2017-Present Audi S5 (B9)

The B9 generation Audi S4 & S5 offers refined performance for spirited street driving right out of the box. However, with the right modifications, these cars can be quite competent out on the track. Equipped with a potent and powerful single turbo 3.0 liter V6, paired with Audi's legendary Quattro AWD system, the B9 S4 & S5 are a popular choice for enthusiasts that drive year-round, even in inclement weather conditions. 

Our 19" Forged VS-5RS and Flow Formed SM-10 wheel designs both compliment the aesthetics of the B9 S4 & S5 quite well, while offering a variety of features and price points to best cater to your specific driving preferences. The VS-5RS and SM-10 were both developed with brake clearance as a priority, allowing them to clear the factory 350mm brakes on the B9 S4 & S5 with plenty of room to spare. Furthermore, these wheels utilize a 5x112 bolt pattern with a 66.6mm center bore, which allows them to fit without needing centering rings or hub adapters.

Important note regarding wheel hardware: Since these wheels were engineered to use 60 degree conical style hardware, you will need to replace the factory Audi R13 ball seat lug bolts with aftermarket conical style lug bolts or nuts. We offer a full Audi stud conversion kit complete with 19mm conical style lug nuts to support these wheels, which you can find on our website here: APEX 75mm M14x1.5mm Stud Conversion Kit W/ 19mm Conical Seat Nuts

These fitments are the perfect match for weekend track warriors and hardcore racers seeking to maximize the wheel and tire size that they can fit on their Audi B9 S4/S5. These aggressive wheel specs will occasionally require supportive modifications commonly found on track cars, such as increased negative camber. While certain configurations can provide a complete direct fit on a stock car, additional modifications may be required for a rub-free fitment depending on your suspension setup and specific tire selection. With a focus on brake clearance, our 19" fitments are able to clear the factory 350mm S4/S5 brakes with ease, as well as a variety of aftermarket BBKs.
