YZ-2CAL3.1 chassis long-plate overview

This hard main chassis is produced for the YZ-2CAL3.1 family. Compared with the standard CAL3 main plate, the long-version increases wheelbase to promote a steadier platform at speed. The high-grip finish on the upper surface modifies tyre loading and cornering feedback.

Designed for drivers concentrating on chassis balance and track control rather than simple replacement, the plate alters how the car responds to suspension and weight transfer changes. Installation requires removal of the stock main plate and refitting using the YZ-2CAL3.1-compatible mounting points listed below.

Select this main chassis to gain a firmer baseline on grippy surfaces and a longer wheelbase to enhance straight-line stability and mid-corner poise; follow a stepwise approach to anti-roll and suspension settings when tuning.
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.

Will this long main chassis work with standard YZ-2CAL3.1 body mounts?

Yes, it is designed around the YZ-2CAL3.1 mounting layout. Check for any aftermarket body or accessory mounts that might conflict with the extended wheelbase and adjust placement if necessary.

Does the longer wheelbase require different shock settings?

The longer chassis often benefits from softer front shock settings or reduced front anti-roll to retain turn-in. Use measured changes and evaluate corner entry and mid-corner balance before further adjustments.

Are any chassis spacers or washers recommended?

Standard spacers and washers used on YZ-2CAL3.1 platforms should be suitable. Retain original hardware where possible and replace damaged pieces with items matching the vehicle parts list sizes.

What setup path is suggested after fitting the chassis?

Start with small reductions in front anti-roll or softer front spring rates to recover sharper turn-in, then fine-tune toe and camber for consistent tyre contact across the longer wheelbase and high-grip surface.
