1. Turn your capslock off.
2. Mike is the only person who sells them-
HERE. For cases, you can either use the FLM hybrids-
HERE, or the UE Ultralite cases-
HERE you will need two sets, and some 8x10x0.2 shims.
3. My truck? Sick it is, but fast it isnt. I'd say about 30mph tops with the Hvmaxx 6.5 I have. It will be alot faster once I get a new BL system next year...
4. If you already have the Hv4.5 for the buggy, then its well worth a try, but otherwise I would recommend reading around the forum for more ideas.
