SKU: JHM-NH-365X34



**NOTE: As of 8/1/2012, all JHM Lightweight Rotors will now feature zinc plating!!!** This high quality coating will slow the effects of corrosion on the rotor surface and will keep your rotors looking good through the winter!

In stock and ready to ship.


Shaves 8lbs 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 replacing your complete rotor with OEM parts when your aluminum hat is reusable. You save between $300 and $450 with our kit! We also do away with the annoying crack prone holes and sell these either totally plain or with slots (use drop down box below)

ONLY AVAILABLE SLOTTED: Our slotting is quiet and not noticeable.

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 B7 RS4.

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
