In addition to the longitudinal dynamics, the motorsport specialists also took care of the transverse dynamics: The tuner from Bavaria upgraded the standard suspension with ABT sport stabilizers and ABT height adjustable suspension springs. This leaves customers free to decide on the level of lowering. A coilover suspension system with a special ABT shock absorber setup are also under development, in cooperation with the partner KW automotive. This setup provides a sporty-dynamic driving experience without neglecting the required comfort. Great performance needs a good basis: While the basic RS5 runs off the production line with 19 inch wheels, ABT Sportsline equips the coupé with its ABT SPORT GR 21 inch rims. The athletically styled wheels have not an ounce of unnecessary weight and feature a strongly concave rim base. The tire format is 275/25 ZR21.
