The BMW M8 Competition produces 625 hp from its twin-turbocharged S63 V8 and channels it through an all-wheel-drive system that already struggles to keep the rear tyres from overwhelming the front pair under hard acceleration. Every kilogram of unsprung mass you remove from each corner sharpens that balance. The stock cast wheels on the M8 weigh around 13 kg each. A forged monoblock replacement can bring that figure below 9.5 kg — a saving of roughly 14 kg across all four corners. That is weight the suspension no longer has to control, weight the brakes no longer have to accelerate and decelerate with every wheel rotation.
The Bete Noire Ver1.4 is a deep-concave multi-spoke design that fills the M8's wide arches without looking overwrought. The spokes are slim, evenly spaced, and taper gently toward the barrel, giving the wheel a turbine-like appearance from the side. It reads as purposeful rather than decorative — exactly right for a grand tourer that happens to be as fast as most supercars. In satin black, it disappears into the bodywork. In brushed aluminium, it catches light and adds definition to the car's flanks. Both options pair naturally with the AC Schnitzer body kit for the M8 F93.
| Bolt pattern | 5x112 |
| Recommended diameter | 20" |
| Width range | 9.5J front / 10.5J rear (staggered) |

| Centre bore | 66.6 mm |
| Material | 6061-T6 forged aluminium |
| Weight | ~30% lighter than equivalent cast wheel |
A staggered setup suits the M8's rear-biased torque split. Wider rears provide more traction under power, while narrower fronts keep steering response sharp. If you are considering a move from the factory cast wheels, the difference in forged versus cast performance is immediately apparent in turn-in speed and mid-corner stability.
The Bete Noire Ver1.4 comes from Hodoor's AI wheel design programme. The system generates thousands of unique wheel concepts daily, each validated for manufacturability as a forged monoblock. You are not browsing a fixed catalogue — the AI produces designs matched to a specific car's proportions, brake clearances, and visual identity. The design phase costs nothing. You pay only when a concept enters CNC production.
If the AI-generated options do not suit your taste, our in-house designer can work from hand sketches. Both routes lead to the same billet, the same machining process, and the same four-to-eight-week lead time.
Will these clear the M8 Competition's carbon-ceramic brake option?
Yes. The Ver1.4 spoke geometry provides adequate clearance for both the standard M compound brakes and the optional carbon-ceramic rotors at the 20-inch diameter.
Can I use these on an M8 Gran Coupe as well as the two-door?
The bolt pattern (5x112), centre bore (66.6 mm), and offset range are identical across the M8 Coupe, Gran Coupe, and Convertible. No fitment changes are needed. For help choosing the right wheel size for your M8, see our guide.
How much weight will I actually save per wheel?
Expect approximately 3-4 kg per wheel compared to the OEM cast units. Over four wheels, that is 12-16 kg of unsprung mass removed — enough to noticeably improve ride quality, braking, and throttle response.
