Product Details

The Brembo 4K3.9013A PISTA 4 TY3 is a high-performance 2-piece rear brake disc system designed for track and competition use. This premium rotor features a 380mm outer diameter, 28mm thickness, and utilizes Brembo's advanced 2-piece floating design that separates the friction ring from the aluminum bell for superior heat management and reduced unsprung weight.

Key Specifications:

  • Rotor Diameter: 380mm (14.96 inches)
  • Rotor Thickness: 28mm (1.10 inches)
  • Bell Offset: 54mm (Type A configuration)
  • 2-piece floating disc construction with aluminum hat
  • Designed for rear axle application
  • PISTA 4 TY3 specification for racing applications

Key Features:

  • Lightweight 2-piece design reduces rotational mass for improved handling and acceleration
  • Floating disc design allows for thermal expansion and reduces heat transfer to the wheel bearing
  • High-carbon cast iron friction ring delivers consistent bite and fade resistance
  • Precision-machined aluminum center bell for optimal weight savings
  • Track-focused PISTA specification engineered for extreme thermal cycling
  • Type A bell configuration ensures proper caliper alignment and fitment

Brembo PISTA series rotors are engineered for serious motorsports applications where performance, consistency, and weight reduction are critical. The 2-piece construction provides the thermal management needed for extended track sessions while maintaining the structural integrity required for competition use.

Very pleased with the purchase and dealing with you / will continue on shopping with y'all

fast support through Chat. Excellent prices.

I ordered a tire from thmotorsports that the manufacturer had discontinued two years earlier and which I could not find anywhere else, without checking customer reviews first, something I never do. Had I checked reviews first I would never have placed the order as the reviews I read after placing my order were uniformly awful. But rather than call and cancel the order, which was my first impulse, I resisted the urge to do so and waited. A day later, the shipping update said my tire had shipped, so I waited. Another day later, the shipping update said my tire would arrive a day later by the end of the day so I waited. On the appointed day, the tire, exactly the tire I had ordered and which was unavailable anywhere else, arrived at the end of the day, brand new, in perfect condition and I was utterly amazed. Thank you, thmotorsports, I am so glad I did not look at your reviews before placing my order.

The part I needed was in stock at a fair price and delivery was free. Item delivered in perfect condition in a few days.

Great price and fast shipping. I will order from them again

Very nice and easy
