If drilled and slotted rotors did nothing please explain most race vehicles of all genres using them like F1 , road racing of all cars , 1/4 mile race cars etc.... Yes I agree it is preference and not everyone wants to spend money on good parts and would rather do the job 2 or 3 times to get the same life as some better products cost , but could have spent less doing it right the first time. Yes I also agree with some drive their cars/trucks/bikes harder then others and some may never feel the effects of said better brakes , but I noticed it right off as I mentioned in the original post. I also think I will be doing braided lines as I do know they help to put the pressure to the caliper and not in line expansion . I think a lot of opinions are because lack of actual use of certain products not that anyone is stupid . I looked at prices for good pads and rotors and with the sale it wasn't getting any better. One of the nice features of them is the coating inside and out to keep rust down and with boat ramps / off roading/ river crossings this is nice feature. Ill say also thet hard driving and hitting the brakes in stock fashion I am alittle disappointed in the stopping distance , but I know it is improved and no I know this isn't a race car but it is a performance truck . Anyway again thanks to the guys over at Freedom Motorsports service , response and products 100% happy with purchase !
I don't think any current F1 cars use drilled or slotted rotors.
The only real benefit from them is when you have pads that off gas, with the slots or holes the gas has an exit path.
Otherwise, they just reduce the contact area, decreasing stopping power. They also reduce structural integrity, increasing the chance of warped rotors.
They may cool a little faster but I doubt that would be enough to offset the drawbacks noted above.
As for weight savings, when each wheel/tire combo weighs ~100 pounds and your truck weighs over 3 tons...
They do look cool, though. But I've had too many drilled/slotted rotors warp (yes, even on very expensive Baer brake kits) to ever bother with them again.
