I had a quick race with an 06 WRX this morning on the freeway, I saw him weaving through cars behind me trying to get next to me. I pretended like I didn't see him and was more interested in drinking my morning coffee, but he starts revving and flooring it and letting off so I decided to give it a go. So I drop into fourth around 75-80 and push it out to about 120. I pulled about 1.5 to 2 cars on him. I thought with the 2.5 I would get smoked.
I've got an 03 WRX w/ 5sp. and AP stage 1. I'm guesing he was stock.
