APEX ARC-8 Gloss Black 1-Piece Forged Wheels – BMW M4 Fitment (20-21in, 5x112)

The APEX ARC-8 is a 1-piece monoblock forged wheel finished in deep Gloss Black, featuring a multi-spoke Y-mesh face that pairs a lightweight forged core with an aggressive, track-ready look. Every ARC-8 supplied by ANKUSI is forged from 6061-T6 aluminum billet, then CNC machined and finished and quality-checked in our Guangzhou facility before shipping.

Featured fitment: BMW M4 (F82/G82 Coupe & Convertible) – 5x112 PCD, 66.6mm center bore. Factory M4 wheels run F 19x9.5J / R 20x10.5J at ET20 front and rear. ANKUSI fitment data for this chassis shows a flush setup at F 20x10.0J ET12 / R 21x11.0J ET14, stepping up to a max aggressive F 20x10.5J ET10 / R 21x11.5J ET12 before fender clearance gets tight. M4 owners chasing this stance commonly pair the wheel change with a KW V3 coilover kit and a big brake upgrade (AP Racing Radi-CAL 6-piston is a popular reference point) – always confirm clearance against your specific brake package before ordering.

Offset / backspacing reference (rear 21x11.0J ET14 example): backspacing ≈ 11.0/2 + 14/25.4 + 0.5 ≈ 6.6 inches. Useful if you cross-shop against backspace-spec'd parts instead of offset.

Available in custom PCD (5x112 and other 5-lug patterns on request), center bore, and offset to fit BMW M-cars and other 5x112 platforms. Contact ANKUSI for a fitment quote on your specific chassis and year.
