Achieve the perfect burnout every time with the Vader Solutions Line Lock Kit, designed to give you total control over your front brakes at the push of a button. Whether you’re heating up your tires for the drag strip or showing off at a meet, this system ensures smooth, consistent launches and effortless tire warm-ups without factory ECU intervention.
BMW’s safety systems often cut power when both the brake and throttle are pressed simultaneously — but with this line lock kit, that limitation is gone. Once activated, the solenoids hold your front brakes independently, allowing full throttle control while keeping your rear tires spinning freely. The result? Cleaner burnouts, faster 60-foot times, and total confidence at the line.
Professional installation is strongly recommended. The kit should be wired through an aftermarket switch (aerospace-style recommended) for proper operation and safety.
