How this chassis influences setup

This graphite main chassis provides the mounting foundation required to attach a BD10 standard 2mm long suspension arm to a BD9 car. It locates the arm precisely and contributes to consistent front-to-rear suspension geometry under dynamic loads.

Compatibility is centred on BD9 installs and the unit is listed for use with the MRTC-BD919S chassis. The graphite's stiffness and vibration damping are common tuning tools for drivers seeking crisper steering or altered mid-corner balance without electrical modifications.

Installation notes: replace the stock BD9 main plate when fitting the BD10 2mm long suspension arm. The part keeps standard bolt-on points; installation generally requires removing the factory plate, fitting this graphite chassis, and checking for steering and suspension clearance. No extra hardware is provided, so reuse OEM fasteners or suitable replacements.

For racers fitting a BD10-standard 2mm long suspension arm to a BD9-based car, this graphite main chassis supplies a repeatable, stiff mounting platform that supports precise setup changes.
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

What setup differences should I try after fitting the graphite plate?

Expect a firmer chassis response; start by softening front roll stiffness or adjusting front shock compression to rebalance initial turn-in and mid-corner behaviour.

Does the graphite plate change steering sensitivity?

Yes, increased torsional stiffness often sharpens steering feedback. Small steering trim and toe adjustments may be needed to fine-tune on-track feel.

Should I alter damping settings after installation?

Many tuners reduce front damping slightly to regain compliance; perform incremental changes and test to see how the chassis stiffness interacts with shock tune.

Does the new chassis affect corner weighting?

It can alter corner weight distribution because of the stiffness change; recheck corner weights if you are pursuing precise balance and lap time improvements.
