This lightweight and rigid 2mm-thick solid carbon soluble fbre remains are to be used in combination with straight back (item 15467) Sliding Dampers.

The roller stay is an essential element of wide sliding dampers, as it slides when the Mini 4WD car hits a fence, assisting it to soak up impact. Created from durable 2mm dense carbon fibre. Carbon soluble fiber remains offer an approximate weight preserving of 40percent over standard aluminum components. The Tamiya company logo is printed in white. Roller holes work printed size markings. Screws and washers, etc. are included for accessory. Can also be linked directly to the framework itself. Instructions show 2 examples.
