The Novitec Group is one of the biggest tuners in the world, and depending on the model it is working on, it has a different name. For example, Novitec Rosso is working on Ferrari models, Novitec Tridente on Maserati, and Spofec with Rolls-Royce models. Spofec's latest creation is named Overdose and it is based on the Dawn Black Badge. If the name sounds familiar it is because a similar Overdose package was also applied to the standard Dawn a few years back.

What changes were made under the hood?

In base form, the Rolls-Royce Dawn Black Badge is powered by a 6.6-liter bi-turbo V-12 engine that delivers a total of 593 horsepower and 620 pound-feet of torque. It goes from 0 to 60 mph in just 4.9 seconds and up to a top speed of 155 mph.

The 0 to 60 mph sprint is also down a third of a second and it now takes only 4.6 seconds. Because we are talking about a very heavy car, top speed remains limited to 155 mph.

How about the exterior changes?

Like any other Novitec - err, Spofec, tuning kit - the Dawn Black Badge Overdose was equipped with a widebody kit made out of carbon fiber. The changes include modified wings, bumpers, and sills, plus an optional rear spoiler lip. The front fenders make the Dawn Black Badge 7 cm (2.75 inches) wider in the front, while the rear flares add 13 cm (5.11 inches) to the width of the convertible. The package also includes larger wheel wells that will offer space for extremely wide tires and wheels.

Spofec is also offering a new set of forged wheels in double-spoke design and sized 9.5Jx22 with 265/35 ZR 22 tires up front and 10.5Jx22 with 295/30 ZR 22 tires in the back.

At higher speeds, it automatically reverts to the original level.
