Any freshly-machined rotor will be far less likely to squeal because the machine marks alter the stick-slip behavior (stiction) and change the vibrational frequency. You can prove it to yourself by sandpapering the hell out of any currently-squealing brake rotors you may have. Fresh pads, likewise, will have a "rough" surface. It's when both of these surfaces become polished, or "glazed" that squealing can be a problem.

So.... you may still need to bed them in. Or, possibly they'll be fine regardless. Time will tell.

 

you can't stand brake squeal and you put on HP+ pads which are more track oriented then street and which are known to squeal like banshees...

 

They came with the kit

 

Nice link. Thanks swoope

 

Yeah thats good stuff. I did mine good IMO.
