Ferrari build an alternative to dampers!
Wheelbase also has an important effect on the frequency that the chassis vibrates at, thus effecting damping rates, etc.
A longer wheelbase car will vibrate at a lower frequency than a short wheelbase car. This is easy to understand because if the front wheels hit a bump, the time it takes for the rear wheels to hit the same bump will setup a vibration at a specific frequency tied to the wheelbase.
There is a reason that every land speed record car has an extremely long wheelbase. At high speed the frequencies increase so drastically with a short wheelbase car that it is not damped by the chassis and the car becomes incredibly nervous and unstable.

the tyres supplied by bridgestone this year are based on the 2004-05 construction and with compounds unrelated to the very trick and expensive ones that helped ferrari to a strong 2006.
testing at barcelona and jerez late last year showed that the performance of the rears degraded very quickley, particularly when a soft compound was used.
so the teams that they need to get as much weight off the rears as possible and towards the fronts. the simplest way to do this is to shorten the wheel base. another is to make the car lighter so you have even more ballast which you locate as far forwards as possible.
it is possible that last year ferrari couldn't bring ballast any futher forward as they ran out of room the longer wheel base will free up some space there without putting it on the front winh slowing down how quickley the car can change direction.
