Two things. wrx-no-mo, what mods do you have done to your rex? my gf just got one and wants to start modding it. next thing: whoever thinks a stock 2-v 99+ Mustang isn't good for 13's should have been there when a i ran a 13.8 bone stock in my bullitt. and if you think a bullitt has that much hp over a regular GT you're wrong.
