The BMW 8 Series hasn't been as successful as BMW hoped. As dealers struggle to sell inventories, the BMW M8 Coupe and M8 Convertible won't be going on sale for the 2021 model year in the US to help clear current stock. Consequently, the only new 2021 BMW M8 you can buy in America is the Gran Coupe.

However, owners of the regular BMW 8 Series Coupe and 8 Series Convertible can now spice up the styling as Japanese BMW tuner 3D Design is offering a new carbon appearance package for the stylish grand tourer. The changes are subtle, but they help make the 8 Series look more menacing for owners who don't want to splash out on the full-fat BMW M8.

Among the visual upgrades 3D Design has fitted include a new front splitter, side skirts, rear diffuser and rear lip spoiler. All of these components are finished in lightweight carbon fiber. While the photos only show these upgrades applied to the convertible, they are also available for the BMW 8 Series Coupe, with the exception of the rear lip spoiler. Custom 20-inch forged wheels complete the exterior makeover.

3D Design also recently gave the BMW X4 M the carbon fiber treatment. To make the interior more premium, 3D Design added a set of aluminum pedals and carbon fiber paddle shifters.

Don't expect any performance upgrades, however, as 3D Design hasn't tinkered under the hood - not that the standard BMW M8 is underpowered. The customized car shown in the photos is the BMW M850i, which packs a twin-turbo 4.4-liter V8 producing 523 horsepower and 553 lb-ft of torque paired with an eight-speed automatic transmission.

If you want more power, the range-topping BMW M8 Competition increases the output to 617 horsepower and 553 lb-ft of torque. Pricing for the carbon fiber upgrade hasn't been announced, but it will still be small change for owners that can afford the BMW 8 Series M850i's $121,400 starting price.
