Check the Nissan Motorsport website as well. The Calsonic car is 542bhp/1260kg
Going by pics of the Calsonic car, front camber is extreme. You're looking at about -5°. Rear camber would be about -3°.
Take note, the current R32 NISMO in the used car dealership is the one you want to have  as it looks like the real car withe the front bumper vents. However, the 1994 V-Spec car has a larger standard wheel & tyre package. So, in terms of stance, it looks a little closer to the race car. Making both into the Calsonic car would be a good idea.
