Cast Rotors

Anyone use these on their XJ?
They claim to be "better"
Less warpage if any at all.
Better braking?
Whats the deal with these?
I use my XJ solely to get me everywhere. Its my only car. Snow, rain, street. Rarely take it offroad.
Are they worth it?

Less warpage? True.

Better? I think so but others may disagree.

No warpage? Impossible.

Better braking? Nope -- that's a function of swept area, friction material (pad lining), and booster/master cylinder/caliper design and sizing.
