As of right now, performance wise it's going to be har to touch for porsche since porsche doesn't use as many electronics to keep good traction as ferrari and porsche still isn't using semi-automatic gear boxes(dsg will come out a little later with the 997's). But one car that actually will be on par, dispite the lack of electronics, is the new Z06. The Z06 runs high elevens in the 1/4 and thats with lack of traction control, we just need to see a comparison of the two on a road course.
