Line Lock with Drum Brakes ?

^^Yabut remember "foot braking" he is using all 4 brakes, line lok, only 2
I think that's the point of this post. OP does not want to use foot breaking and burn up his rear brakes.

Killer6 was noting that when he foot brakes it he can do the burnout so the ability of the fronts to hold the car is not in question.

And yes he is applying 4 brakes but he is only using 2 to hold the car because he is overpowering the rears during the burnout.
