[mikef350]

hi all

This is ny first step up to a decent buggy after being into olds hook tamiya and nitro models.

I bought a second handassociated b4 buggy and set about rebuilding it with lots new parts.its the stealth kit version with some nice factory team parts fitted and I intend to start racing with it this year so my question is can the newer b4.2 parts fit this buggy and is it worth doing
