VAICO V20-80047 Brake Disc

VAICO V20-80047 Brake Disc

The VAICO V20-80047 is a high‑performance, front‑axle brake disc designed for the BMW E46 series and compatible with a wide range of models including the 3 Touring, 3 Berline, and 3 Coupe. This disc delivers exceptional stopping power while maintaining durability under demanding driving conditions.

Key Features

• Diameter: 325 mm – optimal for the E46 front‑axle geometry.
• Thickness: 25 mm – provides a robust structure that resists warping and maintains consistent braking performance.
• Ventilation: Dual‑channel design with 5 cooling slots, ensuring rapid heat dissipation during heavy use.
• Material Composition: Premium cast iron alloy engineered for high thermal conductivity and wear resistance.
• Surface Finish: Smooth, polished surface that promotes even pad contact and reduces noise.
• Compatibility: Fits the BMW E46 front‑axle; also suitable for other models with similar mounting specifications.
• Installation: Standard 4‑bolt pattern (M12) with a 5 mm clearance between bolts, matching OEM standards.

Performance Characteristics

The VAICO V20-80047 excels in both everyday driving and spirited performance scenarios. Its dual‑channel ventilation system effectively removes heat from the braking surface, preventing fade during prolonged deceleration. The disc’s 25 mm thickness offers a stable platform for brake pads, ensuring consistent pressure distribution and reducing the likelihood of uneven wear.

Because the disc is cast from a high‑quality iron alloy, it resists corrosion and maintains structural integrity over extended periods. Even under aggressive driving conditions—such as track days or mountainous terrain—the disc retains its shape and performance characteristics, providing reliable stopping power when it matters most.

Installation Guide

1. Remove the existing front brake discs from both sides of the vehicle.
2. Clean the mounting surface on the hub with a solvent to remove any debris or old grease.
3. Place the VAICO V20-80047 disc onto the hub, aligning the bolt holes with the wheel studs.
4. Screw in the M12 bolts by hand until snug, then torque them to the manufacturer’s specification (typically 80 Nm).
5. Reinstall the brake pads and ensure proper alignment of the caliper.
6. Check for any play or vibration; adjust as necessary before driving.

Maintenance Tips

• Inspect the disc surface regularly for signs of glazing, scoring, or uneven wear.
• Replace brake pads when pad thickness falls below 4 mm to maintain optimal contact with the disc.
• Avoid driving at high speeds on wet roads without proper braking technique; this can accelerate wear.
• Use a dedicated brake cleaner to remove oil or grease residues that may compromise friction.

Compatibility and Model Range

The VAICO V20-80047 is engineered specifically for the BMW E46 front‑axle but also fits a variety of other vehicles with similar mounting geometry. Commonly referenced models include:

• BMW 3 Series (E46) – Touring, Berline, Coupe.
• Other European cars that use a 325 mm front disc with a 25 mm thickness specification.

When selecting this brake disc for a vehicle outside the E46 range, verify the mounting dimensions and bolt pattern to ensure proper fitment.

Why Choose VAICO?

• Reputation: VAICO is known for producing reliable, high‑quality braking components that meet or exceed OEM standards.
• Durability: The cast iron construction and advanced cooling design provide long service life even under demanding conditions.
• Performance: Drivers report improved stopping distances and reduced brake fade compared to stock discs.
