Our designers gave the RS4 Pro 3 all-new suspension geometry that delivers improved handling, with simple set-up options. The central battery mounting position and near-perfect weight distribution gives the RS4 Pro 3 a smooth transition between on and off throttle steering. The all-new layout delivers higher corner speeds & fast changes of direction. The all-new composite chassis keeps the suspension geometry exactly as our designers intended, ensuring the purest driving feel & clear feedback from the subtlest of set-up changes. Reduced radio interference, improved dampening, reduced parts count and lower price are additional benefits of the composite chassis. Lightweight composite, true bore, super low friction threaded shocks maximize wheel control under all conditions. They also lower overall car weight & center of gravity significantly. Graphite composite diffs and new short CVDs are standard, providing a significant reduction in rotating mass over the Pro 2. Faster throttle response and improved efficiency are the welcome benefits. Everywhere you look on the car there has been technological advances to bring you the best performance and value in the electric competition touring car class.
