Long-version YZ-2CAL3.1 chassis explained

This hard main chassis is tailored for the YZ-2CAL3.1 range. Its extended wheelbase gives a longer footprint than the regular CAL3 plate, improving stability through fast sections. The top has a high-grip finish to change tyre load distribution and cornering feedback.

It is aimed at racers adjusting chassis balance and on-track control rather than those seeking a like-for-like replacement; the new plate affects how suspension and weight transfer settings work together. Fitting the part involves removing the stock main plate and reassembling using the YZ-2CAL3.1 mounting points shown below.

Opt for this chassis when you need a firmer baseline on grippy surfaces and a longer wheelbase to enhance straight-line stability and mid-corner balance; combine with measured suspension and anti-roll changes to tune for your track.
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.

How should I alter camber and toe after fitting the long chassis?

Begin with small camber reductions to keep the tyre contact patch even under cornering. Slight front toe adjustments can help restore turn-in on the longer wheelbase; always test changes incrementally to observe their combined effect.

Will the high-grip top surface change shock tuning?

Yes. Increased traction can transfer more load into the suspension, so you may need to soften damping or spring rates slightly to retain predictable mid-corner behaviour and prevent early tire breakaway.

Is the plate suitable for both practice and race settings?

The long, high-grip plate is useful where stability and consistent traction are priorities. For loose or low-traction surfaces you might prefer the standard plate; use this long version when the track rewards extra wheelbase and grip.

What suspension changes should I try first?

Try reducing front anti-roll and softening front spring rates initially to recover front-end bite, then refine rear roll balance to keep the car stable mid-corner on the longer chassis.
