The M5 system provides ultra-fast processing, highly accurate wheel slip control, and configurable ABS strategies for track use. Eleven selectable calibrations on a 12-position map switch allow the ABS behaviour to be tuned for tyres, surface conditions, and driving style.\u003c\/p\u003e\n\u003cp\u003eThe Exige is already a circuit car with numberplates, so the conversion is held to that standard: the hydraulic unit goes in the standard location, the factory wheel hard lines and wheel speed sensors stay, and the cabin hardware is bracketed into the console and dash rather than hung off them. The yaw sensor mount is designed for the parcel shelf with provision for a VBOX recorder, because on this car the data logger was always going to be fitted anyway.\u003c\/p\u003e\n\n\u003ch3\u003eThe problem with factory ABS in competition: what track drivers call “ice mode”\u003c\/h3\u003e\n\u003cp\u003eABS works by holding each tyre near a target slip ratio, the difference between wheel speed and vehicle speed, where 0% is a freely rolling tyre and 100% is a locked one. Peak braking force sits somewhere between the two, and exactly where depends on the tyre and the surface. The cycling you feel through the pedal is the system chasing its target, and while it’s in slip control, pressing harder adds nothing; extra pedal force won’t be sent to a tyre the system already considers at its limit.\u003c\/p\u003e\n\u003cp\u003eRoad-car calibrations have to be built conservatively: one calibration must stay safe on every surface a road car can meet, down to the very worst. Under genuine circuit braking (real speed, semis or slicks, kerbs and bumps working the tyre) that conservative logic can settle on a slip target far below the grip actually available. The result is what drivers call ice mode: the system refuses to build brake pressure no matter how hard you stand on the pedal, and the only way out is to come almost completely off the brake, let the wheels match the car’s speed, and reapply. If you braked at the limit for the corner, that margin doesn’t exist.\u003c\/p\u003e\n\u003cp\u003eIt isn’t a fault, and pads, fluid or bigger discs won’t touch it. It’s a road calibration operating outside the envelope it was designed for.\u003c\/p\u003e\n\u003cp\u003eMotorsport ABS approaches the problem from the other direction: the driver selects the calibration for the tyre and conditions actually in use, and the system controls to a slip target appropriate for genuine circuit grip. Eleven selectable calibrations on the 12-position map switch cover the range from wet circuit to slicks, chosen before the braking zone, not discovered during it.\u003c\/p\u003e\n\n\u003ch3\u003eBrake balance: what the factory system quietly manages for you\u003c\/h3\u003e\n\u003cp\u003eOn a platform like this the ABS\/ESP doesn’t just prevent lock-ups; it actively manages front-to-rear brake distribution. Under light braking the system can run more rear brake than the hydraulics alone would give, keeping the car flat; under hard braking it bleeds rear pressure down as weight transfers forward. The distribution your car actually runs is electronic, not mechanical.\u003c\/p\u003e\n\u003cp\u003eThat has two consequences for a competition build. Unplugging the ABS doesn’t return the car to some honest pre-electronic state; it removes the brakeforce distribution the base hardware was designed around, and can leave the car with a hard pedal and a rear balance never intended to stand on its own. And altering mechanical bias underneath a stock system means fighting a computer that’s redistributing pressure on top of your changes.\u003c\/p\u003e\n\u003cp\u003eA motorsport ABS conversion makes brake balance deliberate again: the overall front-to-rear balance is set properly in hardware, which is why this kit includes a bias valve mounting solution beside the master cylinder, and the M5 then controls slip at each wheel from that correct baseline, rather than papering over an incorrect one.\u003c\/p\u003e\n\n\u003ch3\u003eWhat’s Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBosch Motorsport M5 ABS control unit\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eHydraulic unit mounting in the standard location\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFactory wheel hard lines retained\u003c\/strong\u003e: only the master-cylinder pipes need to be made\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFactory wheel speed sensors retained\u003c\/strong\u003e: harness connectors supplied, trimmed and terminated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eABS harness re-orientated\u003c\/strong\u003e to suit the standard hydraulic unit location\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eBias valve mounting beside the master cylinder\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eMap switch and MIL bracket in the centre console\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eDiagnostic port and main switch bracket, LHS dash\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFactory ABS ECU cover retained\u003c\/strong\u003e, preserving the steering angle communications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eYaw sensor mount for the parcel shelf\u003c\/strong\u003e: available with or without VBOX recorder provision\u003c\/li\u003e\n\u003cli\u003eMounting hardware throughout\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eBrake lines from the master cylinder to the hydraulic unit are made to suit the vehicle at install: 909 specifications call for Goodridge or Speedflow hardware.\u003c\/em\u003e\u003c\/p\u003e\n\n\u003ch3\u003eWhat you give up: factory torque vectoring\u003c\/h3\u003e\n\u003cp\u003eThe factory torque vectoring function is delivered by the standard ESP system, and it cannot be retained once that system is replaced.

Why replace it?\u003c\/strong\u003e\u003cbr\u003e\nA: Because the problem shows up at circuit pace under maximum braking, which is precisely when you can’t afford it. A road calibration has to stay safe on every surface a road car might meet, so at real speed on semis or slicks it can settle on a slip target well below the grip you actually have, and refuse to build pressure no matter how hard you push the pedal.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Why not just unplug the ABS instead?\u003c\/strong\u003e\u003cbr\u003e\nA: On this platform that also deletes the electronic brake distribution the car was designed around, leaving a rear balance that was never meant to stand on its own. A motorsport system with properly set mechanical balance is the engineered path, not the workaround.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What does the VBOX provision actually do?\u003c\/strong\u003e\u003cbr\u003e\nA: The parcel shelf yaw sensor mount is offered in two forms: one that carries the yaw sensor alone, and one that also locates a VBOX recorder. If the logger is going in the car anyway, having both mounted properly from the same bracket beats finding somewhere for it later.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Do I need special tools or skills to install the kit?\u003c\/strong\u003e\u003cbr\u003e\nA: Some expertise is required, and brake lines from the master cylinder to the hydraulic unit are made to suit at install.
