Description

The StopTech ST40 Big Brake Kit is engineered to deliver significant braking improvements for your vehicle, offering a supercar aesthetic and enhanced performance. This front big brake kit achieves superior stopping power by utilizing larger rotors for increased heat capacity and employing stiffer calipers and stainless steel lines to minimize system compliance. The design prioritizes balanced brake upgrades to maintain optimal front-to-rear torque ratios, thereby maximizing tire traction and preventing performance compromises often associated with other brake upgrades. This kit includes a set of 4-piston ST40 calipers, 328x28mm 2-piece slotted Aerorotors, adapter brackets, StopTech brake pads, and stainless steel brake hoses. The Aerorotors are designed with patented airflow technology for improved cooling, reduced fade, and extended rotor and pad life. The calipers themselves are constructed for maximum stiffness, featuring a patented bridge design that enhances clamping force during hard braking and minimizes pad taper for more consistent performance. Minimum wheel diameters are required for proper fitment: a 17-inch wheel is needed for the 328mm rotor. It is the customer's responsibility to verify wheel fitment. StopTech offers custom options for caliper colors, including Silver, Black, Yellow, and Blue, as well as a cross-drilled rotor pattern. These custom options can be specified during checkout.
