These rotors shave 21 lbs of 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 B9 S4-S5-SQ5 rotor is already a stout 350mm (13.8") 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.
Stock vs. JHM
-Rotor Weight: Stock = 27.7lbs(each), JHM = 17lbs(each) - 38% LIGHTER, over 10.5 lbs less each
-Rotor Cooling Air-gap: Stock = 16.15mm(.635"), JHM = 18.5mm(.728") - LARGER for better cooling
-Rotor Cooling Center Fin Design: Stock = Straight, JHM = Airfoil - MORE EFFICIENT for better cooling
-Rotor OD: Stock = 350mm(13.8"), JHM = 350mm(13.8") - SAME
-Rotor Thickness: Stock = 34mm(1.34"), JHM = 32mm(1.18")
-Bolt pattern: - SAME (fits like an OEM rotor would)
INCLUDES: 2 - JHM 2-piece Lightweight Front Rotors. (Each rotor weighs 10 lbs less than stock for a total of 20lbs weight savings.) 35% lighter!
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 B9 S4-S5-SQ5. The rings feature 12 attachment points 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. 12 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.
