Product Details
The Apex ARC-8 in 17x8.5" ET20 Race Silver is a flow formed wheel that's hub-centric on the E30 3 Series (non-M3). The ARC-8 has been Apex's best seller for more than 15 years, and it's the lightest, most affordable flow-formed wheel in the lineup. Its muscular design is just as at home on a daily driver as on a track car.
Turner's take: The OG Apex wheel, with a classic motorsport-inspired Y-spoke look.
Features
- Flow-formed for low weight at an approachable price
- Deep concave spokes in select sizes
- Open hub center for fast wheel swaps at the track

Good to Know
Will it fit my BMW?
It matches the 4x100 bolt pattern and 57.1mm hub, so no hub rings are needed. Our vehicle fitment list confirms bolt pattern and hub only, not front or rear placement. Most BMWs use different widths and offsets front and rear, and some models also change diameter or center bore between axles. Offsets outside the usual range can sometimes work with wheel spacers and longer lug bolts. Big Brake Kits (BBK) and widebody setups also affect clearance, so confirm front and rear fitment for your car before ordering.
What lug bolts does it use?
60° conical-seat lug bolts. BMW factory bolts are ball seat and can't be reused.
Does it come with a center cap?
It comes with an Apex gloss black center cap, and BMW OEM caps also fit.
Is this one wheel or a set?
Price is per wheel. Check your front and rear sizes first, or choose one of our matched Apex wheel sets.
