I was curious if you would gain anything from the slots in the rotors even though they do not go to the edge. Just wondering

In my opinion, I wouldn't think that the means don't justify the cost. They are allot of money, I would save that for go fast mods personally........

They advertise the grooves as wear indicators.

They wouldn't be very effective at venting pad gasses or water. And I believe I paid $74 each including shipping for my powerslots on Brembo blanks.

well it was sent to my email as a new product and i am getting ready to get better rotors and pads and possibly struts. There is a lot of twisties so I am looking to enjoy them and power is only good if you got good parts underneath

The ATE "atom" grove has a good reputation for venting pad gasses and shedding water.
They are the same as any other good sloted rotor as far as effectivness and performance is concerned.
The rotors Bill has will do the same job and you can invest the savings in better pads.

get the power slots
