Impression:
Black pig speed is pretty good. Can almost compare with 23T RZs. TRF oil shocks, motor heat sink is a MUST HAVE! Universial joints are also recommanded as the original dog bones are very easy to fall out. Also, front and rear A arms has small gaps on the shaft which needs spacers to make sure it fits. Otherwise, it might hit the "turning rods" while turning.
Suggest changing other parts while each starting to break down.
For every DF03 owner, be sure to add spacers on your front king pin. It's a designing failure as the king pin might move towards the steering and hit the steering rods. And here is my DF03 Dark Impact..... Just added 3 Racing metal steering cup and rear carbon shock towers last nigh...
