2013 BMW Z4 Front Brake Rotors

Pilenga Brake Discs, 100% Made in Italy. Pilenga Bimetallic brake rotor feature steel discs attached to an aluminum hub, significantly reducing the weight of the disc assembly. The light weight bimetallic disc provides a reduction of inertial forces, increased acceleration, enhanced braking performance and reduced vehicle emissions. The coated brake disc provides a protective water based coating that prevents rust and corrosion, extended disc life and improved visual appearance. Pilenga manufactures OE-quality brake discs that assures maximum performance and enhanced driving comfort, providing the same levels of quality, technology and performance that are found in many of the OEM fitments. With enhanced thermal inertia, Pilenga high carbon discs reduce both vibration and noise. Pilenga’s meticulously controlled production process makes it possible to precisely contrast the chemical composition of the cast iron, maximizing the percentage of carbon in the discs.

Product Features:

• OE-Equivalent and a direct fit replacement
• Excellent braking performance.
• Attractive appearance (strong visual impact combined with alloy wheels)
• Eco-Friendly long lasting corrosion resistance
• High carbon content
• No reduction in friction coefficient with Pilenga coated brake discs

Since 2008 Zimmermann is offering almost 400 Standard and almost 400 Sports Brake Discs in a coated version named Coat Z. The Zimmermann Coat-Z brake disc provides a protective coating that prevents rust and corrosion, extended rotor life and improved visual appearance. To improve the rust protection during storage and usage, Otto Zimmermann GmbH implements this new Coat-Z technology step by step in its production range. Beside the still optimum function of the brake disc, this coating ensures a consistent attractive appearance. Zimmermann brake discs are usually made of cast iron (with flake graphite) of different qualities; they correspond to the material used for the original spare parts. Therefore, the utilization of such materials (referred to as High Carbon by the competition) has always been a matter of course for Otto Zimmermann.

Product Features:

• Coat-Z protective anti-corrosion coating
• No formation of rust at the hub and herewith improved visual appearance
• Immediate functional capability without removal of the coating before mounting
• Excellent deceleration action and no distortion of friction ring at high temperatures
• Substantial weight saving and therefore less unsprung mass
• Floating mounting enables radial expansion of the brake disc under relatively heavy loads, thus preventing shielding and increasing resistance to heat cracks
• Hot spots prevented by optimized design of ventilation channels
• 1:1 exchange of original disc possible
• Not subject to registration: general ABE certification supplied with disc
• No conversion required for brake tuning
