish offers enhanced corrosion resistance, extending the service life of the part. With a nominal thickness of 30.000 mm and a discard thickness of 27.000 mm, this rotor meets strict specifications for safe and effective braking. The floating disc mounting system allows for slight movement between the rotor and hub, reducing the risk of warping and improving overall brake system durability.

Applications and Problem Solving

• Reduces brake fade caused by excessive heat during spirited driving or towing
• Improves braking performance in wet or dusty conditions by clearing debris from the rotor surface
• Minimizes rotor warping and vibration through vented design and floating mounting
• Protects against corrosion with a coated hat finish, extending rotor lifespan
• Ensures proper fitment and compatibility with Lexus GS300, GS350, GS450h, IS200t, IS300, IS350, RC200t, RC300, and RC350 models

Installation Notes and Tips

• Verify rotor thickness before installation; replace if below discard thickness of 27.000 mm
• Ensure proper torque on mounting bolts to maintain floating rotor alignment
• Inspect brake pads and hardware for wear and replace as necessary during rotor installation
• Clean rotor surface with brake cleaner to remove any protective coatings before use
• Check wheel lug pattern compatibility: 5 lug holes with 114.3 mm bolt circle diameter
