Front Rotors (pair) 380mm BBK, JHM 2-piece Lightweight for B8-RS5

The Original Audi Lightweight Rotors engineered and manufactured in the USA since 2010!

 

Due to popular demand, all of our 2-piece, lightweight rotors will now come with black anodized rotor hats featuring Type 3, hard anodizing, the highest quality and hardest anodizing available for aluminum. This will make the rotor hats more resistant to fade and wear and will hide brake dust better. Due to popular, demand all lightweight rotor rings will also feature zinc plating. This high quality coating will slow the effects of corrosion and keep your rotor rings looking good through the winters.

IN STOCK AND READY TO SHIP!

 

Saving unsprung weight from the front of your car while increasing braking performance, plus they bolt on just like stock! This is great alternative to a full on Big Brake Kit since the stock B8 RS5 is a stout 365mm (14.4") and most may not want to spend $2,000 plus for a full Big Brake Kit. We basically brought the same high performance great cooling designed rotor to these drop in (fit like stock) front rotors and at a 1/4 of the price or less of a full Big Brake Kit.

 

Fitment:
-Direct Replacement for OEM #4B3 615 301E for the Left Front & 4B3 615 302A for the Right Front
-C5 RS6, All

 

Stock vs. JHM
-Rotor Weight: Stock = 23.5lbs(each), JHM = 22.5lbs(each) - BIGGER AND LIGHTER, 1bs less each
-Rotor Cooling Air-gap: Stock = 13mm(.512"), JHM = 18.5mm(.728") - LARGER for better cooling
-Rotor Cooling Center Fin Design: Stock = Straight Fin, JHM = Airfoil - MORE EFFICIENT for better cooling
-Rotor OD: Stock = 365mm(14.4"), JHM = 380mm(15") - 4% LARGER for better caliper leverage on the wheel
-Rotor Thickness: Stock = 34mm(1.34"), JHM = 34mm(.1.34") - SAME
-Bolt pattern: - SAME (fits like an OEM rotor would)

 

INCLUDES: 2 - JHM 2-piece Lightweight Front Rotors. (Each rotor weighs 6.5lbs less than stock for a total of 13lbs weight savings.) 24% lighter!

 

SLOTTED ONLY: We can build plain rotors but this would be special order and take 2 to 4 weeks for the same price.

 

Outer ring specs:
We worked closely with a race brake manufacturer that supplies many NASCAR racers and a couple major brake kit companies. Due to their expertise we chose to have them build us the outer rings to our specs to fit the C5 RS6. 10 attachment points with 3/8 inch zinc plated bolts for durability and strength.

 

Center hat specs:
We CNC machine the Aluminum center hats in house based on their recommended materials and thicknesses for durability. 10 attachment points for durability and strength. We also engrave JHM in them in 3 locations equal from each other, it looks clean and doesn't jump out or look tacky.

 

NOTE: We also have RS6 rear rotors available. Please see this section for more information.

 

Please note: JH Motorsports does not recommend using EBC brake pads with our 2-piece lightweight rotors. Customer have reported and we have found EBC pads leave excessive pad deposits that can cause brake pulsation. Many EBC pads have a break in coating that reacts with the zinc plating used on our rotors
