The M5 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 S2000 is a circuit car by temperament, and the cars that end up on this page are rarely standard underneath: WiseFab knuckles and upgraded axles are common. Wheel speed sensing is where a motorsport ABS conversion succeeds or quietly fails on this platform, so the sensing has been developed front and rear across the combinations these cars actually run rather than for one idealised build.\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\u003eWhat’s Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBosch Motorsport M5 ABS control unit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFront and rear wheel speed sensors and machined sensor mounts\u003c\/strong\u003e, developed to suit your combination:\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eStock knuckles with stock axles\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eWiseFab knuckles with stock axles\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eWiseFab knuckles with Driveshaft Shop axles\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eStainless mounting hardware for the supplied components\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\u003eChoosing your configuration\u003c\/h3\u003e\n\u003cp\u003eThe sensor mounting differs between a stock knuckle and a WiseFab one, so the kit is specified to match what is actually on the car. The mounts are handed (left and right are separate parts) and on a stock-knuckle car the same mount serves front and rear on each side. A WiseFab car uses those same mounts at the front, with dedicated rear mounts to suit the WiseFab knuckle.\u003c\/p\u003e\n\u003cp\u003eAxles matter as well, which is why WiseFab cars are covered on both stock and Driveshaft Shop axles rather than one or the other.\u003c\/p\u003e\n\u003cp\u003eIf you’re not certain what your car is running, send us photos of the front and rear knuckles and axles before ordering and we’ll confirm the right configuration.\u003c\/p\u003e\n\n\u003ch3\u003eHydraulic unit mounting\u003c\/h3\u003e\n\u003cp\u003eOne thing to know up front: there is no 909 hydraulic unit mounting solution for the S2000.

The mounting differs between stock and WiseFab knuckles, so it does need to match. If you’re unsure, send us photos of the front and rear knuckles and axles and we’ll confirm before you order.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does the kit include hydraulic unit mounting?\u003c\/strong\u003e\u003cbr\u003e\nA: No, and we’d rather say so plainly. Everything else is here, the M5 and the developed front and rear sensing for your configuration, but the hydraulic unit location is chosen and made at install, with our guidance. See the section above.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: My factory ABS has never caused a problem. 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: My car is on a different hub or axle combination. Can you help?\u003c\/strong\u003e\u003cbr\u003e\nA: Get in touch and tell us exactly what’s fitted. The three combinations above are what we have developed and tested; anything else is a conversation, not a guess.\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: Yes, more so than our full integration kits, because the hydraulic unit mounting is designed at install alongside the brake lines. Professional installation is strongly recommended. We can install and commission the system in our Newcastle workshop, or supply the kit with our guidance behind your own builder.
