Rear Brakes for footbrake.. Disc or Drums?

The ironic part is 99.9% of the people out there have discs in the front, drums in the rear and do burnouts with line lock. (front brakes only)

So tell me again how rear discs affect the ability to hold the car in one place?

Most people do burn outs with wet tires. At the starting line I try to foot brake stall as high a rpm as I can. Most I can do is 28-3000 at the line.
