Interesting, but the conclusions probably boil down to common sense. The first link doesn't reference the distinction that being front or rear wheel drive might bring to the appropriate conclusion. The second link does distinguish between front and rear wheel drive but along fairly predictable lines.

Front wheel drive cars are generally biased towards understeer in handling while rear wheel drive bias is towards oversteer. Assuming the other pair aren't shiny threaded garbage then it seems logical to put you best threads on the end that defines the bias in the handling.
