Description BMW 5 Series (E60) Front Competition Brake Kit Paragon Track Performance Big Brake Kits offer superior braking performance specifically designed for track day enthusiasts. Come complete with every component required to upgrade your brake system. Developed with performance, quality, and longevity in mind, only the finest materials/components were used to ensure the brake kits to perform and last under both street and track conditions. Features Paragon PA015 / PA035 6 piston calipers *Only difference between the PA015 and PA035 calipers is the maximum rotor size they can accommodate Fully-floating 2-piece rotors, with directional ventilation vanes for optimal cooling performance. Runs up to 30% cooler than O.E. rotors Hard anodized or ENP nickel plated calipers, and hard anodized rotor hats for increased resistance to wear and discoloration under extreme track conditions Piston sizes optimized for each application. Designed to work flawlessly with OEM ABS and brake master cylinder. Compatible with OEM rear brakes Confidence-inspiring heat resistance during extended sessions. Optimum bite, modulation characteristics, thermal stability, and durability Includes: One pair of Paragon PA015 / PA035 6 piston calipers One pair of Paragon fully-floating 2-piece rotor assemblies with hard anodized 6061-T6 aerospace grade aluminum hats, stainless steel bobbins, and anti-rattle clips One set of Paragon P3 “Street/Track” semi-metallic brake pads (manufactured by Winmax Japan, other compounds available at additional cost) One pair of caliper mounting brackets and all necessary hardware One pair of Goodridge DOT approved stainless steel braided brake lines One set of caliper anti rattle clips Detailed installation manual ***Please verify wheel fitment / clearance before ordering. All Paragon big brake kits are custom made/packaged to order, and cannot be returned due to wheel fitment issues. Wheel Fitment Template Download (PDF): 355x32mm / 378x36mm > How to use the wheel fitment template (PDF) **355mm brake kits generally require 18′′ or larger wheels, while 378mm brake kits generally require 18′′/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) Front Kit Number: PBK.02.086.355.320.TL.01.02.Px.F (355x32mm Rotor) PBK.05.086.378.360.TL.01.02.Px.F (378x36mm Rotor) PA015 / PA035 6 Piston Calipers Mil-Spec hard coat anodized or ENP electroless nickel plated finish 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 Staggered piston bore sizes for improved brake balance and even pad wear 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/nickel plated for improved wear resistance. Will not deteriorate under extreme heat like painted/powder coated calipers Replaceable stainless steel abutment plates to allow smooth braking action and prevent wear on the caliper body Strong, yet lightweight. Each caliper weighs 6.5 lbs (without pads) Optional anti-knockback springs Stainless steel bleed screws and crossover pipes Each caliper is pressure tested to guarantee proper operation ENP caliper finish Extremely durable and resistant to heat, wear, and corrosion More scratch resistant vs. hard anodized finish Easy wipe off of brake dust, brake fluid stain, and grime due to the low porosity of the plating Visually stunning finish which never deteriorates. Blends perfectly with any vehicle’s color scheme 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 72 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.
