New from VRP are Delrin bulkhead shims for your Team Associated B6 and B6D. Made from high quality Delrin, they are CNC cut at the VRP factory in Houston, Tx. These are used between the front bulkhead and the chassis. By shimming the bulkhead, it allows the front to roll a bit more. This can especially be good for tracks where you need just a little bit more steering. Each pack will include two .5mm shims.
