Product Details

The EBC GD1421 GD Sport rotor features wide directional slots designed to improve brake performance under demanding conditions. These slots help dissipate heat and gases while maintaining consistent pad contact, reducing brake fade during spirited driving or heavy braking situations.

Key Features:

  • Wide slot design enhances cooling and reduces operating temperatures
  • Manufactured from OE-spec grey cast iron for reliable performance and longevity
  • Directional slot pattern helps expel gases and debris from the braking surface
  • Direct replacement for worn factory rotors
  • British-made construction (most applications) with rigorous quality control testing

EBC GD Sport rotors are designed as an upgrade from standard replacement rotors, offering improved thermal management for drivers who demand more from their braking system. Each rotor undergoes precision testing for runout, hardness, and material composition to ensure consistent quality and proper fitment.

Was cheaper than any other place I could find on the parts I needed. Online store is set up very well, and when I called to confirm stock, I was pleasantly surprised to speak with someone quickly who I could actually understand and converse with. I will be doing a lot of business in the future with Autoplicity.com. Thanks a lot!

Best Price I could find, fast shipping. I shall return!

Lowest prices around the web and excellent customer service. The only real issue was the wait between placing the order and when it was shipped. Took 4 days but I chalk that up to the large amount of business they due to their prices being so competitive. For the lowest prices that I've seen I didn't mind waiting a bit longer!

Very fast shipping and product was secure in package to avoid damage....will be ordering from autoplicity again for sure. Also the price could not be beat.

Superb company! Autoplicity had the lowest price, shipped it quickly, and it was exactly as advertised - couldn't ask for better results!

Best price online for the programmer I ordered. Fast and reasonable shipping costs.
