TB Evolution III 58299 Tamiya 1/10 Shaft-Driven Touring Kit  [58299]

Overview of the Tamiya 58299 TB Evolution III touring chassis

The TB Evolution series carries design ideas from earlier center-shaft platforms into a modern shaft-driven touring chassis family. The 58299 TB Evolution III advances that formula with focused mechanical updates: shifted motor and battery placement, a reduced-width lower carbon deck, revised driveline components, and controlled mass reduction. The kit aims for balanced handling, quieter drivetrain operation, and broad TRF-derived parts compatibility.

Principal mechanical changes

The motor sits on the right side while battery packs are located to the left to minimise driveline-induced steering inputs and to stabilise throttle behavior. Slimming the lower carbon deck by 5 mm helps centralise weight and limits chassis rubbing during aggressive cornering. The kit uses lighter differential outdrives and a revised centre drive shaft to reduce vibration and to enhance efficiency. An aluminium spur adaptor paired with a larger spur gear further reduces driveline losses.

Suspension and drivetrain notes

Suspension components trace back to the 414MII family, including arms, uprights, and adjustable suspension blocks that allow fine roll-center and anti-squat/anti-dive adjustment. The front one-way unit benefits from smooth-rotation concepts seen on other TRF-influenced models. Removing certain bulkheads and making selective component changes yields meaningful weight savings and a more agile steering response without unconventional build methods.

Recommended user profile

The TB Evolution III is aimed at hobbyists who prefer a dependable, shaft-driven 4WD touring base with a mix of carbon and alloy components. Its specification set and compatibility with TRF-style parts make it practical for competitive 4WD touring setups and for collectors maintaining TB-series lineage.

With measured updates such as a narrower lower deck and refined driveline parts, the TB Evolution III offers a consistent shaft-driven touring foundation suitable for tuners and collectors focused on TRF-influenced mechanics.
