ARC have introduced the R8.0 2016 1/8th nitro on-road kit. Combining all the features of the successful R8.0, the 2016 model includes selected, previously available option parts as well as new features designed to make maintenance easier while improving reliability at the same time. The flex 2-speed bulkheads are now included as standard, they provide more flex in the rear of the chassis resulting in improved rear end traction. Another feature of the flex bulkheads is a 1.5mm higher layshaft position which helps prevent the spur gears from touching the track surface under extreme cornering which can lead to failure. Also included is the drilled and thus vented brake disk that gives a more linear feel as it helps to reduce brake temperature for less brake fading
Also new with the 2016 kit is the O-ring retained rear layshaft pulley that does away with the usual E-clip fitment for a lighter weight and easier replacement and the O-ring system has also been employed on the front one way assembly to reduce weight and improve maintenance. The kit is rounded out by a new rear lower shock mounting plate that has been designed with an additional hole. The new location moves the lower shock mounting position further out on the arm and has shown in testing to provide more traction in high speed corners. The 2016 spec kit is meant to hit the stores soon.
