PS = DATA FROM 2006 Season

[Scotracer]

Thanks for that data. The Gs will be a bit lower for 2008 as the tyres aren't as good as 2006.

I will try to find braking data from 2008 Chinese GP but till then we have to wait .

2008 -2006 comparison data will show the evolution rate of modern F1 cars and how the rules effected car's performance

FERRARI F60 FRONT BRAKES - 2009 GP CHINA





BRAWN BGP001 FRONT BRAKES - 2009 GP CHINA

[Slow Polk]

It looks like Ferrari is creating a clover shape in the cooling vanes. I assume this is to increase the cooling surface area?

Upon further inspection the pic shows they have actually dimpled the inner surface in the vanes to further increase area. I would be interested in seeing what CFD/heat transfer analysis they have performed on those rotors.
