4.10s gear top out 110 mph?

You'll lose a little top end but not that much. 110 maybe in the V6 but the GT still has enough torque to put you in the 130's or possibly higher. With my 3.55's and 275/40/18's, the aerodynamics all but kill whatever is left power-wise at a bit over 150 MPH where I'm turning only about 4600 RPM in 5th. I redline in 4th at about 144 MPH.
PM me with your email for an RPM vs. Speed spreadsheet where you can input your setup. It's damned accurate (for me).

Really? Factory is 6250. Brenspeed set mine at 6800 which scared the heck out of me so I dialed it down to 6500. I've bounced off it numerous times at 6500 but I'd chit myself if I set it above 7000 and bounced off it. 7500 and it didn't fly apart? I'm impressed.

You will have no problem breaking 110mph with the 4:10's, I can easily hit 150mph in mine but that is about as high as it wants to go, like the guys say, aerodynamics take over at that point.
