{"product_id":"msr-021a","title":"Master Speed MS2.1 Aluminum Chassis Specification Assembly Kit","description":"\u003cp\u003e　The world's premier competition touring car reaches even greater heights. Specs derived from real-world data bring a vivid evolution to the speed category.\u003c\/p\u003e\n\u003cp\u003e　The front suspension geometry delivers an aggressive ride while reducing the burden on the driver, leading to relative improvements in lap times. It is now possible to select the lever ratio for the front suspension, allowing you to adjust the machine's cornering performance according to road surface conditions and decide the aggressiveness of the car in combination with tire choices. The shock components have also been refined down to the smallest detail to lower the center of gravity, and the mounting angles have been adjusted for the lengthened front suspension arms to perfect the overall balance.\u003c\/p\u003e\n\u003cp\u003e　The aluminum chassis specification promotes a lower center of gravity while drawing out ease of handling, enabling sharp cornering for everything from high-speed racing to sports driving on high-grip surfaces.\u003c\/p\u003e\n\u003cp\u003eNEW Parts\u003c\/p\u003e\n\u003cp\u003e■ Graphite Front Suspension Arms (1mm Long)\u003cbr\u003e■ Graphite Front Shock Tower\u003cbr\u003e■ Aluminum Front Lower Shock Mount\u003cbr\u003e■ Aluminum Rear Upper Shock Mount\u003cbr\u003e■ Front Stabilizer Wire\u003cbr\u003e■ Aluminum Motor Mount\u003cbr\u003e■ Aluminum Main Drive Pulley\u003cbr\u003e■ Shock Caps\/Shock Ends\u003cbr\u003e■ Shock Shafts (18mm)\u003cbr\u003e■ Shock Cap Balls (Φ4.8mm)\u003c\/p\u003e\n\u003cp\u003e※Photos show an assembled example. The kit does not include a 2-channel radio set (transmitter, receiver, speed controller, servo), battery (Li-po 2-cell), charger, motor, pinion gear, 1\/10 touring car tires\/wheels, 1\/10 touring car body, polycarbonate paint, etc. Please purchase these separately.\u003c\/p\u003e\n\u003cp\u003e　The upper arms are of an A-arm type that allows for full adjustment. Camber and caster can be changed variably, allowing you to fine-tune the steering feel to your preference.\u003c\/p\u003e\n\u003cp\u003e　The shock mounting positions have also been optimized to match the changes in shock length and suspension arm length.\u003c\/p\u003e\n\u003cp\u003e　The screws used from the underside of the chassis are new flat-head screws with a 120-degree taper to match the plate thickness. Designed for use with a 2.0mm socket wrench, they provide secure part fixation in combination with high screw precision.\u003c\/p\u003e\n\u003cp\u003e　The servo mount retains the style of securing from the bottom. Integrated with the bellcrank base, it is unaffected by chassis twist, ensuring neutral handling characteristics.\u003c\/p\u003e\n\u003cp\u003e　The shock shaft has been shortened by 0.9mm, and the shock caps and resin parts have been newly designed to achieve a shorter shock length while maintaining cylinder capacity.\u003c\/p\u003e\n\u003cp\u003e　The aluminum motor mount has also been newly designed. The motor position is 0.5mm higher than before, optimizing weight balance for both aluminum and steel chassis.\u003c\/p\u003e\n\u003cp\u003e　Additionally, the shaft holding the center pulley has been extended, bringing the bearing inside the pulley closer to the spur gear. This reduces the offset between the pulley and the spur gear, minimizing vibration and preventing gear damage.\u003c\/p\u003e\n\u003cp\u003e　In the rear, the shock mount has been changed. The upper shock position is adjusted to match the shock length.\u003c\/p\u003e","brand":"YOKOMO","offers":[{"title":"Default Title","offer_id":67616689782893,"sku":"MSR-021A","price":121000.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0722\/1133\/3229\/files\/msr-021a.jpg?v=1791248869","url":"https:\/\/www.teamyokomo.com\/en\/products\/msr-021a","provider":"YOKOMO 公式サイト","version":"1.0","type":"link"}
