The Ferrari 360 Modena replaced the F355 in 1999. The 360 featured an aluminum space frame that was 40% stiffer, yet 28% lighter than the predecessor 355's, despite a significant increase in size. The wheelbase grew by 150 mm (6 inches) to 102.4 inches. 18-inch wheels and tires remained standard, but 19s were fitted to some cars.
The 360's V-8 was enlarged to 3.6 liters and power increased accordingly; Max horsepower was now 395, reached at 8500 rpm.
Curb weight increased 20 pounds for the new model due to the engine and more equipment.

Ferrari continued to offer special models; see the Wiki for details.
A 360 Spider followed the 360 Modena and soon became more popular. The F1 transmission continued to be available and, though an expensive option, was often specified.
The 360 was produced from 1999 to 2004 and almost 18,000 were sold.
In 2004, a new F430 model was introduced. The 430 was built on the same space frame but had a 4.3-liter V-8 with 483 hp and a very substantial increase in torque. Curb weight actually dropped slightly with the new model, which featured standard 19-inch wheels and tires. Styling tweaks were part of the package, of course.
The F430 also introduced a steering wheel-mounted control called the manettino -- sort of a sport switch on steroids -- which varied the car's settings for throttle response, traction and stability control, etc. A spider model followed, of course, and sales of F1 automated manual models continued to grow. Special versions offered 503 hp power output -- see the Wiki for details.

Over 20,000 F430s were produced from 2004 to 2009.
The F430 was replaced by the 458 Italia, which I've already covered.
