Well, I may look out for a 3.55 third member then. It does drive well with the 3.91's. Just want a little more on the freeway for some longer trips. I also really like the new PTC 9.5.
If you want a higher gear for the freeway then go with the 3.55 gears. Sounds like the car is more of a driver than an all out drag car so make it work for what you want it to do. It isn't going to slow down much at the track. In fact, if it is traction limited then it might actually leave the line better with the taller gear.
