StopTech specializes in high-performance braking components, including Big Brake Kits. They focus on vehicle-specific engineering, taking into account factors like hydraulic systems, weight transfer, and tire contact for optimal braking torque distribution.

Kit Types:
* Standard Big Brake Kits: These typically feature 2, 4, or 6-piston calipers, designed for specific BMW chassis. Calipers are known for their rigidity, minimizing flex and noise. Aerorotors (patented, internally-vaned) are available in slotted or cross-drilled, with an optional zinc coating for corrosion resistance. Standard kits come with Sport pads and model-specific stainless steel brake lines and hardcoat anodized 6061-T6 billet aluminum brackets.
* Trophy Kits: These are lighter, track-oriented kits with lightweight calipers and rotors, and a dark grey hard-anodized finish. Trophy Sport kits are suitable for street use (including dust seals and anti-rattle hardware), while Trophy Race kits are strictly for track use (lacking dust seals and potentially noisier). Rotor sizes typically range from 332-380mm.
* C43 CBK Kits: These kits aim to provide Big Brake Kit performance in a more compact and lighter package, featuring 309x32mm rotors and lighter C43 4-piston calipers. C43 kits are primarily for track use (no dust seals). C43 Sport kits include anti-rattle hardware. They can fit under smaller wheel sizes (17" and even some 16").
