What happens when German precision meets Japanese craftsmanship? When it pertains to cars, the outcome is pretty great.

Japan's 3D Design has revealed its own take on the new BMW Z4 with a new tuning kit shown at the 2020 Tokyo Auto Show that gives the roadster a more aggressive appearance without going too over the top. Among the visual upgrades include a front apron and a carbon fiber reinforced polymer rear diffuser for the M Sport 20i and M40i versions of the open-top Bimmer.

Sure, a Japanese aftermarket company could have simply turned its attention to the Toyota GR Supra. But let's face it, everybody seems to be doing that these days. In similar fashion, Germany's AC Schnitzer has also shown love to the Supra's platform sibling.

A ducktail spoiler made of urethane can also be fitted to all Z4 variants to provide additional downforce while giving the roadster an even sportier look. A stainless steel quad exhaust system set with 3.5-inch tips and a choice of 19-, 20- and 22-inch rims round off the exterior changes. Inside, 3D Design has enhanced the cabin with pedal kits and footrests, an upgraded steering with carbon fiber paddle shifters in cars fitted with automatic transmissions, aluminum handbrake levers, and new floor mats and trunk mats.

For now, 3D Design's BMW Z4 tuning kit only includes cosmetic upgrades, so the engine has been left stock. In the US, the BMW Z4 sDrive30i is powered by a 2.0-liter turbo inline-4 engine producing 255 hp and 295 lb-ft of torque, which is sent to the rear wheels through an eight-speed automatic transmission.

The range-topping M40i, on the other hand, packs a 3.0-liter turbocharged inline-six with 382 hp and 369 lb-ft of torque, enabling the roadster to do the 0-62 mph sprint in 3.9 seconds before topping out at 155 mph. Pricing for the 3D Design's tuning kit hasn't been announced, but the 30i starts at $49,700 while the range-topping M40i will set you back at least $63,700.
