VZ Chassis

The VZ Chassis (Japanese: VZシャーシ, Byīzetto Shāshi) is a Mini 4WD Chassis released by Tamiya. It was officially unveiled in the 2019 All Japan Model & Hobby Show, which was held from September 27 to September 29, 2019. Neo-VQS was the first car to be equipped with the VZ Chassis.

General info

Being a successor to the VS Chassis, the VZ Chassis retains several aspects from its predecessor; it has the short 80mm wheelbase, and is equipped with the same gear set, terminals, battery switch type and propeller shaft. However, the chassis now comes with a carbon pinion gear by default.

The main chassis frame features a semi-multi-subframe design, which allow it to have a similar chassis strength comparable to that of the FM-A Chassis. Like most of the current chassis, the front bumper and the rear stay has been extended, and has the default configuration of a pair of rollers on the front and 2 pairs of rollers on the rear. Various attachment holes can be spotted on the main chassis frame, allowing it to be attached with various Grade-up Parts. The small battery clip on the chassis, which inherited from its predecessor, has been strengthened.

Whereas most latest chassis has their A parts molded in the low-friction POM (Polyoxymethylene) plastic, the VZ Chassis has its A parts molded in the standard ABS plastic. Instead, each VZ Chassis kits now includes a separate low-friction plastic bearing set, which minimizing power loss

What set it apart from other chassis is that the VZ Chassis comes with a user-removable front bumper, which is attached to the main chassis frame with a pair of truss screws. The VZ Chassis, as with the FM-A Chassis, features a removable rear stay. This allows racers to convert it to a bumper-less setup without the need for cutting or other such destructive modifications. However, it doesn't come with any skid bar by default. The removable bumper/rear stay setup also has the benefit of allowing cars based on real-world vehicles (For example, the Toyota GR Yaris and Honda e) to better resemble their actual counterparts, as well as in show-quality setups where the use of bumpers and/or rear stays may be deemed unnecessary or distracting.

Performance-wise, the VZ Chassis is similar to that of VS Chassis, but with the stability that is comparable to all co-current chassis (AR, MA and FM-A), while having better adaptability compare to the FM-A chassis. The chassis's multi-subframe design also helps on the toughness of the chassis.

Trivia

• The VZ Chassis is the first chassis to feature a user-removable front bumper.
• Despite being equipped with the carbon pinion gear by default, the VZ Chassis can be equipped with any of the 8t pinion gears.
