Driving home a couple hours ago I pull up behind a Black/Orange GT3 RS. It looked awesome and sounded great as the driver heel toe downshifted to the light. Traffic was clear down in the mexico coast so I was curious to see if he wanted to play, he did!
He punched it while he was still infront of me, I was reeling him in slowly, he then slowed down. Now neck to neck, at around 50mph we go at it and I pull him immediately, I have a car in my lane up ahead so I had to go around him while still on it, at this point the GT3 is about 0.5-1.25 car lenghts behind me, it was hard to tell honestly...I glance down at the hud and let off after I see I'm crusing at a healthy 136
No thumbs up or anything from the other driver, I don't think he was too happy or expected these results, a plain old stock M6 giving him a run for his money

He turned off into his gated community shortly after we were done racing.
Very exhilarating, made my day
I also remember some discussion on 6speed about a GT3 (non RS) being faster then the M5/M6 stock. Mmmhmm
He did have a passenger but I'm a big guy weighing in at 235, they looked small

I only have charcoal filters pulled out. I love my beast
Here's a picture of the victim.
