GRP has been making high quality for vehicles such as 1/8-scale buggies and sedans for a while and now they are offering two different treads for the Baja 5B. The Easy tread is good for on-road as well as hard packed dirt and the Buldog works with the loose stuff. Both treads come glued to either white or yellow dish wheels. According to GRP, the tire and wheel combo is 35% lighter than stock. You can get them at teamgonads.com and for more information check out a future issue of radio control car action magazine.
