TCXMZ5402 TRACTION CONCEPTS Vlsd Kit MX5 Mazda Miata Roadster

Review TRACTION CONCEPTS Mazda 1.8 Nb And Concept Vlsd Kit for MAZDA MIATA ROADSTER MX5

The Traction Concepts TCXMZ5402 is a high-performance VLSD (Variable Length Slotted Drill) kit designed specifically for the Mazda Miata 1.8 NB/MX-5 (2001-2005) roadster. This performance upgrade is an excellent choice for those seeking improved traction, stability, and braking performance.

The TCXMZ5402 kit comes with eight (8) slotted drilled and vented brake rotors, each featuring a unique, angular drilling pattern. This pattern not only enhances the aesthetic appeal of your Miata's wheels but also helps to dissipate heat more effectively. The drilled design allows for better cooling and increased bite, ensuring consistent braking performance even during the most demanding driving conditions.

Each rotor in this kit is made using Traction Concepts' proprietary QFS (Quenched Ferrous Silicon) metal casting process. This process results in a high-density, high-carbon cast iron rotor that offers superior strength and durability. The QFS rotors also feature a chamfered edge, which helps to reduce noise and vibration.

The TCXMZ5402 kit includes four (4) slotted drilled and vented front brake pads and four (4) slotted drilled rear brake pads. These pads are manufactured using a high-friction compound, ensuring superior stopping power and longer pad life. The slotted design of the pads allows for effective gas and debris evacuation, further enhancing the braking performance.

The kit also includes stainless steel brake lines, which offer better resistance to corrosion and flex than traditional rubber lines. These lines help maintain consistent brake pressure, ensuring consistent braking performance and improved pedal feel.

Installing the TCXMZ5402 kit is a relatively straightforward process, thanks to the included installation hardware and step-by-step instructions. The kit is designed to work seamlessly with your Miata's existing brake system, allowing you to enjoy the benefits of improved braking performance without the need for additional modifications.

In summary, the Traction Concepts TCXMZ5402 VLSD kit is an excellent upgrade for Mazda Miata 1.8 NB/MX-5 (2001-2005) roadster owners seeking improved traction, stability, and braking performance. With its high-performance rotors, vented pads, and stainless steel brake lines, this kit delivers superior stopping power, consistent performance, and enhanced aesthetics.
