Much like past CS models, the F430 will go on a diet that includes more fiber (carbon, that is) replacing the door panels and rear grille, along with magnesium wheels. Unlike its predecessors, those wheels will be attached via a five-lug setup, as opposed to the single hub units used on the F360. Plastic windows also won't make it to production, as safety regulations won't allow them. Regardless, the F430's weight will still drop by over 200 pounds.
In addition to the weight savings, more power will find its way under the hood. Currently, the base F430 makes approximately 490 BHP. After some exhaust modifications that move the pipes northward and the expected ECU tweaking, the new CS will produce upwards of 520 BHP. Naturally, all that 'go' needs to be scrubbed off at some point, so Ferrari upgraded the brakes with larger discs and fitted stickier rubber at all four corners, to maximize both acceleration and braking.
The F430 Challenge Stradale should be made available sometime in early 2007.
