Pulling a Naz...
The Focus has one clear advantage over the Mini that we must learn to use: Horsepower.
The Mini weighed in at 2450 lbs, and my Focus with under 1/8 tank of gas was around 2500 lbs.. We've got tons of low end torque compared to the Mini. With Konis, the need for an LSD is reduced somewhat, allowing us to get more power down out of the corners.
I think that a well driven Focus on a horsepower or transistion/technical course can do well against the Mini.
Where the Mini excels the most is a g-force type course... The Mini has more rubber on the ground, and seems the follow the sweepers like it is on rails!
Many people including myself have been using ProSolos to determine where the Mini should lie... which really isn't a good idea. We need to give it time to play out, and see how it works out on all types of courses.
I know that I'm going to have fun at Nationals against the Minis no matter where I end up.
