Cross drilled and slotted rotors worth it





Additionally, cross-drilling increases the surface area of the disc, and this aids in disc cooling (one factor in brake disc cooling is the ratio of surface area to disc mass).
I put these on my 07 2500HD Classic.
Where To Buy, installation Guide, break-in Procedure, drilled, Slotted Plated to Perfection.
Do it, you wont be sorry.My temperature sensors at my wheels have showed that they dropped my average braking temperature by about 22 degrees F on the front and about 17 degrees F on the rear.With a direct OE fit and vane count, there are no special modifications needed on your car, truck or SUV.Stick with the good ol' smooth as a babies behind rotors.Ive never had such great control of my Jon Boat trailer until now.That heat is then radiated to the atmosphere as air flows over and through the rotors (and the rest of the braking system completing the conversion of kinetic energy into casino gaming trends thermal energy.However, the cost of implementing this is increased due to the need for unique left- and right-hand discs.Although it only came with cross-drilled/slotted only, I made the plunge on that set and they've been great so far in the year that I've used them.As most of you already know, the basic function of a brake disc is to provide a mating surface for the brake pads so that when you stomp on the brake pedal the friction material that makes up the pad is squeezed against the rotors.Cross-drilling puts holes perpendicular to the flow of air - they have no cooling effect whilst the wheel is turning.



Therefore they provide better braking at the same temperature.
Weve also had requests to explain why many slotted rotors these days have curved or J-hook shaped slots, rather than straight slots.
Additionally, there are requirements for the hole size and placement of the holes, including distance between holes, distance from braking surface edges, distance to disc vanes, angular offset of holes and more.
Due to the fact that track testing is required, and thanks to strong collaboration with many top-level racing teams, Brembo has developed a very broad knowledge of the many different types of slot shapes possible when machining discs.
But when you consider just how vitally important the braking system is to safety and performance, it shouldnt come as a surprise that industry leaders like Brembo are constantly looking for ways to improve the design of their brake discs.Since this type of extensive R D is really outside the scope of all but the biggest brake system manufacturers, a lot of what youre seeing in the aftermarket are companies copying what leaders like Brembo are doing with respect to slot shape, slot spacing.All I can say is WOW!Weve received quite a few emails lately asking us to explain what the advantages are of cross-drilled and slotted rotors, as compared to the blank rotors most cars come standard with.As Mark further clarified, Modern brake pads dont have an issue with out-gassing like they did many years ago, but the cross-drilling is still helpful for use in wet conditions, especially when the pad surface area is large.A cross-drilled or slotted rotor has less thermal mass and thus heats up faster and fades faster.They went on as indicated and a friend and myself had them installed in less than an hours work.I was tentative with buying these not sure whether they would fit and work right and what a pain it might be to return them if something wasnt right.Towing a camping trailer really did a number on my stock rotors.



Who knew so much technology goes into these seemingly simple iron discs (the material composition of brake rotors being a topic for another month).
