My 3rd gen got into a race with some nondescript Japanese sedan yesterday. I was doing fine until I felt that sinking feeling you get when the go pedal stops working at about 110mph. I have plans to go ahead and switch out to the V-rated Toyo Proxes and I've upgraded my valve train to handle the higher RPM's and the speedometer on my Edge can tell me how fast I'm going when I get over 120mph, but it is all pointless if I can't get around the dang 110mph limit. Any suggestions?
