I noticed the whole wrx with bolt ons vs 370z with bolt ons whos faster argument. Let me clear this up for everyone. In the 1/4 mile, the wrx hands down.
A friend of mine has a pro tuned stage 2 2009 wrx making 300 awhp and 330 awtq. I have catback exhaust and k & n filters at the moment.
From a dig, i have no chance really.
From a roll on, about 70 mph, a near stock 370z IS faster, and we have done many runs, on closed tracks and airport runways of course. from 70 mph to 140 mph my near stock 370z pulls a good 2-3 cars on a protuned 300 awhp 2009 wrx.
From a 45 mph roll on, the wrx gets the jump, i catch it by 110 mph.
Anyways, i've driven both, and owned an evo x, the wrx is an awesome car, and definetly better suited for the northern climate than a 370z, a better buy for this area if you dont want to own 2 cars. Nice buy OP, have fun drifting around in the snow!
