Hey guys I just sign up with the local racing club, and just received my RC8T RTR. The next races are not until the end of the month so I am getting ready now. I have seen in pics in magazines that some people but some type of dirt or mud gaurds on the rear arms of their truggies. Do these serve their purpose? Are they necessary? I've been searching on the forums and haven't seen much info on these. If anybody can help, or put their input I am all ears.
