AR Chassis

AR Chassis

The AR Chassis (ARシャーシ) is a Mini 4WD chassis released by Tamiya in 2012. It was first seen with the release of Aero Avante.

It has the same long wheel-base as the Super-TZ Chassis has. Because of this most premium version of the early minicars with Super-TZ Chassis has been using AR Chassis.

Unlike most of the chassis, it features the aero-dynamic designs all over the chassis, and batteries and motor can easily swap out by remove the under chassis parts, providing excellent maintenance.

The front and rear bumpers has been extended and there's muitiple screw holes to provide better parts attachments. Unlike the previous chassis, the secondary parts (including rollers and bearing) were molded in the low-friction POM plastic and this eliminates the brass bearing parts all together. The rear bumper is not removable by design. There's the brake skit bar attached under the rear bumper.

There's also several air-ducts that are made to cooling the batteries and motor while running.

Performance-wise, it performs better than any rear-motor shaft-driven Mini 4WD chassis to date, however due to its weight, its cornering and acceleration performances is a little inferior than that of Super-II Chassis.
