Product Details

The Zimmermann 150.3422.70 Formula Z is a high-performance two-piece brake rotor engineered for demanding driving applications and spirited performance. This advanced design features a cross-drilled friction ring made from specially alloyed grey cast iron paired with a lightweight aluminum alloy hub, connected by steel floating pins to create a composite brake disc that delivers superior braking performance under extreme conditions.

Key Features:

  • Two-piece floating design with aluminum hub and cast iron friction ring connected by steel pins
  • Cross-drilled ventilated rotor for enhanced heat dissipation and debris removal
  • 345mm outer diameter x 28mm thickness with 52.5mm height
  • Minimum thickness: 26.4mm for safe operation throughout service life
  • Coat Z corrosion protection coating for lasting appearance and extended rotor life
  • High carbon content friction ring for optimal braking performance
  • 5-bolt mounting pattern with 120mm bolt circle and 79mm centering diameter
  • Directional design for front right installation
  • Weight: 8.66 kg (19.1 lbs) - significantly lighter than solid one-piece rotors

Performance Benefits:

  • Reduced unsprung mass improves vehicle handling and driving dynamics
  • Floating bearing design allows friction ring to expand radially at high temperatures
  • Minimizes thermal deformation and significantly reduces risk of heat cracks
  • Prevents heat transfer to wheel hub, ensuring stability under extreme loads
  • Optimized ventilation channels prevent hot spots and maintain consistent braking
  • Excellent deceleration properties even at elevated temperatures

The Zimmermann Formula Z was specifically developed for high-performance and heavy vehicles requiring superior braking performance. The floating pin connection allows the friction ring to expand independently when heated, preventing cracks and maintaining disc shape under maximum stress. This German-engineered brake rotor replaces OEM part number 34112282446 and is ideal for performance-oriented drivers who demand reliability and consistent braking power.

Note: Sold individually. Professional installation recommended. Follow proper break-in procedures for optimal performance and longevity.

Good, so far!

Order delivered on time

I purchased a Walker tailpipe (resonator) assembly for a Toyota Sienna. Autoplicity offered the part at the best price and I found the website easy to use. The part arrived within the timeframe I expected. However, the part was shipped without any protective wrapping whatsoever, which resulted in substantial malformation of both ends of the pipe. While a professional shop may have a pall of some kind for quickly re-rounding the pipe, I am a DIYer, and it took me 15 minutes to get things back in working condition. Whether shipped from Autoplicity or directly from Walker, a part like this should have at least had some bubble wrap taped around the ends of the pipe to prevent such damage.

easy shopping

Very easy

Best price I found for a long tube header and catless mid kit. Kit arrived within a week as described. Will be shopping with autoplicity again.
