The Foundation of a True 2-Piece Rotor: TTSPORT Forged Aluminum Hats

A two-piece rotor is only as good as its foundation. Our forged aluminum rotor hats (or "bells") are the critical link between your brake rotor and your vehicle's hub. Engineered for maximum strength and minimum weight, these hats are essential for reducing unsprung mass, managing heat, and ensuring the precision alignment required for high-performance braking.

Whether you're replacing a worn component or building a fully custom big brake kit, these hats provide the rigidity and thermal stability needed to prevent brake judder, extend bearing life, and deliver a consistent, confident pedal feel under the most demanding conditions.

Core Engineering Features

  • High-Strength 6061-T6 Aluminum: Machined from aerospace-grade forged aluminum, providing an exceptional strength-to-weight ratio that significantly reduces unsprung and rotational mass for sharper handling and suspension response.
  • Superior Thermal Management: Aluminum's high thermal conductivity rapidly draws heat away from the rotor and hub, reducing the risk of heat soak, bearing damage, and brake fade during aggressive use.
  • Precision CNC-Machining: Engineered with sub-millimeter tolerances to ensure perfect concentricity and alignment between the rotor, hat, and hub, eliminating a primary cause of vibration and uneven pad wear.
  • Hard-Anodized Finish: A durable, military-spec hard-anodized coating provides superior resistance to corrosion, oxidation, and abrasion from road debris and brake dust, ensuring long-term durability and appearance.

Frequently Asked Questions

What are the main benefits of a 2-piece rotor over a 1-piece?

There are two primary advantages: a significant reduction in unsprung weight due to the aluminum hat, which improves handling, and superior heat dissipation. The aluminum hat acts as a heat sink, pulling heat away from the iron rotor and hub, which drastically reduces brake fade and the risk of warping.

Are these hats "floating" or "fixed"?

Our rotor hats are designed to be compatible with both fully floating and fixed hardware systems, depending on the specific application and rotor type. Please specify your requirements when ordering to ensure you receive the correct configuration for your setup.

Can I use these hats with another brand's brake rotors?

Our hats are engineered to the exact specifications of TTSPORT brake rings. While they may be dimensionally compatible with other rotors, we cannot guarantee proper fitment, alignment, or safety when paired with non-TTSPORT components. For guaranteed performance, we strongly recommend using a complete TTSPORT rotor and hat assembly.

The Finishing Touches: Ordering Brake Accessories

The big parts get all the glory, but the right accessories are what separate a good brake setup from a great one. Here’s how we help you get the exact supporting parts you need, from high-performance fluid to custom brackets.

  1. Tell Us What You're Working With.

    Give us the rundown on your vehicle (make, model, year, VIN) and your current brake setup. Knowing your caliper and rotor specs, plus how you drive, helps us nail the fitment.

  2. We'll Pinpoint the Right Parts.

    Our team will recommend the perfect accessories for your system—whether you need stainless steel brake lines for a firmer pedal, high-temp brake fluid for the track, or custom-machined caliper brackets and rotor hats for a bespoke build.

  3. You Confirm the Details & Order.

    We'll present you with the options. You review the recommendations, finalize your choices, and complete the order easily through our website or a custom invoice.

  4. We Assemble Your Kit.

    Once you give us the go-ahead, we gather all the correct components, double-check compatibility, and assemble your tailored accessory package.

  5. We Inspect, Pack, and Ship.

    Everything gets a final quality check before being securely packed. As soon as it's on its way, we'll send you the tracking info so you can follow it to your door.
