Models Covered in This Guide
2015-2021 Audi RS3 (8V)
The third-generation Audi RS3 is factory-equipped with massive 8-piston 370mm front brakes and a 19" wheel and tire setup in a reverse-staggered configuration. While the standard reverse-staggered setup provides the car with fewer understeer characteristics out of the box, the lack of being able to rotate the wheels and tires makes it less than ideal for track use. Taking into consideration the Quattro AWD system and front-biased weight distribution of the RS3, a rotatable square setup is a must to ensure even tire wear at all four corners. Shedding unsprung weight by downsizing to an 18" wheel will also improve upon the overall handling, braking, and acceleration characteristics of the car.
Our 18x9" ET42 SM-10 compliments the third-generation Audi RS3 perfectly for both street and track use. With a 5x112 bolt pattern and a 57.1mm center bore, our VW/Audi-specific SM-10 provides a complete bolt-on fitment without the need for centering rings, spacers, or hub adapters. Designed with brake clearance as a priority, the 18x9" ET42 SM-10 can also clear the massive factory 8-piston 370mm front brakes with room to spare.

Performance Street & Track: The Perfect HPDE-Ready Fitment For Your Audi RS3
(18x9" ET42 SM-10s in Anthracite W/ 255/35-18 Michelin PS4S tires)
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 RS3. 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 18" fitments are able to clear the standard 8-piston 370mm factory RS3 brakes with ease, as well as a variety of aftermarket BBK's. To see if these wheels can clear your specific BBK, please check out our brake clearance database at the end of this guide (coming soon!).
