Yeah, right. You're not looking to hoon about doing burnouts, just wanting to responsibly clean off those tires for a good data run. Suuuure. And if it happens in a Dunkin donuts parking lot in front of a bunch of onlookers, well, no accounting for coincidence. If you want to really crush in the drags you will go back to AWD and put on a set of drag radials, perhaps with some rubber conditioner to soften them up a bit (I hear there are also some common household chemicals that will make for a nice smokey 'tire cleaning').

The answer to your Q is called a torque converter, kind of a hydraulic clutch; keep exploring this new world of burnouts and you'll learn a lot more about these than you ever wanted to (you're on target with that 'snap and seize' part). It lets the $15000 motor spin wildly while the $9000 drivetrain sits there held in place; then you engage it suddenly and hope that it is the tire contact patches that give up and create a burnout. Trans brakes just do the holding in the tranny, instead of with the brakes - what you crave is a line lock (and a '70's Camaro).
