Thanks for the reply. THe car is set up like a character, kind of like a quadraped. ANd I Used SDK to Deform the Springs and such... SO each wheel is indiviually animated on the Y axis, they are parented to bones, and everything is parented to a locator that is animated along a path. I have rigged it so that you get the proper rotation point of the wheel, so that it doesn't just go up in down, but also pivots side to side, depending on how close to the wheel well it is. Thanks, Brian
