Team Associated have introduced new chassis protective sheets for the T6.1, SC 6.1, and B6.1. Whether you race indoor or outdoor, protecting your chassis from premature wear will improve its lifespan and help maintain performance. These new Factory Team pre-cut chassis sheets are made from adhesive-backed 18-mil vinyl and offer a protective surface while looking trick with intricate details for that Factory Driver look. The sheets are printed in gloss black and include two extra tail sections to replace as they wear.
