I agree with Sinbad, although he got bumped a little wide at the start of the lap, it was hardly on purpose, but what he done in the last corner was blatantly not a mistake, he would never have made the corner without hitting into the back of the porsche.
Though, we need an onboard view of the porsche to see if he did spin him out, personally it looks to me like he does spin him out because when it looks like he cuts accross him like Sinbad says, it's probarly just because his rear was being pushed into the spin.
Anyhow, was good watching, I enjoyed the impreza v the corvette more though...
