Dynamite Friction 7004-31052 Disc Brake Rotor Set - Front and Rear

Drilled and Slotted Brake Rotor Set

Dynamite Friction DFC Rotors-Drilled and Slotted-Silver, part number 7004-31052, is a front and rear disc brake rotor set for select BMW applications. It is built for drivers who want OE-style fitment with a performance-oriented rotor design for 1985-1989 BMW 635CSi, 1985-1988 BMW 535i, and 1988 BMW 535is.

The drilled and slotted surface is engineered to improve pad bite, clear debris, and reduce heat buildup during braking. The silver GEOSPEC coating helps protect the rotor surface while the cast iron construction is machined to tight tolerances for stable, consistent braking.

Key Features

• Part number 7004-31052
• Drilled holes help reduce heat buildup on the rotor face
• Slots clear brake dust and road debris and help reduce pad glazing
• Non-directional finish supports faster, more even brake pad bed-in
• GEOSPEC coated rotor surface for added corrosion resistance
• Machined to OE specifications for durability, reliability, and stability
• 100% inspected for balance and critical dimensions

Product Details

DFC Premium Performance Brake Rotors use G3000/G11H18 cast iron and are processed through precision machining and electronic mill-balancing before final inspection. The result is a rotor set built to meet OE-level dimensional requirements while adding the braking characteristics of a drilled and slotted design. For BMW 635CSi, BMW 535i, and BMW 535is owners, 7004-31052 provides a direct-fit rotor solution for front and rear positions.

What This Rotor Set Helps Address

• Excess rotor heat during repeated braking
• Brake pad glazing from trapped debris and heat
• Reduced initial pad bite in wet conditions
• Uneven pad bedding after rotor replacement
• Brake vibration concerns related to rotor balance and machining variation

Installation Notes and Tips

Verify vehicle year, model, and axle position before installation. Clean the hub mounting surface thoroughly and inspect pads, calipers, and hardware condition before replacing rotors. Follow proper brake bedding procedures after installation to help achieve smooth, quiet braking performance.

Quality Assurance

Each rotor is inspected for balance and critical attributes after machining to confirm OE specification compliance. DFC backs this rotor set with a 12 month or 12,000 mile limited warranty against defects in material and workmanship.
