Audi RS4 B9 Facelift — Wheel Fitment & Specs
Overview
The Audi RS 4 is a high-performance variant of the Audi A4 range produced by Audi Sport GmbH for AUDI AG, a division of the Volkswagen Group. It sits above the Audi S4 as the fastest and most sports-focused car based on the A4's 'B' automobile platform. The original B5 version was introduced in late 1999 for main production from 2000, succeeding the Porsche/Quattro GmbH joint venture-developed Audi RS2 Avant. It was available only as an Avant (station wagon) and built on the Volkswagen Group B5 platform shared with the A4 and S4.

Aftermarket wheel sizes — read per position:
| Position | Width | Offset |
|---|---|---|
| Front | 8J–9.5J | ET10–ET31 |
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.
