Team SR introduce new weighted front bumpers for the Team Associated B4 and the TLR 22 platforms. Starting with the B4 variant, the front bumper is designed to replace the kit’s moulded plate with a 21g heavy and nickel-plated piece in order to adjust the weight balance of B4, T4 and X-6 cars. The special surface not only looks the part but also eliminates corrosion to make the part looking like new for a long time. The TLR 22 bumper is zinc-plates and a direct fit on the 22, 22T and 22SCT. Both plates help to mount needed weight as low and as forward in the vehicle as possible.
