Don't let the WRX Nazis fool you...
With equal drivers:
Stock for stock, our GT will still beat the WRX in the 1/8th.
And utterly kill it in the 1/4....
As Eric stated, a boost\fuel increase will get them to compete in the 1/8th with their AWD, but it still won't have the HP\power band in the 1/4 to keep up....
I was at the track last year and some guy in a modded WRX asked me if I was ready to get beat.
I said "Sure, but it won't be you who beats me..."
