I have a new RTR B4.1 and the only thing I've done to it is put double D tires on the back. I'm somewhat of a rookie to all this, so I ask you all this.
What would be the first thing I could do to this car that will improve performance? I am more interested in handling improvements rather than speed. I run entirely on outdoor clay tracks which vary from somewhat hard with no dust to fairly dusty once everyone has run on it awhile.
Thanks, Rick
