Also in development: Bosch ABS M5 for the Toyota 86 and Subaru BRZ. Hit the pedal hard at the start of the braking zone on a car with real grip and the factory calibration can settle on a slip target far below what the tyre is actually giving, commonly known as ice mode.
The pedal goes hard and stops responding, standing on it adds nothing, and the only way out is to get off the brake and reapply: margin you don't have if you braked at the limit. Pads and technique move the threshold; they don't change the calibration. The M5's calibrations are built for genuine circuit grip; you select the one that matches the tyre and conditions you're actually running.
And the install being developed for this platform needs nothing made: no fabrication, no brake lines to bend or flare. Every part of the system bolts straight to the car, and detailed fitting instructions come in the box.
Development is running on the first generation cars, and a second generation GR86 and BRZ page is now open for registered interest while we assess what carries over. Swipe: the M5 unit installed in our first generation development car.

In development: a full Bosch ABS M5 kit for the Ford Sierra Cosworth, worked up on our own cars, a Mk1 and a Mk2. Forty years on, the factory Teves takes some working around. The master cylinder generates front brake pressure only; the rears are applied by dynamic pressure fed straight from the pump and accumulator, lose boost and you're braking on the front axle alone, unassisted. And on the RHD cars the MC and pump sit on the right of the bay, with the ABS valve block mounted remotely on the chassis rail under the inlet manifold. Our kit re-establishes the whole system with current hardware: bolt-in, no holes drilled, fully reversible. It will be a comprehensive kit: all mounting brackets, compatible active wheel speed sensors and their mountings, a master cylinder and booster solution, the loom and ECU integration, all able to be adapted per project. And if your Cosworth is left hand drive, register your interest; we're happy to work with LHD owners. Link in bio.

Wheel speed sensing at the wheel, not the driveshaft. Measure inboard and everything between the sensor and the tyre ends up in the measurement: the driveshaft winds up under braking load like the torsion spring it is, spline and diff lash get driven back and forth as the ABS cycles pressure, and the sensor gap moves with all of it. Wheel speed sensing needs that gap held inside a narrow band — vary it enough and the signal drops out, or returns a speed the system can't reconcile with the other three wheels. A motorsport ABS doesn't guess at that point: it declares a sensor fault, lights the lamp and takes itself offline, usually in the hardest braking of the day. Back in the paddock every sensor tests fine on a rolling wheel, because nothing is broken — the measuring point just moves. Our kits relocate the tone ring and sensor outboard: past the compliance, past the lash, gap fixed for the life of the car. Why some factories measured inboard anyway — and why that logic doesn't carry over to a modern four-channel system — is in the full write-up, link in bio.

The MM7.10 inertial sensor — standard in every ABS M5 kit. Six axes of vehicle motion: longitudinal, lateral and vertical acceleration, plus yaw, roll and pitch rates — all broadcast on CAN, for the logger or for an ECU running its own vehicle-dynamics functions. On the logging side they earn their keep quickly: roll rate reads what the platform actually did through a setup change, vertical acceleration catches kerb strikes and surface, and pitch rate covers the braking phase — how the car takes its nose-down set when you first hit the pedal, and how cleanly it recovers as you release into the corner, laid over brake pressure in the same log.

Everything in a 909 R32 GT-R ABS kit, before it goes in the car. Bosch ABS M5 hydraulic unit, MM7.10 inertial sensor, four DF11 wheel-speed sensors, front and rear pressure sensors, 12-position map switch, mounting hardware and the loom to tie it together. Eleven selectable calibrations on the switch, changed from the cabin — wet circuit through to slicks. The pressure sensors give the system its front and rear brake pressure picture, and your logger gets the same channels. Rear wheel speed sensing relocates outboard — tone rings and machined hub mounts are in the kit — and the hydraulic unit mounts to suit your chosen location, with four in-car positions developed so far. Nothing in the kit is a universal bracket; it's all specified for the car it's going into. Swipe: the outboard rear tone ring on the car, the front sensor mount installed, and the map switch live on the dash — ABS map on the DDU. Kit details on the site — link in bio.
