The "dot" on the tire sidewall is...
I am in the midst of needing new tires for one of the cars. I forget... the "dot" on the sidewall of every tire represents what again? It's either the heaviest point or lightest point on the tire. Thus, you need to either line up the dot as close as possible to the valve stem if it's the lightest spot. Or line it up on the opposite side away as possible if it's the heaviest spot. Which is it?

made in India? I really "dot" have an idea what it is. Use google "dot" com to find out. 
Sorry couldnt resist....
edit: OK..... check this out. Depends on manufacturer

My guess is.... if the dot is the heaviest.... you mount the valve directly across it or if its the lightest you mount the valve where the dot is..... Like what you said.

Here is our writeup on it.
Cliffnotes: In the end, the markers have little, if any, relevance when replacement tires are installed.
Usually it's the high spot of force variation, and should be mated to the low spot of a rim. That's IF you took the time to set up all your wheels to be read with a dial indicator and found the low spot of all the wheels before putting the tires on. Manufacturing techniques have become so good that some manufacturers don't even use them anymore. And, tire balancers do such a better job now than they did back when radial tires had more variation in size.
There's many opinions on it, but in general: put the tires on, get a good road-force balance, and enjoy them.

Drifting
One good smoking drift and it won't matter.
And here I thought that you could mark the rim across from the dot and after your track day you could check to see if the tires are slipping on the rims from hard braking...

This might help. Maybe other manufacturers could go different. I could swear I'd heard the red dot goes opposite the valve. Oh well.
