if your STI isnt modded, be careful.
I have a buddy with a new one with mods and it will do 0-60 in about 5 seconds. They also make a twin turbo kit for them that makes unbelievable power. Granted they weigh somewhere near 8000 lbs, but they can be fast if modded. if it is stock, i wouldnt worry about it, but if they put a box on it and a few other things, it makes a world of difference in some of those trucks.
I will call him to see what he runs in the 8th or quarter mile.
you could always do a 0-100-0 run. it may be easy for him to hit 100, but 8000lbs doesnt stop very quickly.
