Tamiya TT‑02R
1/10 Scale 4WD Touring Car Chassis Kit
Overview
Race‑Ready Evolution of the Popular TT‑02 Platform
The Tamiya TT‑02R is a 1/10 scale electric 4WD touring car chassis kit designed as a high‑performance, race‑oriented version of the standard TT‑02. By combining the proven simplicity and balance of the TT‑02 with a comprehensive set of factory‑installed hop‑up components, the TT‑02R delivers improved rigidity, driveline efficiency, and suspension performance straight out of the box.
This chassis is ideal for club racing, spec classes, or builders who want a solid tuning platform without purchasing upgrades separately.
About the TT‑02R Chassis
High‑Performance Hop‑Up Components
The TT‑02R includes many of Tamiya’s most popular option parts as standard equipment, dramatically enhancing performance over the base TT‑02 chassis. Key upgrades include:
-
Aluminum motor mount for improved rigidity and heat dissipation
-
Aluminum propeller shaft and prop joints for smoother drivetrain operation
-
Aluminum rear uprights with 3‑degree toe‑in for increased high‑speed stability
-
Full ball bearing set throughout the drivetrain
These components reduce friction, increase durability, and improve overall handling consistency.
Shaft‑Driven 4WD Drivetrain
The chassis features a shaft‑driven full‑time 4WD system with front and rear gear differentials, delivering predictable traction and smooth power delivery. Metal drive shafts and reinforced joint cups enhance reliability during hard driving and racing conditions.
A high‑speed gear set is included, allowing the TT‑02R to be geared appropriately for track use with a wide range of pinion options.
Suspension & Handling
The TT‑02R uses fully independent double wishbone suspension at all four corners, fitted with CVA oil‑filled dampers and black coil springs. This setup provides superior damping control compared to friction shocks and allows the chassis to maintain grip through corners and transitions.
The suspension geometry supports camber and toe tuning, making the TT‑02R a flexible platform for both beginners and experienced racers.
Compatibility & Customization
With a 257 mm wheelbase and 190 mm touring car body compatibility, the TT‑02R accepts a wide range of Tamiya and aftermarket bodies. It supports brushed and brushless motor setups and can be further upgraded with adjustable suspension arms, differentials, and racing electronics.
