**355mm brake kits generally require 18" or larger wheels, while 380mm brake kits generally require 19" or larger wheels. Fitment varies due to different specs / wheel design. Verify fitment with wheel fitment template.

Application:

• 2003-2010 BMW 5 Series (E60) Rear

Kit Number:

• PBK.04.086.355.320.TL.01.02.Px.R (355x32mm Rotor)

• PBK.04.086.380.320.TL.01.02.Px.R (380x32mm Rotor)

PA025 4 Piston Calipers

• CNC machined from billet 6061-T6 aluminum

• Outstanding rigidity. Reduces compliance which allow for a consistent pedal feel, and improves responsiveness/modulation characteristics

• Titanium nitride (TiN) coated pistons. Improve durability and extend service intervals by protecting the sliding surfaces of the pistons. Allow smooth piston travel

• Stainless steel pistons can act as an effective thermal barrier due to the lower thermal conductivity vs. aluminum pistons, which help prevent brake fluid boiling and brake fade. Extra machining is done to minimize contact with the pads

• High temperature piston seals and internal dust seals are utilized to withstand the heat generated under harsh track conditions and extend caliper service life. Internal dust seals are able to offer protection against debris/contaminants and will not melt as easily as the external dust boots that are commonly used on OEM calipers

• Hard anodized finish for improved wear resistance. Unlike painted/powder coated calipers, hard anodized finish will not deteriorate under extreme heat

• Replaceable stainless steel abutment plates to allow smooth braking action and prevent wear on the caliper body

• Strong, yet lightweight. Each caliper weighs 5.5 lbs (without pads)

• Optional anti-knockback springs

• Stainless steel bleed screws and crossover pipes

• Each caliper is pressure tested to guarantee proper operation

Floating 2-piece Rotors

• Floating 2-piece design allows thermal expansion of the rotor while minimizing deformation and ensuring the rotor is self-centered with the pads

• Superior braking and cooling performance

• Features 48 directional ventilation vanes to create suction, turbulence, and guides cool air through the rotor for improved heat dissipation and increased resistance to cracking

• Made of CM-250 special formulated high carbon alloy cast iron. Allows for an optimal bite, thermal characteristics, high-temperature strength, and durability

• Heat treated to release stress in the rotor to avoid deformation and vibration

• State-of-the-art CBN surface machining to ensure better break-in with new brake pads

• Excellent thermal capacity. Allows the rotors to absorb and dissipate heat more efficiently and help reduce chance of brake fade

• Replacement rotor rings available at competitive price

Curved Directional Ventilation Vanes

Features 48 directional ventilation vanes to create suction and turbulence, and guide cool air through the rotor to achieve better heat dissipation and increased resistance to cracking under harsh track conditions. Each rotor is left or right side specific, and the ventilation vanes are optimized to spin in a particular direction to pump the maximum amount of cool air through the rotor. This design allows the rotor to run up to 30% cooler than O.E. rotors and increases cooling efficiency by up to 30% over standard 1-piece units. Brake fade and judder are minimized during extended sessions. This means the brake system can withstand heavier track usage and provide consistent braking performance lap after lap.

Slotted Friction Face

Slotted rotor face pattern improves brake consistency by constantly cleaning the contact surface and dissipate heat generated, and gases released when the pads come into contact with the rotors. Slotted rotors have a superior advantage over blank rotors in wet or raining conditions by preventing water films to form between the brake pad and rotor surface.

Hard Anodized Aluminum Hats

• CNC machined from lightweight 6061-T6 aerospace grade aluminum

• Unsprung weight reduction

• High strength and durability

• Type III Mil-spec hard anodized to increase resistance to wear, corrosion, and discoloration

Floating Bobbins & Mounting System

Utilizes T-Bobbin rotor to hat mounting system to allow "float" in both radial and axial directions, and minimize brake judder. The high quality stainless steel hardware are corrosion resistant which allows secure mounting, and smooth expansion and contraction throughout heat cycles. Anti wear clips (McLaren spring clips) are utilized to slightly pre-load the rotor assembly and minimize rattling noise.

Caliper Mounting Brackets

CNC machined caliper mounting brackets to ensure superior strength, durability, and secure mounting of calipers to knuckles.

Paragon Brake Pads
