During my vacation some upgrades for my mini-z arrived.
This includes a new set of rims and tires and a ball diff. The mini-z looks much better with black wheels and it is behaving very different with the much softer tires. I believe the lap times were halfed and now the motor can really be utilized. A more powerfull motor would be worthwhile.
The tires are really wearing fast. The wear is visible after each set of batteries and they won't last long.<br/>The ball differential is also a nice upgrade. It makes straight acceleration much easier. Turning does however change.<br/>All the upgrades are from PN Racing: http://www.pnracing.com
I also got a capacitor, some new H bars, some steel king pins and a silver Ford GT body. So far I have only used the king pins. These makes the front suspension really smooth.
I am really happy with the upgrades I have mounted so far. Next I will look into suspension and perhaps a new motor. Anyway it is just so much fun to make a track and race my brother, who has a similar mini-z.
