As for the new front end, they basically took a chunk out of the nose above the front wing, thereby allowing for better airflow = more downforce and lower drag.
As for Montoya being held back info, etc. from the team due to his impending departure in 2005, that will not happen until he is out of the championship picture in 2004, and perhaps not until BMW is out of the Constructors, which IMHO will be late in season ... if at all (hopefully ...). Firstly, Williams is in its longest ever dry spell as far as Championships of any kind, and they've got the best pieces (JPM & car) in place to do it since '96. Secondly, Frank and JPM still get along ... Frank knew of JPM's plans with several races to go in 2003 and still supported JPM to the end. As Frank says (of JPM) ... "He's a racer." That's just what Frank wants. On the other hand, his history with such drivers never seems to be long term, esp. as he doesn't like to pay big $'s. Then again, JPM also has said, he didn't leave for the amount of money, it was instead because Ralf was paid more than JPM (ie. the principle of it). He also doesn't like the BMW-enforced favoritism shown to Ralfie.
Finally, as for the McLaren, so far it is rumored to be approx. 1.0 sec/lap faster than the Williams, after their first rounds each of testing at Valencia.
It's gonna be another great year in F1 !
Just hope we can keep the U.S. GP going ... ticket sales are way down for last 2 years :frown:
