As standard, the RS5 Coupe rides on 19-inch lightweight forged wheels with 265/35 tires. Upon request, 20-inch wheels in various designs are available, among which the new, especially lightweight fully milled wheel. It uses 275/30 tires. Behind the big wheels are powerful RS steel brakes with perforated composite disks. At the front axle, these have a diameter of 375 millimeters (14.8 in), while at the rear, they measure 330 millimeters (13.0 in). The six-piston brake calipers with RS logos are painted in black, or optionally in red. Upon request, Audi can also equip the front axle with high-performance ceramic brakes featuring six-piston brake calipers and perforated disks with a diameter of 400 millimeters (15.7 in).
As an alternative to the further-developed electromechanical power steering, Audi also offers dynamic steering with RS-specific tuning. This uses a superposition gear to vary its ratio by up to 100 percent, depending on the car‘s speed and the mode selected in the Audi drive select dynamic handling system. At the cornering limits, the system countersteers with tiny impulses, thus further boosting the dynamism and driving safety. In the dynamic setting within Audi drive select, the superposition of the dynamic steering is stiff in order to support a more sporty driving style.
The axle concept of the new RS5 Coupe enables optimal absorption of longitudinal and transverse forces. A revised five-link construction is used on the front axle. At the rear, a five-link suspension replaces the trapezoidal-link suspension used on the previous model. This benefits the sporty driving characteristics and agility. It also improves comfort significantly. With the standard RS sport suspension, the new RS5 Coupe sits 7 millimeters (0.3 in) lower than the base model. Audi Sport offers the RS sport suspension plus with Dynamic Ride Control (DRC) as an alternative. It uses steel springs and three-stage adjustable dampers that are connected to one another via diagonal oil lines and a central valve. When cornering at speed, the valves regulate the oil flow in the shock absorber of the spring-deflected front wheel at the outside of the curve. They increase the support provided and reduce pitch and roll movements. They thus connect the vehicle more closely to the road and improve handling. A new damper generation with integrated control valve ensures much more noticeable spread between the individual modes of the Audi drive select system.
