I woke up at 5:00 and it was raining here, so I looked at the radar and wished u good luck and went back to bed. lol
They are solid. I won't run drilled, they are a recipe for disaster as you've stressed the metal drilling holes in it, cracks develop quickly. Slots were designed to take the material off the brake pads, causing faster wear.Are you using slotted or drilled rotors, or are you warping the flat/solid OEM ones?
