Audi S3 Wheel Fitment Guide

For both 8V and 8Y Audi S3 models, we recommend square setups ranging from 18" to 20" depending on your goals. The sweet spot for most enthusiasts is an 18" wheel, offering the perfect balance between performance and aesthetics. For the 8V chassis, OEM fitments include 18×8 +46 and 19×8 +49, while our aftermarket options range from 18×8.5 +35 to 19×9.5 +35 for a more aggressive stance. All our wheels are designed with the proper 5×112 bolt pattern and 57.1mm bore specifically for your S3, ensuring perfect fitment without spacers or adapters needed.

While technically possible, we don't recommend staggered setups for your Audi S3. The S3 uses a Haldex-based Quattro system rather than a "true" AWD system, and running significantly different sizes front to rear can cause drivetrain issues. For safety and optimal performance, all our recommended fitments for the Audi S3 are square setups, which ensure even tire wear and maintain the handling characteristics Audi designed for your S3.

The 18" wheel size offers the optimal performance balance for your Audi S3. This size provides the perfect blend of reduced unsprung weight, improved handling, and comfortable ride quality. Our 18×8.5" +35 wheels paired with 235/40 or 245/40 tires deliver enhanced responsiveness over stock without compromising daily drivability. If you're tracking your S3 or enjoy spirited driving, this setup will improve acceleration, braking, and cornering while still maintaining reasonable tire costs compared to larger wheel options. The 18" setup truly hits the sweet spot for both the 8V and 8Y chassis from a performance perspective.

Yes, 20" wheels will provide stunning aesthetics but come with some performance trade-offs. The larger diameter adds unsprung weight and reduces tire sidewall, which can impact ride quality and slightly reduce acceleration performance. However, if a show-stopping appearance is your priority, our 20" wheels for the S3 are engineered to minimize these drawbacks while perfectly filling those wheel wells. For those prioritizing form over function, 20" wheels with 235/30 or 245/30 tires create the look you're after.

Yes, all our wheels are specifically engineered to ensure proper clearance with your Audi S3's OEM brake system. We've conducted extensive research and development to guarantee perfect fitment without any clearance issues. This includes compatibility with the standard S3 brakes as well as many popular brake upgrades. However, if you've installed an aftermarket brake kit, we recommend consulting with our fitment experts before ordering, as different aftermarket brakes have varying caliper designs that may affect wheel clearance. Our team can help determine the best fitment for your specific setup.

Lowering your S3 significantly impacts wheel fitment, especially with more aggressive wheel and tire combinations. When lowered, the suspension geometry changes, potentially reducing clearance between the tire and fender during compression and turning. Some coilover designs can make fitment more challenging. If you're running lowered suspension like H&R springs or KW coilovers, we typically recommend staying with moderate offsets to avoid rubbing. For lowered S3s, our 19×8.5" +35 or 19×9" +40 options typically provide that aggressive stance without clearance issues, but your specific suspension setup may allow for even more aggressive fitments.
