Camshaft Related Questions

After looking into an upgrade for the cams on my car (its a 99M3, US Spec), I've only come across one set of schrick cams for the S52B32US, and they're 264/256.

#1: Does Schrick make a more aggressive cam for US motors?

#2: Are the sunbelt cams any good?

I've heard all sorts of discussion on the topic, and some people saying schrick is the way to go. The Sunbelt Cams are much more aggressive, and I can't see them making less power up top in reality.

#3: Are there any other options besides Schrick and Sunbelt?

And finally

#4: What limits how fast we can spin our motors? Is it the hydraulic lifters, or will the rods let go above a certain RPM? What is the maximum safe engine speed for a street car that will see occasional AutoX and track use?
