The kits are about 70 element... Well do you want to use it as a buggy or what? Do you just want a low ride and small wheels? What you want? If you want to change it into a full blown buggy I recommend getting the Kit at [link=http://www.rcmodels.com/rc-cen-ffs025.html]RCMODELS[/link] it is about 70$ and supposedly if in a buggy form, it preforms alot better... About the tranny, I belive the kit gives you the instructions on what to do to make it a 1 speed and it comes with all the tools and parts I belive...
Why you want a buggy? MT form is alot more fun!!!!
