I'm not really trying to start anything here, I thought I made that clear...

Upon the invite, I found a tire difference calculator and it shows a speedometer and odometer difference of -.62, as noted by NorCalCoug. At 160mph, that's only 1 mph, but the speedo isn't exactly perfect in the upper limits either, so I've read and heard. It also effectively changes the final drive from 4.11 to 4.08. Of course you don't have a 4.11, but you get the idea. I forgot to take into account a splitter and your final drive change, but I still don't believe you could reach an "actual" 160 mph on any given day. I'll do a little more indepth research and what not, just try to realize, both of you, that I'm not calling you a liar, just trying to explain to myself and others for learning reasons, that it might not be the way it seems. If you want to have a civilized conversation about it, we can start a new thread, but i'm not going to PM you as it's more of a learning experience than a pissing match for me.
