401B Aero

Raceline 401B Aero: a clean monoblock daily wheel

The Raceline 401B Aero is a monoblock wheel with a tidy multi-spoke aero face, built as a straightforward, no-drama fit for compact and mid-size cars. It sits in the wider Raceline lineup as one of the brand's simpler street designs, with a single dark finish that works on a lot of platforms without fuss.

Sizes and fitments we stock

The 401B Aero comes in 15, 17 and 18 inch diameters. The 15s run 7 inches wide at a +15 offset; the 17s and 18s are 8 inches wide at +40. Bolt patterns cover 5x100, 5x108 and 5x114.3, which suits a broad range of imports and compacts.

Concrete examples in stock: the 5x100 15x7 +15 and the 5x114.3 15x7 +15 at the small end, the 5x108 17x8 +40 in the middle, and the 5x100 18x8 +40 up top. The +15 offset on the 15s pushes the face out for a more aggressive stance, while the +40 on the larger sizes tucks in for tighter clearance. Run the numbers against your car on the fitment calculator before you order.

Finish

The 401B Aero ships in Satin Black. If a darker look is the goal across your build, it lands alongside the rest of the black Raceline wheels; if you'd rather go lighter or brighter, browse the silver and gray Raceline options for other models.

Price and who it suits

Pricing runs $225 to $299 per wheel depending on size, with the 15s at the low end and the 18s at the top. That makes the 401B Aero a sensible pick for a daily driver or a clean OE-plus refresh where you want a solid dark wheel without spending big.

Want a different face in the same value bracket? The 141B Mystique Black offers a busier spoke pattern, and its 141S Mystique Silver twin swaps to a brighter finish. The 131B Evo Black is a mesh-style alternative, the 146B Matrix leans sportier, and the 145S Encore Silver is a split-spoke in a lighter tone.
