R1 Concept rotors for KH setup

Turn disks ? I never turn them , better just to change them if they are scored or whatever . Drilled or slotted disks look good , but not much benefit besides that , pad choice will bring more benefit .

yea you can turn discs as long as there not under spec...

some places will turn slotted/drilled rotors if they have a flywheel "lathe"(more of a mill)

and slotted and drilled rotors can bring great benifit if you are slamming on the brakes or alot of contunal slowing...

the slots and holes alow the brake dust and heat to get around the pad and also enter the"vented" area where the heat and dust can be released...

but on a normal street car yea they probably wont do a whole lot...
