    seriously?

    c'mon man, it's a z06 for crying out loud. they ONLY come with a 6spd.

    1st gear winds out to about 62mph in those cars. whenever you pull all the way to 7100rpms you can get a few extra mph's out of each gear.

    Plus the bigger wheels. When I was looking at a gear calculator, it showed as much as 3mph difference in ONE GEAR when going from a 325 to a 345.

    the 325 & 345 shouldn't affect mph unless one of the sidewalls are larger.

    They are a noticeably higher sidewall, even though they're both a 30 series. But if you plug in the numbers, just changing to a 345 will change the speed in each gear.

    In fact, Rob and I were laughing the other night because I ride people's asses all the time when I'm out, I even yelled at one guy for doing 5+ mph UNDER the speed limit in the left lane, then it hit me that my speedo might be off because of the tires lol

    Just so you know the "series" or tire height changes as a tire get wider. A 345/30 is not the same as a 325/30. I believe the way it goes the 30 is a percentage of the width of the tire. So sidewall height is 30% of tread width. Or something like that. That may be wrong(percentages part) but the principle of how the two change together is accurate.

    I swear to God I've got 3/4" more sidewall on these 345s, they made a pretty big difference.
