Tamiya 15450 JR AR Chassis Tune-Up Kit - Basic Parts Set  [15450]

Quick look at the Tamiya 15450 JR Basic Tune-Up Parts Set

The Tamiya 15450 JR Basic Tune-Up Parts Set is a practical add-on for hobbyists who want to fine tune AR chassis Mini 4WD machines. The package supplies core upgrade parts intended to boost on-track stability and allow sensible customisation for racers of different experience levels.

Which chassis and what to expect

This tune-up collection is built around the AR chassis layout, prized for its front-engine balance and clean aerodynamics. It also fits many related frames such as PRO, VS and Super XX, giving flexibility to test settings across multiple Mini 4WD platforms.

What is included and how it helps

The set contains front and rear FRP plates, low-friction plastic rollers, mass dampers and stabilisers. These items help stiffen the setup, cut rolling resistance and damp unwanted vibration, which can result in more consistent lap times on bumpy sections.

• Front and rear FRP plates to increase chassis rigidity
• Low-friction rollers to reduce drag around guides
• Mass dampers to control vibration and bounce
• Hexagonal wrench tool for quick fitting

Fitment and assembly notes

Parts are made for straightforward fitting so you can install them quickly into an existing car. The included hexagonal plate wrench helps with plate and roller installation, making the kit approachable even for those new to Mini 4WD tuning.
