As mike says the tom yardy setup is what you need, Joe ran the bmax last year on this setup (although he reckons tom used joes setup
), the only difference is joe uses associated shocks with front 35wt, no2 piston and silver spring and rear 30wt losi orange piston, silver spring, the standard Yokomo diff balls are made of cheese, joe uses Vampire and very good they are.
tom also uses a roll bar a lot, joe doesn't like it despite tom telling him to use it!!
