I decided to upgrade the steering in the top spec DRB. I'm actually contemplating a full OD conversion...
This set comes with everything you need.
But thats irrellevant anyway. Because the Overdose DIB/DRB Ackerman Steering set I upgraded further with sealed bearings and ball joints and nuts as well as titanium screws.
Nuts! is right.
The blue ball joints were Tamiya... wrong size. a bit of binding resulted in unpredictible chassis. I switched back to titanium ones and used a small spacer and all was well.
