Audi S4 B8 — Wheel Fitment & Specs
Overview
The Audi S4 is the high-performance variant of Audi's compact executive car, the Audi A4. The original S4 was built from 1991 to 1994 as a performance-oriented version of the Audi 100 sedan. Since then, all subsequent generations have been based on the Audi A4 platform, evolving alongside it. Each generation has featured longitudinally oriented front-mounted engines and Audi's quattro all-wheel drive system with a Torsen-based center differential. The S4 is distinguished by its more powerful engine, upgraded brakes, firmer suspension, larger wheels, distinctive styling cues, and exclusive badging compared to standard A4 models. It competes in the compact executive car segment against vehicles like BMW's M3 series and Mercedes-Benz C-Class AMG variants.

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.
