ARC have introduced their new R11 Mid middle motor chassis conversion kit for the 2019 and 2018 specification R11 touring car. The new layout moves the motor 25mm forward for improved weight balance, helping the car to gain steering and rotation mid corner. The updated motor bulkhead also ensures more event flex distribution between the front and the rear end which further helps with overall balance. The torsional flex of the upper deck and chassis is adjustable by two different flex plates and the new design upper deck can be mounted in two different directions to provide different setup options and a wider tuning window. The set includes the new upper and lower decks, flex plates, motor mount, centre pulleys, belts as well as mounting hardware and it is available now.
