21" OEM+ with D4 S8 Wheels
Looking for feedback from anyone running OEM Audi 21" wheels on a B8/B8.5 A5/S5. I have a 2011 S5 Coupe (4.2 V8, 6MT) and I'm considering a set of OEM Audi S8 wheels for an OEM+ look.
Wheel specs:
I've attached a quick rendering of how they might look on the car. My goal is not a show-car or stance build. I'm after a clean OEM+ appearance using genuine Audi wheels. What I'm hoping to hear from people with actual experience:
Thanks!
Wheel specs:
- Audi OEM Part #: 4G8601025AR / 4G8601025AQ
- OEM application: 2017-2018 S8
- Size: 21x9
- Offset: ET35
- Bolt pattern: 5x112
- Center bore: 66.6mm
- Same 5x112 bolt pattern
- Same 66.6mm center bore
- Width increases from 8.5" to 9"
- Offset changes from ET32 to ET35
I've attached a quick rendering of how they might look on the car. My goal is not a show-car or stance build. I'm after a clean OEM+ appearance using genuine Audi wheels. What I'm hoping to hear from people with actual experience:
- Are you running 21s on a B8/B8.5 A5/S5?
- Any rubbing issues?
- Any suspension clearance concerns?
- How much harsher is the ride compared to 19s?
- Any regrets going to a 21?
- If you went back, would you choose a 20 instead?
Thanks!

Should fit. and ride like a skateboard.
Not 21's but my car had "hot wheels" worthy 20's and was static slammed. switched to 19's with a mean inset. no issues. - not even close to any arms or shocks
I'm only concerned that you'll rub the fenders. Because inside? plenty of space.
Same suspension architecture should be fine. with updated rims and tires. can you test fit?

Thanks for the reply. Unfortunately no options to test fit. I'd have to shell out some bucks for at least one wheel/tire setup and mock up. Maybe if I see some take-offs on FB locally I could arrange a test fit.
When you say ride like a skateboard I assume you mean harsh. Someone else said it'd ride like s*!t.
