Yeah I was wondering about this. If you look at the pics of the Ferrari 2008 v 2009 you'll notice that the driver is MUCH farther forward for 2009. Apparently McLaren didn't think they need that much front weight.
Interesting, the difference in wheelbase.
Hi, I don't want to appeat pedantic but I couldn't help noticing that this image (I've seen it else where by the way) isn't particular accurate. The difference in wheelbase is no where near as dramatic as it appears here. I suspect it can be measured in millimeters.
