I am going to be opinionated here for a bit, just like in the other post (the DZ coilover post). I am kinda tired of unqualified answers, so I speak from a personal and professional experience with brakes.
Here we go.
Crossdrilled rotors-by design, crossdrilled rotors were designed for track use. Why? Because, when you drill holes in your rotors, they are designed to dissipate heat (not to rid of brake dust as most people think).
Slotted rotors-by design, slotted rotors were designed for long wear use. Why? Because, when you slot rotors, they are desinged to dissipate brake dust. If you look at a slotted rotor, even by common sense, the slots aren't straight, rather go in a clockwise direction, causing any left over chunks (ya'll know which brake chunks I'm talking about) to be pushed out of the rotor, as the pad contacts the rotor.
Now, crossdrilled and slotted rotors provide best of both worlds. I know, as I've hated my brakes since day sixty five or so (my brakes started squealing on the Max when it was 65 days old-1900 miles on it). In two years, I've put everything on my car (you guys remember my fiasco with the great
EBCs that wore in less than a thousand miles...). I've tried generic pads, brand name pads, everything. Finally, after almost giving up on the brakes, I decided to give Brembo blanks (slotted/drilled by SWC here in AZ-private company) a try. I love them. Anyone in AZ that has ever been in my car can tell you the following things
a)They rock
b)They look awesome
c)NO SQUEALING, NONE, NONE, WHATSOEVER NO SQUEALING
d)Did I tell you they look awesome
e)Increased stopping power
(I ask any local non-believers to take a ride in my car, I would be happy to allow them to drive it just so they can tell you about the brakes)
Finally, the difference in rotors is not much, but it is there. You all have heard of cracking rotors, warped rotors and so forth and so on. I PROMISE YOU ALL, if you buy good stuff, it will last. If you buy junk, it won't last. Be aware of companies with no name brand slotted rotors, you must be aware that there are only a handfull of companies that in fact slot/drill Brembos, so make sure you only buy the good stuff.
Any ????s, please let me know. If I have skipped anything please let me know.
