For weekend bashing and club runs, the Kyosho OT219S Main Chassis in silver gives the OPTIMA a tougher backbone. It is built to resist twisting and keep the car behaving predictably on varied surfaces.
The OT219S Main Chassis is cut to match OPTIMA mounting points and mounts cleanly to the existing hardware. The rigid plate reduces flex so you get more consistent handling under load.
Swapping the Kyosho OT219S is a simple task with basic tools. Make sure bolts are torqued evenly and inspect the chassis after heavy sessions to catch any loosening or wear early.
