It will be interesting to see how this rolls out. Pirelli have some wonderful tyres and they grip levels on the P-Zero's should be phenomenal.
As far as your set up goes, well that is really tough on you both. Surely the need to modify the car is not that great? Using the normal step up in tyre size and profile adjustments will take car of 99% of the work? When you guys were here last there looked to be plenty of clearance in terms of width and ride height (I appreciate that you weren't running TA ride heights due to the farm track

)
The other thing is, you guys are serious about running in 2012 not 2011. Anything could happen by next year.
