Tamiya 58720 TT-02 Type-SRX 1/10 On-Road Chassis Kit - Track Upgrade Base  [58720]

Track-focused Tamiya TT-02 Type-SRX for serious racers

The Tamiya TT-02 Type-SRX chassis kit is aimed at hobbyists who want a robust, upgrade-friendly platform. With parts aimed at improving durability and precision, the kit lets builders create a race-ready 1/10 on-road car while learning setup and tuning techniques.

Performance-Boosting Upgrades

This SRX variant includes key components like the 37mm drive shafts suited for double Cardan joint shafts and an XV-02/TT-02 oil gear differential unit, all selected to sharpen handling and stability. The addition of TRF419 suspension upgrade parts and a high-torque servo saver improves steering response for competitive track use.

Hands-on Skill Development

Designed as a step up from entry-level kits, the TT-02 Type-SRX gives builders room to experiment with gear ratios and suspension tuning. The fully independent double wishbone layout makes it easy to test settings and refine driving technique before moving on to more advanced Tamiya models.

How the SRX Compares on Track

Compared with other TT-02 variants such as the TT-02R, the SRX stands out thanks to reinforced propeller joints and lightweight aluminum diff joint cups that cut weight while increasing strength. The TRF420-inspired suspension elements add a level of adjustability that benefits lap times and tyre life.

The Tamiya TT-02 Type-SRX delivers a practical, tunable chassis for racers who want reliable parts and clear upgrade paths. It is well suited to those sharpening setup skills and seeking consistent lap performance.
