CLEARANCE ITEM: Brand new lightweight front brake kit that is offered at a special CLOSE OUT clearance price. We have a limited number of in stock kits.

The BimmerWorld View: StopTech C43 brake kits are focused on club racing sprint, medium endurance, and dedicated track cars that need a race-level braking package but are also weight sensitive and don't want the negative side effects from too-large brakes. The trend in brake kits has been "bigger is better" and that's just not the case all the time. Sometimes bigger brakes just add more weight without any appreciable gains in performance. The larger kits also suffer pad knockback and force you into a larger tire/wheel for clearance. It's time to re-focus braking performance on what counts!

StopTech C43 Race for E36 318i/323is/325i/328i and E46 323i/325i/328i features -

  • Super-focused on light weight and performance
  • 50% lighter than ST40 caliper
  • Patented Aerorotors with directional cooling vanes
  • Smaller diameter rotor for lower weight and MOI with less pad knockback
  • Super-thick rotor does not give up any cooling capacity
  • Fits under 17" wheels
  • Race kit: Race pads, bi-directional slot pattern, no anti-rattle hardware

The C43 caliper is a 4-piston layout, forged from aluminum, sized and machined to minimize weight. The C43 is 50% lighter than a ST40 caliper and even lighter than the Trophy kit! Stainless steel piston noses and anti-knockback springs are optional. A single bridge bolt saves weight and reduces pad change times. C43 calipers do not include dust boots so street use should be minimized. Pads are 17mm or 20mm thick and the shape is shared with AP and Wilwood calipers (Hawk HB521, Pagid 8195 or 2205, and PFC 7751). Note: caliper photos may not be updated to reflect the latest coating. StopTech is transitioning from grey hardcoat to Nickel plating.

Rotors are 2-piece 309x32mm with a slot pattern. The diameter is kept small to reduce MOI (Moment of Inertia) and prevent the pad knockback so pervasive in oversized Big Brake Kits. The 32mm thickness contains more than enough cooling capacity for these cars. The rotors feature StopTech's patented Aerorotor directional vaning pattern that expels hot air to keep the rotor cool and your braking performance on point. Aerorotors are specifically designed to circulate cooling air and cool the brakes faster. This leads to more consistent braking performance, less heat soak throughout the system, and longer pad life. Race CBK kits do not come with anti-rattle hardware but do have a floating system that further reduces pad knockback.

StopTech's C43 caliper is the result of years of R&D in road racing and short-track circle racing, which is a merciless proving ground for brakes. With R&D input and testing from BimmerWorld, StopTech has made this caliper design available for limited BMW applications through BimmerWorld. BMW C43 kits feature all of the great advantages of a regular StopTech Big Brake Kit: the Balanced Brake Upgrade(R) approach that optimizes brake distribution to improve traction at all four corners, patented rotor cooling vanes for longer pad life and less fade, and the stiffest caliper designs in the industry.

C43 calipers do not use dust boots on the caliper pistons and are only sold for racing or exclusive track activity only. Caliper dust boots play a key role in preventing debris from damaging the inner piston seals and causing a very dangerous loss in brake pressure. As with any racing braking system, periodic rebuilds and regular fluid changes using an appropriate fluid are strongly advised.

C43 calipers are only available in dark-grey military-spec hardcoat.

CBK kit comes with StopTech pads. Hawk pads (HB521), Pagid (2205 or 8195), and PFC pads (7751) are also available. Replacement rotor rings are also available.
