This TAMIYA high-performance rear-wheel drive R/C chassis assembly kit is constructed around a rigid monocoque with the main frame split into front and rear sections. It offers superior rear high traction drive characteristics and fuss-free maintenance of parts such as the easy-access differential. C.V.A. (Constant Volume Adjustable) oil shock-damped 4-wheel double wishbone suspension features dedicated long arms and steering linkage components for a range of setup options. A silky-smooth drivetrain utilizes full ball bearings, oil-filled gear differential unit and universal drive shafts. It can be assembled with a 210mm (S), 225mm (M) or 239mm (L) wheelbase, making it compatible with appropriately-sized existing Tamiya M-chassis body parts sets.
