ARC R8.1 2017 1/8th nitro on-road car kit

ARC have introduced the R8.1 1/8th nitro on-road car. The latest version comes with an all-new chassis design that utilises a sliding weight system in the front that allows to easily and conveniently adjust the weight bias using a sliding brass weight. Also new is the Flex Upper Deck that has become a standard part and that allows to adjust the front end flex by installing or removing a Y-brace. A similar system in the rear of the car helps to further fine-tune the overall torsional flex of the car.

While being in the rear, the 2017 kit comes with a new rear anti-roll bar that was designed to sit further forward which results in a more linear action, increasing the overall stability of the car. Another new feature for the R8.1 is the updated rear block that allows to run a longer rear arm setting for improved traction especially under acceleration. To go with the new rear end geometry ARC have included extended length rear shock absorbers that gained 6.5mm in length while the shock position also received an update with the units leading more towards the cent of the car, leading to better response. Last but not least come several new transmission parts such as a new centre layshaft block that makes for improved shaft and bearing life while the lightweight transmission profits of a new aluminium clutch bell, all wheel axles are now made of aluminium and front and rear CV-style driveshafts come as standard. Beside the full kit ARC will also offer an upgrade kit, allowing R8.0 users to upgrade to full R8.1 2017 specifications.
