Do you have a automatic or 5-speed ? You should go one set higher for a automatic because of the way the trans. is geared. Therefore a 3:73 on a auto. is the same as a 3:55 on a stick. If you have a auto go with the 3:73 to keep from having all of your power right out of the hole and go with a 3:55 on a stick for the same reason. 4:10s are to high on either car unless you have gumdrops for tires. Hope that helps.
