Brass body pins feature a slightly smaller diameter (.032″) then the aluminum pins which allow for more body float. The brass pins are also a little more durable then the aluminum pins. We use Brass pins on all RTR cars built here at Viper.
Note: We recommend a small strip of clear packaging tape to be placed over the body pins once installed in the body. This will not only keep the pins in but it will also reinforce the body.
