I am new to racing, which starts this weekend. I have been out there for several practice days - and have been advised that at least a rear bumper is recommended.
I do not hit others, I do my best to avoid other vehicles...but I have been rear ended during a practice day by a 1/8th truggy. Didn't know if some protection on the rear was common/necessary, or of the stock transmission setup protects the motor well enough.
