whats your gear ratio
Just curious what your rear end ratio is? do you like it? Im already thinking i want to drop mine down a step or so. Plus with my 4:10 at 70 I'm at 2100 rpm.

4.10's here but with my tires it's like having 3.73's I wouldn't mind having 3.54's to get the rpm's down a bit more.

3:73 not bad with my 6-sp manual. I would not need anything lower.

4.10 in my 06, not sure what is in the 98 yet. It was jacked up a little, so it was a little lower but I would have preferred even lower (number wise) gearing to help out with mpg on the hwy

4:10s, wish I had 3:54s. Going to a taller tire is a cheaper way to cut the ratio down some. It's the route I took instead of changing gearsets.

3.73 and wish I had 3.54. Almost all of my driving is empty these days as I drive 34 miles one way to work each day. Also do a lot of travel for work that takes me approx. 700 miles from home about once a month on average. Again, empty commutes. One step taller gears would be real nice for my application!

Awesome didn't realize this would change that. Is there an easy way to adjust the speedo after? Would I need to?

A Smarty or Smarty Jr. will do that for you and I'm pretty sure it doesn't matter if the Smarty is already VIN locked. So, if you could find someone that already has one they should be able to help you out. Or for even more fun you could get one of your very own  .
