Looks like it lost weight to me.
I'm not trying to argue, either. I don't argue, I discuss, learn and inform.
Also, even if the WRX can "beat" the STI in a straight line, the WRX lags behind on extended track days compared to the STI. Getting a WRX just to drag race it is missing the point anyways, so not sure why that was brought up.
