2. Vibration at or above a certain speed with everything else being the same often indicates a wheel (or wheels) that are out of balance.
3. I like the Z1 2-piece rotors on my car but for a non-competition or HPDE car they are probably just a waste of money.

Thanks for the reply. Probably a coincidence of timing from two separate things then.
I'll give the hard braking a try, then get my wheel balance checked.
Car won't see more than hpde, but reducing unsprung weight is always a good thing and they're pretty and I just want an excuse
