Hey. I just got my Ultra Comp 2 and I love it. I took it around for a few laps at the local bmx track and had a blast. I noticed that the front tires are pulling a lot more than the rears (rear don't pull much at all, I got a front wheel-drive buggy) so i'm going to change the center diff oil. Any suggestions on which oil to use? I don't know what visc. the stock stuff is. Also, i'm going to get stiffer springs. When I jump it, it lands flat but hits the chassis. I guess I should use a thicker oil but I don't know what the stock stuff is either. Also don't know what the stock springs are. All I know is they are black. And, one last one. Who makes those crimefighter tires you were talking about. I'd like to get them. Thanks.
