Audi S4 B8 Facelift — Wheel Fitment & Specs
Overview
The Audi S4 is the high-performance variant of Audi's compact executive car, the Audi A4. Starting with the B5 platform in 1997, each generation has been based on its respective A4 model, evolving alongside it. The S4 features a longitudinally mounted engine and comes standard with Audi’s quattro all-wheel drive system using a Torsen-based center differential. It distinguishes itself from regular A4 models through enhanced performance characteristics such as upgraded brakes, firmer suspension, larger wheels, distinctive styling cues, and powerful engines. In markets without the higher-performance RS 4 variant, the S4 serves as Audi's top-tier offering in the compact executive car segment.

Aftermarket wheel sizes — read per position:
| Position | Width | Offset |
|---|---|---|
| Front | 7.5J–8.5J | ET24–ET45 |
As a rule, each extra 1J of width wants roughly +8–10 ET to keep the wheel tucked. The exact offset and any spacer are confirmed by the fit-check.
