Tamiya Toyota Celica GT-Four ST185 — TT-02 1/10 Shaft 4WD Touring Kit Overview
The Tamiya 58730 interpretation of the Toyota Celica GT-Four ST185 adapts the rally silhouette into a tidy on-road touring model. This kit presents the rally competition form as a lightweight polycarbonate body mounted on the TT-02 shaft-driven 4WD platform, retaining the visual cues and drivetrain layout that echo the ST185's competition origins.
Chassis and mechanical layout
The TT-02 chassis is engineered for predictable handling and easy maintenance. Its longitudinal arrangement places battery and motor to opposing sides for a stable weight balance. The shaft-driven 4WD system sits within a bathtub-type frame and uses front and rear plastic 4-bevel differentials, plus selectable gear ratios, giving straightforward setup choices for display or casual driving without heavy modification.
Body, wheels and scale presence
The shaped polycarbonate body reproduces the ST185's rounded fenders and rally-inspired cues. The kit includes five-spoke wheels with semi-pneumatic racing radial tyres sized to the 257 mm wheelbase, producing a convincing stance. Brake-disc style hubs and period bumper supports are included to enhance authenticity at typical display viewing distances.
Design and component characteristics
Component highlights include the bathtub-type frame, three-piece steering tie-rod, and four-wheel double wishbone suspension with friction-type dampers front and rear. Power is transmitted via a shaft drive with selectable overall gear ratios; the supplied configuration is one option among several available for the TT-02. The platform is intended to accept a Type 540 motor in its stock layout.
Who this kit suits
This assembly is ideal for hobbyists seeking a familiar, serviceable TT-02 platform together with a recognisable rally-derived body. It suits modelers aiming for accurate scale looks and a straightforward mechanical layout, as well as collectors who prioritise period-correct proportions and neat presentation.
