Thanks for this info guys. Gives me something to think about. Since I just did a ratio swap in the fall and have barely driven the car since, I can't bring myself to switching ratios again.
I drive 90% in the city but do like to head out for an extended road trip once in awhile. I'm just nervous about running 3000+ rpms at highway speeds for extended periods. I think I'm still gun-shy from my overheating NIGHTMARE last summer!
If I had to do it again, I wouldn't have gone with 3.55's. Should have dropped down a ratio. Although I am really happy with the "get up and go" off the line now!
So it sounds like the added expense of 15" wheels and tires may not be the answer. Hmmmm...........
