FAQs
Are these discs sold as a pair?
Yes, this product includes two brake discs for the front axle.
What is the minimum thickness for these rotors?
The minimum thickness allowed before replacement is 28.5 mm.
Will these fit any Audi vehicle?
No, compatibility is specific to models like the A4 (B8), A5, A6, A7, and Q5 (8RB) as well as the Porsche Macan. Always verify your specific part number compatibility.
Does the coating need to be removed before use?
No, the protective coating is designed to be worn off naturally by the brake pads during the initial bedding-in process.
Can I install these myself?
While technically a bolt-on part, brake system installation involves critical safety components; professional installation is highly recommended.
Troubleshooting
Brake judder or vibration during stopping
Check for uneven installation surfaces or debris behind the rotor hat; ensure the wheel bolts are torqued evenly.
Accelerated pad wear
Inspect caliper sliders for sticking and ensure the brake pads are compatible with high-performance rotors.
Pros and Cons
Pros
High-carbon construction improves durability and thermal management
Coated finish provides superior protection against rust and environmental wear
Includes necessary mounting hardware for direct replacement
Optimized for 17-inch rim clearance on a wide range of premium vehicles
Cons
Requires professional installation to ensure proper bedding and rotor runout
Minimum thickness threshold of 28.5 mm must be strictly monitored for safety
Specific compatibility restricted to 17-inch brake size configurations
Setup, Compatibility & Care
Before installation, verify that the vehicle is equipped with 17-inch rims, as the 345 mm disc size will not clear smaller wheel assemblies. Ensure all hub surfaces are cleaned of rust and debris before seating the new rotors. It is recommended to use a torque wrench to tighten the provided mounting screws to factory specifications. To maximize the lifespan of the 09.B970.1X discs, avoid aggressive "panic" stops during the first 200 miles of driving to properly bed the pads to the new disc surface. Always inspect the discs during tire rotations and replace them immediately if the thickness drops below the 28.5 mm threshold.
