Over the last couple of years, we have been working alongside the MQB VW/Audi community to develop new wheel fitments specifically tailored by enthusiasts, for enthusiasts. Most notably, our newest MQB VW/Audi wheel, the 18x9.5” ET41 Forged SM-10RS, was engineered to offer the most ideal track-focused setup for the 8V RS3 chassis. We spent months engaging with HPDE enthusiasts to fine-tune the width, offset, and design of that wheel to cater directly to what the community wanted to see from a dedicated 8V RS3 track fitment.
Following the introduction of the 8Y RS3, we have received countless inquiries from enthusiasts searching for aftermarket wheel solutions specifically tailored to this new chassis. From these requests, we noticed a wide range of various fitment and functionality preferences across the board. Without a particular fitment having noticeably more demand over others, we decided to start from square one to learn for ourselves what the “perfect fitment” would be for this new chassis.
Over the last few months, we have gotten our hands on a couple of 8Y RS3s to play around with and to learn more about the chassis differences compared to the previous generation 8V RS3. After laser scanning the brakes, hubs, and suspension components, we pivoted to taking fender clearance measurements, as well as test fitting a few existing Audi wheels as a benchmark. Since these cars are still quite new and there isn’t much technical information out there yet, we figured it would be worth sharing with the community what we have learned thus far.
Much like the previous generation 8V RS3, the new 8Y RS3 comes with a 19” reverse staggered wheel & tire setup from the factory. However, while the 8V RS3 utilizes similar offset wheels both front and rear, the 8Y RS3 has a more unique factory fitment with significantly lower offset 19x9" ET25 front wheels, and higher offset 19x8" ET46 rear wheels. This configuration makes things a bit tricky when trying to run a true rotatable square setup, as large 18-22mm front spacers are required for a flush fit with the fenders and to match the track width of the rear wheels and tires.
While the factory reverse staggered fitment helps alleviate some of the understeer characteristics common on this chassis configuration, it is not quite as ideal for track applications, as you lose the ability to rotate your wheels and tires. 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.
Currently, we have tested and confirmed fitment with two of our existing MQB Audi wheels, the 18x9” ET42 Flow Formed SM-10 and the 18x9.5” ET41 Forged SM-10RS. Both of these wheels utilize a 5x112 bolt pattern, a 57.1mm centerbore, and have OE spec R13 lug seat recesses, making them a perfect fit for the 8Y RS3.
The 18x9” ET42 SM-10 is a bit more of a street-focused fitment and was tested with a 255/35-18 Michelin PS4S tire. In the rear, that wheel bolts right up and offers a flush fitment with the fenders without poking past them. Up front, we used a 20mm spacer to match the rear track width and to get a flush fit with the front fenders.


The 18x9.5” ET41 SM-10RS is a bit more of a track-focused fitment and was tested with 265/35-18 Falken RT660 200TW tires (which run quite wide for their size). In the rear, the fitment was a touch more aggressive compared to the rear of the 8V RS3. Since the car we tested was on stock suspension with stock camber specs, there was a bit of visual poke. However, one could easily dial-in that setup with some suspension and camber mods. Up front, we once again used a 20mm spacer to match the rear track width and for a flush fit with the fenders. With the 20mm spacer, there was a bit more fender clearance compared to the rear but we would still recommend running some additional front negative camber, especially with 200TW tires, to ensure a rub-free fit under suspension compression.



You can learn more about these two fitments, as well as a plethora of other details regarding the 8Y RS3 via our chassis specific fitment guide below:
While these rotatable square setups offer a solid starting point for this chassis, we understand that they aren’t exactly the best fit for everyone. Some folks prefer not to use large spacers, while others might prefer to use a reverse staggered setup similar to OEM. At the moment we are considering a couple of different wheel configurations for the 8Y RS3; a non-rotatable square setup utilizing a lower offset 18x9.5” front wheel that can fit without spacers, as well as a wider reverse staggered setup that will maximize wheel/tire size without spacers.
With that said, we are looking for your feedback to help fine-tune these all-new 8Y RS3 specific fitments. If you currently own an 8Y RS3, or have one on order, if you could please take a few minutes to answer a few survey questions, we would greatly appreciate it!
