Imo it looks good. I have delt alooooot with brakes working on cars and trucks and bikes (road) not atv or feeling much with mud and dirt, but a filled and slotted rotor helps with cooling and keeping dust down. By helping to remove the dust you will have a little more friction area for the pad and disc. Now with drilled rotors, that's a little different. Basically a drilled rotor is used or "was" used back in the day to release gas from older asbestos type pads. Basically the gas would get caught between the pad and rotor under heavy braking. Nowadays we really don't have to worry about "gassing" (unless you eat lots of burritos) lol.. but with new ceramic low dust pads is not an issue. But with slotted rotors and drilled rotors are basicly cosmetic imo because unlike a heavy vehicle your really not putting your brakes under that much stress.. But I'm honestly mixed in what i just said because i brake hard sometimes but I'm only a weekend rider. On mx i can see how it would actually help with slotted rotors to remove debris, and i can't see real heavy braking to warp or crack a rotor on an atv unlike a car or truck or road bike. Correct me if I'm wrong i just personally don't hit the speeds and brake so hard to get my brakes that hot.. I'm sure some of yous do though.. Imo i don't see nothing wrong with drilling or slotting your rotors. It looks good keeps them a little cooler and i can't see heat affecting the integrity of the rotor.. Btw you will know if your rotor or rotors are warped because you will feel a pulsing in either your pedal (A) atv/bike rear rotor warp you will feel it in the rear brake pedal,,rear rotor warp in vehicle you will most likely feel it in your seat sometimes brake pedal. (B) front brake warped rotor you will feel a pulsing in your front brake lever bike/atv now in a vehicle you will most likely feel it in your steering wheel and brake pedal under braking,, vehicles usually are about 70/30 some 60/40 when brakes are applied or in that area higher number for front brakes so 70% front and 30% rear when brakes are applied.. now that's for a vehicle not a bike or atv because they use different levels and pedals for front and rear.. sorry let me stop now because i can go on with brakes for days.. Any ways nice job on the drilling of them. What type of bit did you use because rotors are hard..
