Yeah Racing have added new carbon graphite option parts for the Xray T4. First up is the carbon graphite spur gear plate to help distribute stress applied to the pulleys more evenly when compared to the stock plastic piece. Next is the carbon graphite front body mount bumper brace used to better protect your chassis when compared to the plastic bumper brace that comes standard on the T4. Also new are two carbon graphite grip upper decks in 2.0mm and 1.6mm thickness. The 2.0mm is a direct replacement featuring high weave carbon which prevents deformation during high speed cornering resulting in a more stable car while the 1.6mm, more thinner than the original upper deck which allows for more chassis flex which in turn generates more grip. Next are the rear en front shock towers both made from 3.0mm carbon graphite. Both are a direct replacement from the standard shock towers. They feature high weave carbon which prevents deformation during high speed cornering and thus providing excellent high speed cornering grip. Also new are the “Equal Flex” grip carbon graphite chassis in 2.0mm and 2.25mm thickness. Both feature an almost perfect symmetrical cutout which will give you a more consistent handling chassis. The 2mm thickness chassis which is thinner than the original will provide more chassis flex which results in more mechanical grip, perfect for low grip conditions. The 2.25mm chassis which will give you a more consistent handling chassis.
