Designed for the RO line, this main chassis uses a graphite-mixed resin to increase structural stiffness while keeping the original outline and mounting layout intact.
Because the geometry remains the same, the chassis is intended as a direct replacement for RO-series frames and will accept existing screw points and accessories without modification. The added rigidity shifts handling toward faster response and more immediate steering feedback, which can be beneficial on high-grip tracks.
Note that this part alters chassis flex and therefore tuning balance rather than adding mechanical systems. After fitting, evaluate suspension preload and anti-roll settings to regain the preferred balance between traction and responsiveness.
For racers running RO-series cars on high-grip surfaces, this graphite-mixed main chassis is a straightforward upgrade that tightens response while keeping stock fitment; follow up with a setup check after installation.
