Complete matched systems — caliper, disc, pad and bracket — engineered for direct fitment. 4 to 10-piston configurations for the leading European performance marques.
Product Line 02 — ECR Racing
A complete brake system upgrade in one box. Every ECR Racing big brake kit is a matched assembly — we engineer the caliper, disc, pad compound and bracket together so every component is optimised for the application. No mixing and matching, no adapters.
Configurations
We don't fit one caliper to every car. Each ECR Racing big brake kit is specified around the vehicle's weight, power output and intended use — road, track day or competition.
Road and light track use. Significant upgrade over OEM for fast road and occasional track days.
330–355mm disc
The most popular configuration. Suited to regular track use and high-performance road cars.
355–380mm disc
Track-focused. For heavier performance cars and drivers who use the brakes hard, repeatedly.
380–410mm disc
Maximum performance. Competition-grade clamping force for the highest-demand applications.
410–440mm disc
In the box
Every ECR Racing big brake kit is a complete system. Bolt it on and drive.
Matched multi-piston caliper in the correct specification for your vehicle. Supplied ready to fit — no machining, no modification.
ECR Racing 2-piece disc assembly — high-carbon iron ring on 7075-T6 aluminium bell. Sized and ventilated for the specific application.
Matched pad compound selected for the caliper and disc combination. Road, road/track or full track compounds available.
Vehicle-specific mounting bracket and all installation hardware. Direct fit — no adapters, no drilling, no welding.
