This kit simplifies EMS installation when using traction control, by allowing a "bolt on" addition of wheel speed sensors which aftermarket EMS systems can correctly read. Compare at $300-$400 per sensor for Motec/Pi Wheel Speed Sensors, and that doesn't even include mounting brackets!
Kit includes (4) CNC machined brackets, 4 sensors, 4 new connectors w/pins, and new ARP wheel bearing hardware.
Kit is direct bolt on for 2001-2010 ABS equipped cars. OEM Tone wheels will need to be added to the non-ABS cars for correct functionality.
