I run this kit on my Black Series (my car in vids), this is an awesome kit and a great feature, this is the only way to get a proper burn-out and it will save your rear rotors and pads from the tortures of a non-line lock burn-out. This is a must have mod for anyone that EVER goes to the drag strip with their car.
