Do your front rotors on the top where the venting area is have a weird groove worn out on them..i never noticed it when I installed them so Im very curious.





And im not saying its worn down the rotor itself is perfectly round its a groove located on the out side of the rotor i will take a pic later if i really need too.

 

All brake rotors have that....not just stoptech's.

Take a look at your stock brembo's....

 

Yeap, my experience as well with all three sets of rotors.

 

oh okay thanks guys I was a little worried.

 

Its how the balance brake rotors NooB
