Overview

The StopTech ST40 Big Brake Kit is a front brake upgrade designed to enhance vehicle performance. Big Brake Kits provide a supercar look and feel by increasing heat capacity with larger rotors and reducing system compliance with stiffer calipers and stainless steel lines. This kit aims to improve stopping distances, brake modulation, pedal feel, and reduce brake fade.
Show original supplier description
The StopTech ST40 Big Brake Kit is engineered to elevate your vehicle's braking performance, offering a significant upgrade over stock systems. The primary goal is to enhance braking power and responsiveness without negatively impacting the crucial front-to-rear brake torque ratios. Key advantages of this StopTech kit include shorter stopping distances, improved brake modulation for better control, a firmer brake pedal, and reduced susceptibility to brake fade, even under demanding conditions. The kit features patented AeroRotors known for superior airflow, leading to better cooling and extended rotor and pad life. This specific kit includes 4-piston ST40 Red calipers, 328x28mm (12.9-inch) 2-piece slotted Aerorotors, adapter brackets, StopTech brake pads, and stainless steel brake hoses. It is designed for the 2004-2008 Acura TSX. Please note that minimum wheel diameter requirements typically range from 17 inches for 328mm rotors up to 19 inches for larger rotor sizes, and confirming wheel fitment is the customer's responsibility. Calipers and rotors can be custom-ordered in various colors and finishes.
