JR Astralster Tamiya 18634 MS Chassis Mini 4WD Kit - Performance Focus  [18634]

Meet the JR Astralster by Tamiya 18634 - a compact circuit contender

The JR Astralster, model 18634 from Tamiya and shaped by Kota Nezu, combines tidy aesthetics with a chassis designed for adaptable setups. It is well suited to hobbyists who enjoy careful tuning for race days.

Closed body with subtle detailing

The bodywork is a closed profile finished in matte, with reflective window and lamp decals that catch light without being flashy. The shape keeps a classic Mini 4WD silhouette while offering room for cosmetic tweaks.

MS Chassis - solid and modular

The MS Chassis underpins the Astralster, offering a balanced platform that takes a double-shaft motor. Builders will find the chassis easy to assemble and straightforward to modify for handling or speed changes.

Practical upgrade routes

Performance improvements are straightforward: fit higher-rev double-shaft motors, try different gear ratios, or test tyre compounds to match track grip. The broad fenders provide clearance for a range of upgrade parts.

Set up for circuits and club tracks

On regulation Mini 4WD circuits the Astralster benefits from low-profile tyres on 5-spoke wheels, helping keep cornering predictable. Fine-tuning ride height and roll resistance is key to consistent lap times.

For Mini 4WD enthusiasts who favour balanced handling and upgrade potential, the Tamiya JR Astralster 18634 makes a thoughtful platform for development and race prep.
