Line lock is not really even needed...... More of a novelty item! Old school POWER Brake works fine letting off the brake as the tires start to smoke..... Of course this is IF you have enough power to actually get the tires spinning! Lol :D
Actually, for decades, my line-loc has become part of my every day driving,, as much as the gas or brake pedal.. I use it at every lite, no more holding the pedal, I use it starting on hills, I've used it to help "park" in certain situations, ;-)
Line-loc is now being introduced in production cars under different names, "roll-control", and "hill assist" are some examples...
And it saves burning up the rear brake shoes doing "brake stands"..lol
