This Factory Pro roll spring mount, model O-TCPF08, is made as a Graphite 2.0 tuning component for use on the Tamiya TRF104 chassis in RC 1/10 touring car applications. It provides the mounting point for roll springs and is intended to let you adjust roll behaviour and roll centre characteristics precisely.
Fitting is a direct replacement for the stock roll spring mount on TRF104 layouts and needs only common workshop tools and the original fasteners. During installation confirm suspension alignment and spring seating, since small positional changes will alter roll response and the car balance.
Adopt a stepwise tuning method when using this mount: change one item at a time, log handling differences, and pair the mount change with spring and damper adjustments to reach consistent track results. This product is designed for RC-scale vehicles only and is not for road-use cars.
