It was my understanding that they were electronic limited to 157, but mine only does 154. Radar detector GPS speed said ~155. With the 10 Speed and 3.55's, I was at like 6800rpm in 7th so I didn't have much more speed left anyway.
I generally never leave it in automatic shifting. I don't really use Sport+ or any of the other modes, just Sport and then the paddles. I find the automatic shifts to be imprecise and never what I'm looking for.
No chips, scratches, or broken bits. Has about 500 miles on it, comes with the nuts for it. Local pickup in the Daytona area is preferred but I'll ship at buyers expense.
