bagged93gmc

ok so we have been searching the internet for 3 days now. and does anyone know which way a drilled and slotted rotor goes on? on my friends car the front ones go from big to small and on the rear they go small to big. please help this is a mind boggling situation.

Make sure the slit/slots/ ***** hahaha are coming in contact with the brake pad on the inner portion of the rotor surface and then leaving contact with the brake pad at the outer portion of the rotor. The hole sizes and order should be the same idea. The smaller hole I would guess should come in contact with the pad first and the bigger holes last. (I should not have to mention it but I will, this is assuming the car will be moving forward)

If these are going on a bagged 93 gmc then most likely they are just for show so just put them on any way ya want

Good luck I hope you can get them on within a week
