Here are some photos of my line lock / roll control mod. This mod locks the front brakes while the rear brakes are released, allowing you to do a stationary burnout. By using two solenoids (front left and front right) I was able to maintain the anti-lock and vehicle dynamic control in a factory condition for street use. See for a short video.

tHAT'S SO COOL

 

Most awesome. Been a long time since I've even thought about a LineLock. Very cool for the 1320 people among us.
