Yup.

Yup.

The four-wheel slide is how it's supposed to happen - apex a little
slower than normal, wait for the front to go, power on until the back
goes, and steer with both throttle and wheel.  Once you get used to
how much space you need, terrific.

Won't work with your car now, no matter which axle you put the different
tyres on.  A real problem, since P700Zs are no longer available at any
price.  Pirelli are apparently promising P7000s for September - let us
all pray.
