    JHMotosports is proud to offer a complete performance based braking solution for the B9 S4! Our JHM Lightweight Rotors have been proven over the many years of testing to be a cost-effective performance based solution to expensive OEM rotors.
    The full front and rear package equates to an astonishing 32LBS of rotational weight savings!




    JHMotorsport Front 2-piece Lightweight Rotors Specs:

    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)

    The front rotors shave 21 lbs of unsprung weight from the front of your car while increasing braking performance, plus they bolt on just like stock!
    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!

    Very nice. Do you guys have any recommendations for the pads? I see EBC is discouraged in the product page.

    Yes! We would recommend the Hawk HP 5.0 Pads: Front - HB865B.620 / Rears - HB866B.652. We have not added them to the store yet (that's coming this week) but we would be happy to assist with getting you a set if you are ready!

    Can I ask what the advantage is with going to a thinner rotor than stock?

    Yes, could you please explain why I would want to with a thinner rotor? Seems like they would get heat soaked a LOT faster but they wouldn't last very long (wear)
