mega Zs
I have mixed feelings about all these super upgrades for mini-z.
I can see the bearings, ball diff, xspeed motor(or any motor which does not require FET upgrade or poses a risk of burning out the electronics), and a selection front springs and h-bars. A long as you do not buy the kyosho brand ball diff you can keep th cost of these upgrades in the $40 range.
After those upgrades the cost goes way up and the benifit just a little.
One of the virtues of mini-z class is you can get their top car the MR-02 with a quality radio for $99. All you really need is some batterys and a charger.
