Audi's B8 and B9 chassis hide serious capability under conservative factory wheels. Dropping unsprung weight with a forged monoblock wakes up the steering and lets quattro work with less mass at each corner. Forged Metallics wheels are forged from 6061-T6 aerospace-grade aluminum, up to 25% lighter than comparable cast wheels.
Which Forged Metallics wheels fit the A4, S4 & A5?
B8 and B9 generation A4, S4, A5, and S5 use a 5x112 bolt pattern with a 66.6 mm center bore — a spec we forge across the range:
- FM01 Stratos — forged 10-spoke, 18" and 19"
- FM02 Overdrive — forged multi-spoke, 18" and 19"
- FM05 Ronin — forged 5-spoke, 18" and 19"
- FM07 Vector — forged mesh, 18" to 22"
Eight premium finishes per design, priced per set of four with color-matched lug nuts included.
