Yeah I don't know about 115mph. I would say that most of it was limited by traffic on the road. More like 80-85 with a few fast sprints while passing so we could try to stay together. Still very fun though, on the other hand, I was towards the back so I wouldn't couldn't say how fast the lead dogs were going, but I didn't see anything too crazy until we got into the hills. My stock springs and struts got too much roll on them to keep up in the twisties. Those guys can really haul. Guess that will be the next upgrade.
