Detailed Product Description

This Dynamite Friction rotor is part of the DFC Geoperformance Rotor - Drilled and Slotted line, which focuses on delivering rotors with enhanced surface technology for improved brake pad contact and heat management. The vented design allows air to flow through the rotor, reducing heat buildup during aggressive braking. The directional slotted and drilled surface helps evacuate gases, dust, and water, maintaining consistent braking performance under various driving conditions.

The rotor’s nominal thickness of 30 mm ensures durability, while the discard thickness of 28.4 mm indicates when replacement is necessary to maintain safety and performance. The rust resistant coating and Geospec silver grey hat finish provide additional protection against corrosion, which is especially beneficial for vehicles exposed to moisture and road salt.

Compatible Vehicles and Applications

• Designed specifically for BMW 335d, 335i, 335is, 335i xDrive, 335xi, and X1 models
• Ideal for drivers seeking improved braking response and rotor longevity
• Suitable for both daily driving and spirited driving conditions
• Addresses issues such as brake fade, rotor warping, and uneven pad wear

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (28.4 mm) before installation
• Clean rotor surface and hub mounting area to prevent runout
• Torque lug nuts to manufacturer specifications for proper fitment
• Check compatibility with existing brake pads and calipers on BMW 335i and X1 models

Quality Assurance and Warranty

Dynamite Friction manufactures the 830-31082L rotor to meet OEM standards for fit, form, and function.
