They are constantly looking to bring our most hardcore R\/C racing fans the absolute best features able to be squeezed into a 1\/10 scale touring car chassis! After two and a half years of development, Tamiya brings you the ALL-NEW TRF421. The highest end touring car chassis series produced by Tamiya has received a whole new suspension and layout makeover!\u003cbr\u003e\u003cbr\u003eThis 2-belt driven 4WD carbon fiber double-deck design is loaded with features such as an updated drivetrain, a new lower deck shape, front and rear upper A arms, and shorter dampers, all of which promise to translate into serious speed on the track! Other notable features include a choice between one- and two-piece upper deck layouts for different chassis flex characteristics, plus updated suspension geometry that keeps the chassis more stable.\u003c\/p\u003e\n\u003chr\u003e\n\u003cdetails open=\"\"\u003e\n\u003csummary\u003e\u003cb\u003eKey Features:\u003c\/b\u003e\u003c\/summary\u003e\n\u003cul\u003e\n\u003cli\u003eThe Drivetrain uses a front direct coupling and rear oil-filled gear diff.
