ARC have introduced a new mid-motor conversion kit for the R11 2018 and 2019. The kit is designed to move the motor 25mm forward to a perfect position. This new engine layout provides more middle corner steering. The new middle motor bulkhead also allows more flex between front and rear end. The new upper deck can be installed in 2 different directions to provide different setup options and flex. That will change the chassis grip level and will offer a wider tuning window.
