I have a new set of drilled / slotted rotors. If the venting vanes are not angled can the rotors go on either side or is there a correct direction of rotation?

 

My powerslot cryo's are directional. Which brand do you have? Typically the part number will be different for thes types of rotors.

 

Prime Choice drilled / slotted rotors. My RR caliper stuck a few days ago, ate the pads down to the backing plate and wasted the rotor. The boxes are labeled R and L but the direction of the slots/ holes are opposite of the last set I got from the same company last fall.

I did a lot of research on the 'net last night. It appears the only thing that really matters as far as direction goes, is if the vanes are angled. These rotors have straight vanes. I shot Prime Choice an email and will post their response (if I get one).

 

I've used Rotopro's drilled and slotted for years, best bang for the buck and the are the bomb for stopping.
