cars for boys

These dies are from sets that are for kids - some one gave them to me, and I struggle to use them in my Cuttlebug - I added half a dozen pieces of cs for shims in order to get them to cut.  Do any of you use them?  Suggestions?  Another suggestion for Cuttebug - how about a different HB folder?  A horizontal one would be nice!  The DP is Paper Pizzazz.
