I don't know if any one has used this before, but I think its a great toy for getting an idea of what you want to do with your truck or just about any vehicle. I have spent hours on this site. http://www.autowaretech3.net/nextwheels/andys_ecomm.htm

You can change ride height, tint and of course wheels. It's pretty self explanitory.

 

Dosnt work anymore though

That is so cool.....going to play now.

 

Thanks! I've been looking too.

 

Here's a good one too! Looks more realistic and offers a (somewhat strange) 3/4 view aswell for most wheels.
