The Ferrari 458 might already be one of the greatest Ferraris ever, but Liberty Walk made it even better with this widebody kit, which is signed by Liberty Walk's founder, Wataru Kato. This is the first Liberty Walk Ferrari 458 widebody put together in the US and, judging by the reception, it won't be the last.

The Ferrari's naturally-aspirated 4.7-liter V8 now pumps out 585 horsepower instead of the factory version's 562 horsepower. The car is then equipped with Accuair suspension—hence the impractical ride height when stationary.

The popularity of SUVs has exploded in the US over the last two decades, which is why even Lamborghini felt that it had to make the Urus. The Lamborghini Urus is incredibly fast for an SUV, can go around corners better than most sports cars, and has an aggressive and sporty look to it that's hard to find in an SUV.

That's not quite enough for some people, however, which is why 1016 Industries has built this widebody kit. The kit includes a fender arch set, front aero lip, side skirts, a roof spoiler, trunk spoiler, and rear diffuser.
