Oakley Design, which has received acclaim for its packages for the Porsche GT2, GT3 and Panamera, says that through revising the ECU it is able to raise maximum power from the standard 458 Italia's 560 bhp by 58 bhp, to bring it up to 618 bhp, while peak torque also benefits by 20 Nm, from the production model's 540 Nm it now climbs to 560 Nm in the Oakley Design version.

Oakley Design, which has forged its reputation on providing exclusive packages for an array of Porsche models and is closely involved in the "track day scene", claims that a new carbon-fibre front lip spoiler improves front axle's downforce by 45 kg at 240 km/h, this was verified by wind tunnel testing, which will benefit drivers who use their 458 Italia for track events, while the new racecar-style centrally positioned radiator vent now channels air out over the bonnet instead of under the car. This vent also helps to boost the airflow at the base of the front windscreen, benefiting overall aerodynamics. A "Gurney Flap" fitted to the rear spoiler adds a further 25 kg of downforce at 240 km/h over the rear axle. Further aerodynamic improvements come from new horizontal-profile side-skirts and new diffuser sections at the rear.

Weight reduction has been tackled by incorporating a new roof section made out of carbon-fibre as well as the use of similar composite materials for the door mirrors and air vents, with weight kept down as the additional new spoilers, side skirts and diffuser are also all made out of carbon-fibre. Oakley Design has also developed a new custom exhaust system that disposes of the standard bypass valve and it claims that this sheds a further 30 kg from the 458 Italia's overall weight.
