FAQs

What is the minimum thickness for these discs?

The minimum thickness for these discs is 10 mm. They should be replaced if they reach this limit.

Do these discs come with brake pads?

No, this product is for a pair of brake discs only. Brake pads should be purchased separately.

How do I remove the oil coating?

Use a dedicated automotive brake parts cleaner and a clean, lint-free cloth to wipe the disc surfaces until all oil residue is gone.

Are these discs ventilated?

No, these are solid discs with a thickness of 12 mm.

What is the bolt pattern for these discs?

These discs are designed with a 4-hole bolt pattern.

Can I use these on the rear axle?

These are designed specifically as front brake discs. Check your vehicle's specifications to confirm if your vehicle utilizes 246.7 mm discs on the front.

Troubleshooting

Braking feels spongy or inconsistent immediately after install

Ensure the braking system is properly bled and all protective oil was thoroughly cleaned from the disc surfaces.

Vibration felt through the steering wheel while braking

Check that the hub surface was cleaned of all corrosion before mounting the disc and verify that the lug nuts were torqued in a star pattern.

Pros and Cons

Pros

  • High-quality construction from a reputable automotive brand
  • Meets strict ECE-R90 safety compliance standards
  • Oiled finish effectively prevents pre-installation corrosion
  • Precise dimensions ensure straightforward installation

Cons

  • Solid disc design is not suitable for high-heat performance or track use
  • Requires professional cleaning to remove protective oil before installation
  • Compatibility limited to 4-bolt hub assemblies

Setup, Compatibility & Care

Before installing these discs, use a brake cleaner to thoroughly remove the protective oil coating from the surfaces. Failure to do so will result in poor initial braking performance and potential glazing of the new pads. Ensure that the wheel hub mating surface is clean and free of rust or debris, as any unevenness can lead to lateral runout and pedal vibration. Always consult your vehicle's service manual for the correct torque specifications for your caliper bracket and wheel bolts. Regular inspection of the disc thickness is recommended, and the discs must be replaced if they wear down to the 10 mm minimum thickness threshold.
